How much harder to make the rounded hulls? are we talking another day in the building or another week? That boat is fast out of the water! RG do you have plans on the building of it yet.
The round bilge version would have to be done as a strip planked foam hull, then glassed and faired, in some ways quicker and in others slower, I'd guess that with 2 people a single cat this way is about 6 weeks work (500 hours approx) if your reasonably experienced. For a beginner I'd add another 200 hours.
