Decided I'm not going to die wondering, so I ordered the composite materials and vacuum equipment for a C50 and employed a kiwi boat builder/foreman to ensure it is built to a high standard. Also to give me time to work on other projects such as the cargo proa testing and certification, recycling plastic, dessicating (not composting) toilets, electric cars, solar farms, motorised shipping containers (maybe) and advocacy for remote villagers.

The boat will be built here (CATD Fiji) by graduates of our 2024 Sustainable Boat Building Course, starting in February. We will video the build, incl screw ups and record the costs and hours. Build time is unknown as building village suitable boats (fishing canoes, solar/electric water taxis and mini cargo proas) will have priority.

Materials spreadsheet attached. Enough to build all the composite parts, including unpainted hulls, decks, fitout, 2 carbon masts incl tracks, booms, beams and rudders. Amounts are based on areas, plus ~10% wastage, plus rounding up to next roll, box or sheet. Shipping, tax and duty will add about 35%. Tax and duty should be reclaimable if the boat is exported.

I'm not sure I will be able to resist the temptation to experiment, but the intention is to build it according to the plans. ;-). Only diversion so far is to use 20mm 100 kg foam on the bottom instead of 25mm 80 kg.

UPDATE 9
Zero emission shipping things are starting to happen at CATD. Not least because we have usable boats in the water. One of the upshots of this is an increase in curious visitors, many of whom are doing interesting things, but need sustainable transport to make them happen.

We fitted the 5 x 300W solar panels to the Rewa water taxi prototype built by the students and powered by the outboard converted from petrol to electric. It worked a treat. The attached photo and video show it operating under 2 of the panels (600W, less than 1 horsepower), no battery. Top speed was 4 knots, with 2 people on board on a cloudy day. We are now waiting for MSAF approval prior to fitting batteries and taking it down to Rewa, a 6 mile open water trip, followed by 9 miles of river. Once it arrives, it will be used by as many drivers and passengers as possible and the feedback will be used to design the production version. These will be built by graduates of the Sustainable Boat Building programme in the new UN Innovation Hub at CATD.

25 years ago, I realised that kites are by far the best way to use the wind to power boats. Why? They are attached to the deck, so there is no heeling, they require minimal deck gear so they are far cheaper than conventional rigs and they can be flown high where the wind is stronger and more consistent. On the down side, (and what I and many others have spent a fair bit of that 25 years looking for solutions to), they are difficult to launch and retrieve on a small/medium boat, have the potential to unexpectedly quadruple their power output if not carefully controlled, are a nightmare if they fall in the water and have kms of small diameter string which tangles easily.

I spent a couple of days pre Xmas with old friend Trevor Jack on KitetiK, a 15m harryproa used for testing kite ideas. We used a kite handling system devised by Trevor and a 17 sq m/183 sq' (projected area) paraglider, modified to fly like a kite board traction kite. It took a while to get it set up, (once we mark the lines it will be set and forget) but then we could leave it and steer wherever we wanted to from hard on the wind to broad reach with no one touching the kite. Launching and retrieving was simple, using the mast to hoist and retrieve the kite. Once flying, all the loads were taken by a single strong point on the deck. This is a huge contrast to a sailing rig where the sail force acts half way up the mast and the loads to shape, control and support the sails are an order of magnitude higher than the force propelling the boat. As a bonus, the kite loads are lifting the boat, whereas conventional rigs act to heel the boat and depress the bows.

17 sq m is about 1/3rd of the designed sail area, not much more than a conventional storm rig. We managed 6 knots top speed in maybe 10 knots breeze (no white caps, despite wind against tide) shunting through 90 degrees upwind.

This performance and ease of handling was impressive enough to justify bringing Trevor and Gavin Mulvay (kite, electronics, EV's, and a whole bunch of other things guru) over to Fiji to try it on the tender for the cargo proa. Gav also cut and sewed a different type of kite which may be easier to use.

I had 2 weeks to finish and install a lee (actually a weather) board and a mast (one of the booms for the mini cargo proa crabclaw rig), make a paddle and set it up for steering. The mast's sole purpose is to launch and retrieve the kite. Once it is flying, the mast does nothing and is unloaded, or so we thought.

