Alien III design

With two 8×4 sheets of plywood, this dinghy could be 10-11 ft long at the price of some scarfing. The width could be a bit more than 4 ft which is good, not too wide, not too slim A two chines configuration with a flat bottom and a forward transom lead to less curved panel development allowing better use of the ply.

The final project was elaborated with Turbocad, optimized, and very accurately drawn to avoid the job of full-size lofting.
Once the definitive line plan is drawn, the hull’s panels were decomposed into triangles to do the development. Tests showed that the accuracy is better than 2/100″ on overall dimensions.
