John,
I thought about it some and you may be right but I think it has more to do with speed. Almost all full disp hulls are limited to hull speed. At times when I leave the harbor and rev up to " cruising " speed I look at the water and can't belive how slow I'm going. Most guys just couldn't stand it. Takes us almost a full working day to get to Ketchikan .. but it takes only 5 gal. The ferry fare is now $100. RT one person so we go much cheaper on the Willard and then we stay on the boat and save $100 a day there too. But it takes two days to come and go. With your Mainship we could come and go in the same day but it would probably cost more in fuel than the ferry. There are some boats that function as a disp hull at disp speeds and at semi disp speeds they are much more effiencent than TTs, Nordics, GBs and the like. These boats were designed by William Hand about 1910 when engines were very low on power. They switch roles by taking advantage of the change in pitch attitude. Google search South Hampton Marine or Handy Billy to see a modern version of his hull form. Brilliant design. BUT .. these boats will not plane above a SL ratio of about 2.25 .. about 12 knots for a 32' boat. These are the kind of boats I predict will emerge on the market but not untill fuel gets more dear. As is obvious from earlier discussion, box style hulls will prevail a bit longer.
