Constructing the Base:
The job of the base in building an ENVIBOATS design is quite simple. Provide a large, stable platform on which to erect the jig. (We provide a diagram and material list of the base with our kits.)
It should be roughly the size of the maximum beam and the LOA (Length Over All). Take into account the standard sheathing size is 4'x8'. So, if you are buiding a 27' boat, go ahead and make the base 28' long as this is perfectly divisible by 4'.
