    I don't know many designers that would recommend going across the oceans in folding cats.

    Not saying it can't be done, but you need to design it for serious conditions. Way outta my ballpark.

    How much would that cost?

    My budget is 2000h

    Haven't done the math yet, depends a lot on range you want though, maybe 50nm is enough on electric, rest under sail...

    Well it is experimental, and most likely you need to apply high lift devices, below lift off for 10kt:

    Well the idea is to only be a like 5 hours on the way, then stop for dinner(recharge battery) then another afternoon sail...

    Bolted connections can be made strong when designed properly, the whole folding is just to make folding time quicker at the dock, so when unfolded all joints wil get bolts inserted to make it stiff enough, thats at least the idea. The two floaters will also be bolted properly on so that it will help to stiffen the hull.

    I am trying to do the catamaran calculations now:
