Mike,
This sounds awesome, and I'm guessing, but it sounds to me like the 70 might be a scaled-up version of the D - just shy of three times as long - which would mean a VERY wide beam (nearly 24 feet!) compared to other boats that size...but also, it might ride so high on the water, and yet stay so vertical during beam reaches due to the huge area, that it will perform like a cat, with the safety of a monohull! The comparison to the existing D boat would be to gather true "scale-up" expectations!
In any event, she is more like the 26D (semi-planning) underwater than the 26M (planning).
Okay, enough speculating - please explain the above statement - are you saying that the D (and consequently the S) are actually "semi-planing" hulls, and not true displacement hulls? Does this mean that there is a chance of exceeding hull speed in the D/S models? Thanks!
PS I think Mike just likes us, and that's why he asked one of us for a D boat to use...no reason to do all the title transfers, registration with the state, etc. just to test a boat!
