Re: Are Boats Built in the 70's Just Too Tired
After the Annapolis Boat Show I trashed the Beneteau Sense. Although it's not my taste, the design tools available today produced almost a full length chine that reduced the ideal healing angle by about 5%. I found when I focused on current design advances, I was impressed by the results produced by computer aided design. So many of the weak links were being minimized in even the production boats. It's become easier to produce a better boat for less. That's not to be confused with build quality though.
My Wayfarer, designed in the 50s, had hard chines. Even though my boat was fibreglass, it was designed to be built in plywood and the chines are a result of joining 4 sheets of ply. They did indeed make it a stiffer boat than others in its class.
My point is that you hardly need modern design tools, hard chines have been in use for ever.
