Excerpts:

Book of Dave Martin Designs
by David Martin
He paused a moment as he confidently felt the firmness of a Colt 38 automatic firmly tucked in his shoulder holster. As he proceeded unnoticed toward the Atlantic City ghetto, he gave a sidelong glance at his gleaming new custom Packard, left purposely at the station so that everyone in the town would think he had remained in New York for the night. He couldn't help but chuckle at the sight of it. He had banged his head about a month ago and then ordered his chief boat builder to remove the Packard body and replace it with a new Martin designed body with full headroom. It was the only full headroom Packard in the world.

The "BMS Power Skiff"
by Jerry D. Burkett
The BMSLong.Step™ concept was a result of being intrigued by the Westlawn Text 117, page 25, which discussed the concept of the "ideal beam for different speeds." The total residual resistance of the boat with the "low chine beam which is unrealistic in practical terms" is substantially lower than the full beam width boat and the porpoising margin increases. The David Taylor Model Basin work referred to in the text was led by Eugene Clement. He has since retired but gave me a copy of the test reports that proved to be essential to my development work. Other essential pieces were the Daniel Savitsky porpoising limit analysis and his performance prediction analysis including the calculation of CG rise, which he kindly explained. The idea on how to take advantage of the ideal beam concept came to me in 2001 and the patent was awarded in 2007.
