Hey Gil ! Sounds quite admirable of you to attemt to build a Kayak without any plans. If cash is a problem I would strongly suggest that you down load some "free" plans that can be found on the Net. Don't waste your time and what little cash you may have on something that will probably be highly inferior boat. Designers put MUCH thought,expertice and time in designing a boat. Unless you have some kind of exp. in this area your "guess" could be a huge waste of time money and effort. Nick has free planes right here for a stich and glue yak, I would strongly suggest you start there. And feel free to hang out here and ask questions. Good Luck.
