We have two versions for this particular design, the difference being that one design package is supplied inclusive with the purchase of a
pre cut construction package from ATL Composites Australia (Contact us for kitset details and we will put you direct contact with ATL for pricing
the complete or partially complete kit).
Or Alternatively we will supply seperate, this design as a package that allows a builder to custom build the vessel in a conventional manner.
This allows the builder to produce this vessel from self made or pre made composite panels as they find necessary and economic to do so.
Kitset Dwg. files supplied for main shell and transverse shapes.

stitched glass, foam cored composites for both shells and internals. Full size dwg format files are supplied for both