The guys arrived and we spent a couple of days sorting things out, doing some test runs, installing the bridles on the kite Gavin made and then set off for Leleuvia, 12.5 miles/20 kms away. A broad reach, barely 10 knots of breeze, with the paraglider/kite from KiteteK. Raising and lowering it was simple using the mast. Pull it up, release a string and it gently fills. How gently is controlled by the string release speed. Reverse the procedure to drop it. Shunting is a couple of seconds of pulling lightly on one line. Faster than the time it took to get the paddle from one end to the other.

Top speed was 9.6 knots, all went smoothly until the mast broke between the bearings. A function of the small bury (distance between the bearings) waves from the side and a spar not designed for the job. Nothing to do with the kite.

We spent 2 pleasant nights at Leleuvia and took the boat for a shallow water reach along the beach with a hand held 2.5 sq m/27 sq' kite. Got along at about jogging pace with not much leeboard down. I'd definitely carry one of these (maybe a bit bigger) as an emergency kite. We also test flew the kite Gavin had built (see attached). It needs tuning, but has potential. We jury rigged the mast with stays for the trip back. Repeat of 9+ knots top speed in similar breeze but the stay angle was insufficient, so we broke it again in the cross seas, nothing to do with the kite. We had a play with a couple of hand launched kites, then the breeze died, so we called for a tow to CATD. Gavin had to go home, so Trev and I rigged an inverted Y mast using bamboo. Much stiffer, but we managed to break this too. Definitely a function of the kite this time. We learnt a lot of lessons, not least that big kite techniques on small boats are difficult and kite selection is important. On the bright side, the problems with the masts will not apply to the cargo proa, so we are proceeding with the build of 2 large kites. see videos at https://www.youtube.com/watch?v=-uK7q7iCaGg. and https://www.youtube.com/watch?v=-uK7q7iCaGg

The tender is an 8.5m/27' catamaran with 400mm/16" wide, double ended hulls, flat bottom and no rocker. It weighs about 250 kgs/550 lbs and draws about 20mm (3/4") empty. A bit more than double both of these with us three and our gear onboard. The draft enabled us to skim over coral with the leeboard up and the steering oar out of the water to avoid having to go round outcrops. Shunting (couple of seconds and almost no effort) meant we could reverse immediately if it got too shallow. A definite plus in this part of the world. Due to the hull shape it is easy to steer by weight shift with the kite attachment point amidships on the lee deck, opposite the leeboard (actually a weatherboard). Move a person a metre or so and the steering paddle is not required. The hull shape also means that drag is unaffected by shape changes when weight is added.

We were given a 6 kw/8 hp electric outboard and battery in lieu of grant money owed. We fitted it on the tender and with 6 people on board did 5 knots using 1 kw (1.3hp) of power. Impressive enough that both Gav and Trev intend to build smaller versions of the tender. Four of us took it to Leleuvia for lunch, came back in the afternoon, had almost enough battery left to repeat the round trip. Petrol cost and emissions? Zero. Top speed was 11.2 knots, which implies the prop is a bit fine, we will test some others.

The students took the tender for a blast and managed to whack the hull with the outboard, at full speed (see pic). Due to the multiple bulkheads in the hulls, it didn't sink and because it is a flat panel construction, the fix was a 20 minute job with a backing plate and a couple of layers of glass.

The end result? We are not there yet with a solution to zero emissions small/medium boats, but we are a lot closer than we were with the conventional and wing rigs. The rig works well enough to buy a couple of kites for the cargo proa and see how it goes. There will have to be a lot of disadvantages to outweigh the advantages: no heeling loads, low cost, long life, easy handling (no winches, 2 finger control most of the time), light weight of the kite and mast, no deck gear, easily learnt basics, a simple problem solver mode and sailing with the bows lifted instead of being pushed down.

I'm modifying the cargo proa and will launch it when we have MSAF approval. The mods aren't simple as the boat is set up to do everything from the windward hull. Trev and Gav will be back with the new kites for the next chapter when it is launched .

Gavin had a small waterproof electric motor with a 3D printed housing which he uses to propel his 7m trailer sailor. We mounted it on a piece of wood and used it to push the tender, then dropped it in the water. A floating outboard! (see attached). This type of motor opens up some interesting possibilities for converting petrol outboards, powering canoes and building our own low cost outboards.

