DESIGN AND DESIGNER
The Coastal Flyer is built on the proprietary Gerr-Vee hull form, modified for the use with jet-drive propulsion. This is a true vee bottom, planing-hull shape, but it is neither a deep-vee nor a modified-deep-vee. The hull has been under development by Gerr Marine since 1989. It was engineered to improve the comfort and sea-keeping abilities of vee-bottom planing hulls. Gerr-Vees are no faster for a given horsepower than conventional hulls, but Gerr-Vees are very soft riding and have excellent directional stability in a following sea. In addition, the hull is very stable offshore at low speed or at low speed or at rest, due to its unique tunnel chines
Gerr-Vee hulls have been used on several different vessel designs over the 12 years, and all have exceeded expectations. A review of a 66-foot Gerr-Vee hull from January 2001 Yachting Magazine explains as follows: Simply described it is an inverted bell flanked by tunnel chines, and it gives the softest ride I have ever experienced at speeds up to about 30 knots. Beyond that speed, I have only hearsay to reinforce my opinion, but I trust my sources. Actually soft is a "lame" description of the ride quality; it is more complicated than that. I have to call it magical. It does everything so well, short of making the boat go faster, than it would atop other bottom shapes. Gerr is first to say the design elements in the bottom are not new, but the way he used each one and combined them is. He starts with bell-shape sections, quite narrow, steep and deeper than normal in the bows, broadening amidships, then flattening on the run. At the transom, the narrow part of the bell is squashed flat, providing an effective planning surface.
The coastal Flyer takes advantage of all the past on-the water experiences with the Gerr-Vee, Bringing the form to the next level.
