Excerpts:

Classic Dutch Yachts and the Real James Bond
By Dave Gerr

On recovering, Minshall returned to his sailing and spying. He was reporting to Special Branch of British Naval Intelligence, and directly to none other than Ian Fleming. (Yes, the creator of James Bond.) Minshall's designation number was, you guessed it, 007! His gun was a Walther PPK carried in a shoulder holster, with a back-up Beretta .25 concealed in his pants. A top marksman, Minshall was also both a judo and karate expert. It's almost certain that Merlin Minshall was one of Fleming's inspirations for James Bond.

Orca3D User Tip
By Bruce Hayes, Principal Naval Architect, DRS Defense Solutions, LLC

This article is not to give instruction on what the shape of the heeled waterlines should be, but rather how to find them. First, it's important to understand that simply rotating the hull and cutting waterlines will not give the correct result, because as a hull with a given weight and center of gravity (CG) heels, it will also trim and move vertically (unless it is a rotationally symmetric shape such as a cylinder). We need to find the underwater shape of the hull when the weight and buoyancy, and CG and center of buoyancy are in equilibrium. Orca3D's hydrostatics and stability calculation has two fundamental modes of operation; in the first, the user specifies a flotation plane with a combination of sink, trim, and heel, and Orca3D returns the displacement and center of buoyancy (as well as other parameters). In the second, the user specifies the weight and CG, and Orca3D finds the equilibrium flotation condition (sink, trim, and heel).

Learning from a Tragic Capsize
By Dave Gerr

After sailing out to watch the fireworks on July 4th, 2012, on LongIsland Sound, the 34-Foot Silverton, Kandi One, capsized with 27 people aboard. Tragically, three of the children aboard lost their lives. The general feeling among marine professionals was that that having so many people aboard a boat of this size was excessive and was the underlying cause of the capsize. It is important, however, to analyze the event systematically and see if hard numbers confirmed such gut feelings. At the request of Soundings magazine and using vital information from Eric Sorensen (and with valuable input and review from naval architects Eric Sponberg and Steve Daizell), I set out to do just that.
