RE: Why semi-displacement (or semi-planing)?

Also, Dashew's boats have little to do with what's out there in the "production" ranks.

Dashew is concerned with VOYAGING , not 1 in 10,000 or so is looking to do real ocean work.

Production boats are to be MARKETED , if its great as a condo , with the bride , 90% of the job is done.

Efficency is how fast the bucket gets SOLD , hardly how it performs.

RE: Why semi-displacement (or semi-planing)?

Knight and Carver in San Diego built a demonstrator for the M-hull and they run it around the bay from time to time. It is amazing to see it scream along while producing virtually no wake.*

Here's a link to*one pretty good article, there are many more for the searching.*

RE: Why semi-displacement (or semi-planing)?

Oh gosh, is this Bat Boat a FD or SD? There is on off-shore Swedish racing design that is loosely similar and has enjoyed great success over the past decade. The interesting question for the Bat Boat is rough water ( +3" seas) ride. Catamarans and the old Chrysler tri-hull tend to*pound and bang*in heavy weather as compared to a mono-hull. Once the wave height reaches the Cat deck, some interesting noises and pounding occurs. Would this issue limit the Bat Boat's popularity? With government money paying for this study it will be fun to watch. By looking at the Bat Boat's*soft chine it must be FD.