There were a few surplus to requirements solar panels available, so the students put them on the roof of the boat shed, Dels the sparky wired them up and we have Fiji's first solar electric boat recharging station. Not particularly elegant, but it will do the job.

We are organising Boat Master courses for the students and staff so they can take the boats out fishing and snorkelling. An impossibility with the outboard on the 8m CATD fibre due to the cost of fuel.

I spent a couple of pre Xmas days working with the plastic recycling people. Built 2 frisbees (see attached) from plastic bags and scrap dress material. The equipment to process unwashed and unsorted plastic is on it's way from China, we hope to be operational in April. The frisbees are part of the school program planned as the next step after we get set up at CATD.

Last week we attended the award ceremony for the UNDP grant awarded to CATD for a project to develop mud brick houses, similar to the ones built in Ba in 2005, which were the only buildings to survive cyclone Winston in 2017. One of the people involved in building them is now at CATD. There is potential to use the glass we are crushing as a sand substitute and perhaps a couple of uses of the recycled plastic in the construction of these houses. Interesting stuff.

For those who are curious about CATD and what it is about, have a look at this video.

There are boat building workshops in the pipeline for Matuku Island (Lau group) and Taveuni, both beautiful places. I won't be running the workshops, but intend to visit and have a look around.

In Harryproa developments, www.harryproa.com is back on line, complete with some stunning new renderings Steinar has been working on. There are now 2, perhaps 3 C50's to be built here, once the Innovation Hub shed is complete. This is an ongoing process, with a lot of disparate elements that need to come together before construction can begin.

We are having a great time, with great people in a great place.

Update 8
Following on from the village women's canoe building workshop, we got requests for more workshops and chose the village of Dromuninuku, 30 kms east of the beautiful town of Savusavu, Vanua Levu. The cruising around there is fantastic, and almost free of cruising boats, despite Savusavu being a clearing port for Fiji.

Salote and 2 of the other graduates from the April workshop (Siana (Dromuninuku) and Lo (the neighbouring village of Naweni)) ran the workshop, producing a catamaran canoe in 9 x 4-6 hour days. Not bad for a group of women who did not know what foam, epoxy or fibreglass were when they started.

Sue (my wife) and I oversaw the workshop, but had little to contribute. We also got a small taste of village life, an experience neither of us will ever forget. Villagers don't have much in the way of possessions, but are genuinely happy, in stark contrast to many westerners I know.

The canoe building is a big deal, as shown by the attendees at the award ceremony. Representatives from the UNDP, the Provincial Council, the Ministries of Fishing and Health and CATD handed out certificates to the women, then watched as the boat was launched. The ceremony speeches emphasised the importance of small boats for fishing (neither village has any, they fish standing in the water inside the reef at high tide), the need for lightweight, easily built (no power tools, all right angles), rot proof boats (not plywood). One person did comment that this is what traditional boats would look like if foam, fibreglass and epoxy could be obtained from coconut trees!

On the first day, we took a stroll along the beach and I commented on the rubbish. Two days later, the women had organised clean ups at both villages and beaches, organised the Health Department to pick up the waste and set up an organisation called Women on Waste/WOW, whose mission is to do similar clean ups in all Fijian villages. The clean up was held half way through the workshop and all the village kids got involved. It was cool walking along the beach picking up plastic with 20 laughing kids helping. They remained working till the very end, which is more than some of the adults managed. Result was a couple of tonnes of waste collected. As importantly, they cajoled the Health Department into permanently providing 3 cu m rubbish bags and a truck to pick them up when they are full.

The day before we left for Dromuminuku, the students at CATD launched the prototype solar/electric water taxi. Another box boat, bult in a few weeks. While I was away, the students removed the petrol power head from a 40 hp outboard and are replacing it with a 10 kw (13 hp) watercooled brushless electric motor. The water taxis typically use a 15 hp motor to drive a 6m hardwood skiff. It will be interesting to compare performance. The roof of the prototype is 5 x 305W solar panels, the boat should be fuel free as long as the sun is shining.

