Timbo, it could be done, but easy enough to design dedicated cat hulls. The time consuming to build, or expensive to buy, part is the foils, more than the hulls now-days. And I'm not convinced T-foils are quicker on cats. L'hydroptere dihedral style is the way to go, simpler all-round and probably faster too.

Only problem with CNC is that the larger machines are rarer. We were lucky that the moth fit perfectly on ATL's standard panels and cutter. Larger hulls would require scarfing, but ATL have a system for that too.
