I am willing to give you a slightly biased opinion. I am the designer of the Moloka'i Strait motoryachts, and one of the partners of Moloka'i...
Active trim tab: You don't need one, generally. The helmsman sets the trim tab angle for the conditions at hand. For any given sea state and...
The most obvious reason that you don't see stabilizers on planing yachts is that the loads on the blades and their stocks would be way too high at...
Tri-star makes some valid points, but he seems to present it in a way that suggests engineers "forget" about the shear loads within cores. This...
The best vocational course that I know of is The Landing School (www.landingschool.org). It is a residential program in Kennebunkport, ME,...
Yes, that happens more often than it should. Mostly I would bet that you could trace a soaked core back to a poor bond between the core and the...
If it were my boat and I wanted composite construction, I would go cored. I am also assuming that this is a one-off, not a production boat. The...
Welcome Newbie, A motoryacht is a generic term that can apply to any size, style, of function of a yacht, from slow speed displacement yachts to...

You have to be very careful in comparing the motions and performance of hard chine and round bilge hull forms. Certainly, for the same length of...
Your choice of hull type really depends on what you want to do with it, and how fast do you want to get to where you are going. Planing hulls are...
Kelly, There are five things to look for to determine the capabilities of a semi-displacement vessel. Speed-length ratio, of course, is the...
The Independence 45 is a semi-displacement boat. It was built by Independence Cherubini Company, now out of business. I did the lines extension...
Quality and tolerance, of course, are two different things. The marine industry does have its standards, but it is no where nearly as highly...
There are indeed many similarities between the marine industries and the aerospace industries, particularly when it comes to aerodynamics,...
Skiffy, If there is any constant in yacht design and engineering, it is that there is no lack of ideas for new technology. They are not hard to...