I have been talking to a New Zealander who reckons what we are doing in Fiji is worth supporting and who, coincidentally, wants a C50 built. On the ferry on the way back from Dromuninuku we had a meeting with the UNDP about the next step in the project. The upshot was that they have provided support to set up a boat building operation, a classroom and a plastic recycling centre. Artists impression is (or soon will be) at http://harryproa.com/?p=3788

This is the first stage of the Innovation Hub being set up here at Nadave. The boat will be built by the graduates from the Sustainable Boat Building course we ran earlier this year as part of the co-operative approach that CATD uses to continue the education of ex students so they can, if they want to, start their own business. This is seen as key to the future security (economic and political) of the country. We plan to employ a foreman or two who will supervise and teach the students how to infuse composites and build boats to western standards. My role will be to make sure it runs smoothly. IF ANYONE IS, OR KNOWS OF SOMEONE WHO WOULD BE INTERESTED IN THE FOREMAN JOB, please let me know. [email protected]

When the workers are not working on the C50, they will be building cargo proas, mini cargo proas, canoes, Harriettes and Eboats for local use. If the C50 build is satisfactory, more will follow.

How important is all this? 3 weeks have passed since the meeting on the ferry. Yesterday, the UN Assistant Secretary-General - Ms. Kanni Wignaraja and the Fijian Minister of Rural Affairs performed the ground breaking ceremony for the building. The shed will be as environmentally sustainable as we can make it as an example of what can/should be done. It will also be a zero waste boatbuilding shed. Fibreglass offcuts, used resin containers, gloves, wrapping materials, floor sweepings, etc etc will all be recycled on site into useful building material.

We intend to employ a videographer to "You Tube" the build and are discussing with The University of Sydney a carbon footprint analysis for the boat, shed and other CATD projects.

The zero waste aspect will be facilitated through funding it looks like we have received for equipment to turn unsorted, unwashed (the expensive parts of recycling) waste plastic into structurally reliable products, using a low temperature solar heater and equipment that will fit on the back of a small truck. We plan to take this around schools, villages and resorts to show that recycling is worth doing. There will also be a village suitable glass crusher to turn bottles into sand, reducing landfill and replacing sand on beaches and in concrete.

One of the things we learnt at Dromuninuku was that villagers are not messy people. They simply have nowhere to put their rubbish and can't afford to have it taken to the landfill. The first step is therefore to get recycling bins in villages, schools and resorts and demonstrate that they have value. We intend to produce the bins from waste plastic for bottles, cans, plastic and batteries, all of which now have value, making them worth collecting and recycling. Any money made from the recycling will be put towards arranging regular pick ups from these bins.

Fun times for all concerned.

Boat progress has been a bit slow, but steady. We have reached our first set of UNDP targets and qualified for the 2nd tranche of money. Both good feelings. The boat is ready to launch to test the rig and rudders, but the launch has been delayed until we get the ramp fixed where the river has eroded it. This involves building a retaining wall and some back filling when the guys and gear have finished building the new 100 pig piggery.

Jobs off the to do list:
Installed one of the telescoping masts so we can test a third of the first wing (5 x 1.25m high panels). The mast telescoping arrangement needed work, and has been altered. Also built a stopper to prevent the top mast going through the bottom of the boat if something breaks.
Decided the fibreglass cockpit deck was a poor solution, so chopped most of it off and replaced it with net.
Completed the rudders, including the kick up mechanism and installation of the whipstaff. Will run the lines when it is ready to launch.
Put some carpet in the ww hull. Brightens it up nicely.
Made a crude textile clutch which works well for holding the top mast halyard, but may (will!) have some strength issues on bigger loads. I have some kevlar braid somewhere which will be much better.
Built a couple of wing camber inducers from carbon tow. Not sure they will work as the loads are not known for certain, but they are a good start.
Added inspection hatches to the lee hull, experimenting with low cost ways to hold them on.
From the "you've got to laugh or you'd cry" department: I spent half an hour with the big grinder prepping the side of the ww hull for painting, then had to knock off for a ceremony and lunch to bless the new digger. Got back to the boat at 5 (ceremonial lunches are not trivial affairs, the rest of the attendees were still going strong on the kava at 9 pm) and painted it while being chewed by mosquitos. Was woken in the night by torrential rain. The result is attached. Once it dried, I applied another coat which seems to be well stuck. Cheap water based house paint is good stuff. ;-) The copper epoxy has not been sanded to expose the copper yet, so the paint on the antifoul will be easy to remove.
The sailmaker supplied a couple of test wing coverings which fit like a glove. He understood immediately what I was trying to do, and is enthusiastic about teaching the students to build crab claw sails as part of the UNDP funded 'sustainable, island suitable boat building course' we are running at CATD in the new year. The plan is to build PET foam/fibreglass versions of the Marshalls boats, with 2 side mounted kick up rudders, no leeboard and a track for the mast. The boats should last indefinitely, with no maintenance beyond house paint on the bits that are in the sun. No power tools, building jigs, nuts, bolts, screws, plywood, timber, very little metal, 2 measurements (length and width) per component and a 2:1 epoxy mix ratio suitable for use in 30C temperatures.
Each 3 month course will build 2 boats, including spars, rudders and sails, which will then be used to teach sailing and seamanship.

