Wavelength 30 Design Notes

Immediate Release

Paul Lindenberg who is recognized for his extremely fast boats such as the Lindenberg 24 and 26 has teamed up with the W.D. Schock Corp., Florida division, to re-introduce Paul's Lindenberg 30, now called the Wavelength 30.

The name "Wavelength" comes from the first of the Lindenberg 30's which compiled a very impressive racing record in the Southeastern United States.

The new Wavelength 30 is an extremely large 30 footer as evident by comparing its sail plan, waterline length and hull lines.

The hull is designed for optimum performance and is free of the distortions associated with the IOR rule. With its nearly 50% ballast to displacement ratio, the Wavelength 30 easily handles even the most severe conditions.

The hull and deck are cored using proven end-grain balsa wood. Areas on the deck where winches and other hardware are through bolted are reinforced with marine grade plywood to better absorb the compression of the bolts. The deck is mated to the hull, sealed and through bolted along the entire toe rail. Structural bulkheads are bonded to the deck and hull to add to the total strength of the design. Down below the Wavelength 30 the weight distribution is located at or near the center of effort.

The engine, a BMW 7 horsepower diesel, is located directly above the keel bolts. The engine box triples as a backlit navigators station and as a dining table when the folding side leafs are locked into place.

The interior volume of this boat is truly astounding as the interior working and sleeping are as big as most 40 footers.

SA/D Ratio is the Sail Area/Displacement Ratio.

This ratio indicates how fast the boat is in light wind. The higher the number the faster the boat.

* Cruising Boats have ratios between 10 and 15.
* Cruiser-Racers have ratios between 16-20.
* Racers have ratios above 20.
* High-Performance Racers have ratios above 24.

SA/D Ratio for a Wavelength 30 = 20.4
SA / D = Sail Area / (Displacement in Cubic Feet )2/3

D/L Ratio is the Displacement to Length Ratio.

This indicates if the boat is a heavy cruiser (results greater than 325) or a light displacement racing boat (results less than 200).

D/L Ratio for a Wavelength 30 = 151.6
D / L = Displacement / ( 0.01 * LWL )3 (Displacement is in long tons)

Angle of Vanishing Stability.

One of the best predictors of ultimate stability is the "angle of vanishing stability" or the angle to which the boat can heel and still right itself. A dingy will have a stability range of about -80 degrees, an inland water boat should have a stability range of -100 degrees, and an offshore boat of at least -120 degrees. Boats which have a stability angle of less than -140 degrees may be left floating upside down once capsized. Boats with a higher angle will usually right themselves

Angle of vanishing stability for a Wavelength 30 = -131.99

Dr. Carl Adler is an avid sailor, devoted web junkie and a physics professor for East Carolina University at Greenville, North Carolina. You can use his Sailing Calculators “to look up sailboat parameters in a large database of boats, or enter your own boat and compare to the others. In addition, for any boat you can calculate a set of quantities that will help you measure how it will perform.”
