Right finally decided to do this build some ppl might think that is not the boat to start with and you might be right but seen a few ppl start with them and they seem to do it well, now with the help the boat will be 1.1meter in length and the tunnel width will be 5.5 inches, i have heard ppl make this a little bigger due to my length, what would you people say to this and what should i take it to 6.5inches, soppose this will give it better cornering ?

Next question what size ply should i use for the frame and skin please, ?

Hope this is all at the moment

the start of a good build i will tell you that
