New builder

hey im a 16 year old guy and was looking around at some boats to build

i decided to build the smallest budget boat that i could.I was thinking of building a small 7ft hydroplane not for racing but to bring to lake saranac in NY and was wondering whats a boat like this could handle and if there were any good free plans. Also other than lumber what other materials would i need to purchase and whats the minimal i would have to spend?


or ... if this is a bad idea alltogether

 

Yes! But that didn't stop the rest pf us!
