Let me start by saying I'm new to the world of yacht design so my questions will probably be simple if not annoying to the true professionals on the fourm. As to the title of this thread, I'm an astrophysicist by trade but must admit that there are nuances of yacht design that are well beyond me. Background: I'm working on my first design for a "down easter" style yacht, and the plan is to produce an extremely efficient hull design that can hopefully cross the pond without sinking or getting beat up too bad in big water. Current working specs: 60' LWL 12' Beam ~3' draft ~35,000lbs Disp. Now to my "newbie" questions: If i'm considering wood/epoxy construction (should I be at all?) what's a reasonable hull thickness? Should I be worried about how high the free board and superstructure are on a yacht this narrow for roll? If so how high is too high? Will have a couple other questions after I upload a pic for the members to judge my level of lunacy from.
