Works very good. Makes it easy to keep good luff and Leach tension in the sail. Quite tricky to get it to catch, but easy to release it, and that is the important thing.

You could say the same thing about the first car Mercedes, but now I bet you drive or using one. In short you are a moron and will stay that way. Good luck to you.

Jacknife is tucked up in the shed at the moment and I am making a fridge for the galley and doing some paint touch ups. Probably won't hit the water again until next January. Then I will post some more videos.

Ian Aitken Thanks for responding. Will there be a guide produced on your building journey for others or plans.

@@timothyrussell2409 I have had several similar requests so perhaps I should make some effort in that direction. I have a build diary and a few hundred photos of the build so it would be possible to put it into a book form. Not plans as such but just a record of how I built the boat. Don't hold your breath but yes I will get around to it one day.

Thanks Ian.Im amazed Rob hasn’t tried to organize something.A downloadable story or guide as your boat has so many good ideas for a normal sailor interested in a proa.I hope you find the time.All the best.Tim.

@@ianaitken1136 Interiour space is the weakness of proas and yours have a beautiful and cozy interiour, and spacious deck. I think that this specific design deserve a plan, especially for those that want a proa for cruising in more confort. Beautiful job! Congratulations!

Hello Peter, the boom is made of carbon tubes and is in 3 parts. Each part weighs about 8 kg so is easily manageable to assemble and disassemble. It plugs into a tabernacle device to raise it as a crane jib. Then after the mast is plugged in it is lowered and taken apart to be positioned on the mast.

No sorry, the linkage is just a stainless tube with marine grade rod ends. I sorted out the geometry on a model before making the full size parts. When I am sailing next summer I will video a shunt and show how the rudders flip around 180 degrees and how the tillers are used.

I think it will be strong enough. It is 2mm thick 316 stainless and most of the stress is in plain tension. But time will tell. It is very easy to design something that will never fail, just make it many times stronger than needed. Trouble is that also makes it many times heavier than needed. High performance multihull boats should be designed to be just strong enough, then only one more thing should be added, (more lightness!)

Sorry bout that I've got a cold. But trust me you are not missing much.

Hello Robert, Please call me Ian, in New Zealand we don't do formalities, even if a Kiwi bumped into the prime minister on the street we would just address him/her by their christian name. Sorry no chance of me producing build plans. I am a retired mechanic/farmer/engineer and built Jacknife as one of the projects on my bucket list. I have extensive notes, calcs, build diaries and photos that I may put together in electronic form sometime in the future. A competent builder should be able to follow them. Have you checked out the specs on the Harryproa site. Just search Ian Aitken.
