Great job. Dont know anything about sailboats and windsurf masts.. But if the mast is 50 mm at the buttom, and it needs to be able to rotate. You could put a 50 mm stainless ballbearing there in a support structure . Inside the mast you could glue a 40 mm stainless tube. Sticking 20-40 cm out of the buttom. And ending in a mast foot with a 40 mm bearing.. That way you would not need that high mounted support.
@@arnauddecotterHello! What's wrong with this design? Insufficient strength or size? And what is the outcome of this project? It seemed to me that the diameters were not 80 and 40, but 90 and 50, did I guess right?
@user-th4jk2jx8b I honestly can remember. But I would not do this again out of pvc.. as it's will break under too much wind.. and aluminium frame would probably be better.
@user-th4jk2jx8b there was nothing wrong with the design only that the sail cannot fulling rotate like on a surf board.. also only use the center board.. no rear fins. Otherwise rudder won't be very effective
Well that depends on the wind.. I think i was around 5 kts.. the pvc eventually had a crack due to the sail catching on the side poles.. but the concept was good.
Great idea plastic tubes !!! looks like production type...
really good job!
looks much smoother ride than the first test.
finally there's a purpose for those old mistral boards XD
Thanks.. it did work great until I put fins at the back.

Great invention! Very inspirational sir. Great job.
You have instructions? or more photos of this?
@@HuyNguyen-ue3fk , no.. but if you facebook me.. I can help. Facebook. Is chr decot
Pretty cool concept is the structure all mave from standard schedule 40 or 80 PVC from the hardware store like Home Depot?
Yes .. but i would use wood next time or aluminium.

@@arnauddecotter Do you mind if I want to repeat your design with my own changes?) If it works out, I’ll send you a photo of the result)
Great idea. What is your top speed?

@@arnauddecotter 5kts in what sort of wind?
@@bamboozle999 mild wind
are those surfboards or SUPs?
Surfboard.
how long are the surfboards?
@@gel0712 almost 3m.. long time ago now. Old school board.
They look like windsurf boards to me, am I right?
Super
quem tem criatividade faz qualquer coisa.
Excellent!
Thank you. Concept was good..
@@arnauddecotter I have been 'stealing with my eyes 👀 '!
@@russellmackenzie2689 don't use rear fins on the board.. otherwise you won't be able to steer..
Send me your email address and I'll send you pictures of how mine is turning out.