Feedback on this project is that the sailing mini cargo proas are great for fishing and non urgent freight and passengers, not so good in low wind areas, fast flowing rivers and narrow channels. A low drag, small outboard motor boat would be a lot more suitable and a big improvement over the heavy fibreglass skiffs with their big gas guzzling motors. These will be built the same way as the mini cargo proas. An option will be to put a roof on them for shade and solar panels. These will power small outboard motors where the petrol power head has been replaced with an electric motor, reducing maintenance and eliminating fuel costs. A slightly larger version of these outboards is going on the cargo proa tender.

Some of the other things happening:

Spent a weekend at Beqa Island to chat with the islanders and check out the water and location as part of the never ending quest to improve the boats. Navigating to and from Beqa is going to be a challenge. There is only 1.5m/5' to 2m/6.33' of tide, but the land area grows considerably at low tide, and there are coral outcrops all over the place. The Navua river where we boarded the fibre has a wide bar. We touched on the way out, had a moderately exciting surf on the way back. Lots to think about to reduce the chances of strife. Fuel costs are killing the islands, the excitement about the cargo proa and mini cargo proa was quite gratifying.

Visited Rukua village to help with their 'clean up the village day'. Grubby, but it was educational talking to the villagers. They collect all their rubbish, then take it to the mainland in outboard powered fibres/pangas/banana boats and pay $150 to truck it to the tip. Most of the load is air in cans, bottles and plastic containers.
I came back, googled can crushers and asked the welding teacher to build one, which he did. $US20 each from Amazon, could be a good earner for CATD if we sold one to each village in Fiji. A truck full of uncrushed cans costs money to take to the recyclers. A truck full of crushed cans and the village makes money.
Designed a plastic melter/press, to either make something useful (floors, paths, walls) from the scrap plastic or just melt it into blocks for easier and cheaper transport to the tip. I'm waiting for a 200 litre drum to build a prototype. A bonus of melting it is all the smelly stuff gets evaporated off.
Crushing glass bottles and jars is a no brainer. The result is effectively sand which can be tipped into the water, spread on an eroded beach or used in concrete. The prototype hand operated crusher is built from an old gas bottle. It is half built due partly to a measuring error (mine) and partly as the welding crew have been called on to build a jetty over the slip to access a 12m/40' floating pontoon. This will replace Bau Landing as the terminus for the Leleuvia ferry. In true Fijian style, the jetty was built in a couple of weeks and covered with planks chainsawed from a couple of pine trees which were removed to make a flat area for the waiting room, which morphed into a coffee shop, probably made from a container CATD has. Instead of cutting up and hauling away the sunken sand barge at the bottom of the slip, the farm manager had the brilliant idea to use it as a foundation for the pilings. The floating pontoon will make working on the cargo proa in the water a lot easier. I love this place!

A year ago, Rukua village was gifted one of the 100 plywood camakous (18' outrigger with crab claw rig) which were built and used for a TV reality show. They were built in a hurry, did not get much epoxy. A local group fixed a few of them to give to communities to encourage sailing and reduce fuel bills. The Rukua one is now more holes than plywood. I also spent a weekend at Leleuvia patching the original canoe, which was "properly built". I bought the outrigger back to CATD to repair some major rot. Got the outside prepped, but the smell of rot coming out the holes indicates it is an exercise in futility. Hopefully it will last until we can get them a mini cargo proa. Why anyone uses plywood in the tropics is a mystery to me..........
Seta, the owner/skipper of the Drua dropped in for a look and a chat, offered me a sail from Leleuvia to Suva: 50 miles inside the outer reef. Interesting, knowledgable people and a nice coast, although navigation was a full time exercise. The boat was an eye opener. I arrived undecided, became a big fan regarding the suitability of this sort of project for cultural reasons. We were in a hurry so didn't get to shunt. Maybe next time, plus a charged phone to get some performance data. It certainly gets along and is the simplest boat of it's size I have seen. 4 wooden cleats tied on with poly twine and a large paddle for a rudder is the sum total of the deck gear. Huge fun and a nice break from boatbuilding. https://www.facebook.com/seru.zara.1/videos/556271862566041.........
We had a meeting with Waste Recyclers Fiji, who have generously supplied us with 1,200 kgs of empty wine bottles which are waiting to be crushed and used in lieu of sand in our mud brick production. They also supplied 1,000 kgs of unsorted, uncleaned plastic to practise on and figure out a way to make cargo boxes, plastic roofing tiles, floor boards, and concrete rebar. Only 999kgs of it left after the plastic melter/compactor's first trial which turned as much plastic sheet as I could carry into a 70mm deep, 150mm dia block. WRF set up a meeting with the Environment Minister to show him our waste plastic and glass solutions. I was invited to sit on a committee to discuss it further. The Nausori mayor was present, gave me a lift home. She is very keen on discussing a high speed electric ferry to Suva. Maybe once the shed is built..........
Visits from the Aus and NZ High commissioners. Nice people, we will see what comes from it. Also visits from representatives of sundry other Pacific Islands, some donors and others looking to partner with us and a couple of film crews. I was in a sailing film shot at Leleuvia by a Canadian couple. We took them for a sail in the Camakou, I explained what it was all about. .........
I spent a couple of hours glassing the rusted out bottom of a freezer in our new on site supermarket (the only one between here and Nausori, 10 kms and several thousand people away). Not exactly state of the art boat building, but it saved buying a new freezer for several grand..........
When it's raining (often), I play with the oven and scrap plastic. I melted and pressed some LDPE packaging plastic (I think it's LDPE, there's no mark on it) and pressed it into some 200 gsm pw glass. Worked a treat, the glass is transparent, indicating complete wet out/impregnation. The result is the same thickness and resin content (95% by weight) as hand laid 200 gsm fibreglass/epoxy. It is noticeably tougher as it bends without creasing or cracking and is impossible to tear by hand, unlike a single sheet of 200 gsm with epoxy. It was heated to 200C (less by the time I got it into the press) and 5 tonnes of pressure, a bit of a breakthrough for several recycling and waste disposal applications. I'm not sure how, or whether to use it for boat building, but have a couple of ideas to try when the PET foam arrives.

I also made a mould for pultruding plastic reinforced tow to make rods to replace steel rebar in mud brick and concrete construction. Failed miserably, so tried it as a compression mould. Better, but not viable for long lengths. An interesting learning curve. Next recycled plastic job is the cargo boxes..........
Henrik, who I worked with in the Marshalls sent some pics of one of the mini cargo proas (scroll to Nov 5) in Aur atoll. They added the rudder to replace the paddle and put a cabin on the ww hull to stop the copra getting wet. Hopefully, Henrik gets some performance data while he is there..........
It's getting warm and humid with sudden heavy rain showers as the cyclone/rainy season gets underway. My work day is slowly adjusting to 5 am-9 am on the boat, meetings, chores, lunch, office and snooze 'til 3, boat 'til dinner time. Not unpleasant once you get used to it.
CATD closes for Xmas, so I am going to Sydney for a couple of weeks. Steinar is already there. We both come back here in mid Jan. I'm looking forward to discussing boat ideas drawn in the sand on Manly beach with him. A cyclone while I'm away is likely, so I am doing what I can to make the boat safe. The big worry is the huge tree to the south west of the boat which, since the pine trees and hill were removed for the coffee shop is now exposed to sou'westers.

I got a small cut on my ankle which almost healed, then in the course of 2 days turned into a pretty messy superating open sore 50mm in diameter (pics on request ;-). Not an uncommon event here apparently and easily fixed with antibiotics, which I am now consuming.
