want to build a catamaran
hello, I would really like to build a small (maybe 8') catamaran. I have never built a full size boat but would like to start. I have no plans for one yet but I do have to windsurfing sails that I might be able to modify to work. I would like it to be fast, light, and look something like a hobie 16 or wildcat. has anyone seen plans for a boat kind of like this?

Re: want to build a catamaran
thanks! 9 ft looks tiny with a person in it! when I measured out 8x4.5' on the floor it looked big!

Re: want to build a catamaran
why is it that 14ft is the smallest? how fast is the one you built?

Re: want to build a catamaran
why are they not made smaller than 14'? I like the plans but I don't think i'd build a boat that large because I quickly loose interest in the things i'm building unless i'm working on them every couple days. that wouldn't happen. i'm 15 and don't have a job at the moment so it'd take a wile for me to get the parts, and then i'd get board of the idea and use them to build something else.

Am no naval Architect - but I suspect that below a certain size the catamaran doesn't work.......weight (including you!) vs power.
How about a trimaran? Could have a go a DIYing something up yourself - even if not actually building own Kayak (simply the outriggers?). 10 foot long......

Then don't take up sailing... it all takes a long time...
Or develop an attention span longer than an advert....

Another Wharram you might consider is the Melanesia 16 which is a proa. Probably cheaper than the Hita (my favorite though) or the CLC trimaran that DOJ suggested.

Or just get a used Hobie Cat and be done with it.

I love sailing and will never stop. when sailing something new is always happening. it's just that the figuring out everything i'll need to do and building the basic shape is fun, and then after that I want to build something else.

Re: want to build a catamaran
There was a fiberglass Hobie 11, that would sink with more than 130# of crew. It is just a question of displacement; if you want to float something that weighs 130#, you need to build something that takes the same amount of room as 131# of water!
Picture a long piece of foam with a triangular cross section with the ends tapering to a point over a two foot length. They look like a very tall three-sided pyramid. If you l;ay them head to toe, they will together displace the same amount of water as a two foot length of untapered hull. The total displacement of your two hulls is now pretty easy to calculate, and the result would be a useable approximation of a hobie hull. You do the math!
