A Tank Test Model For A Proposed Design Of The Twelve Meter Yacht WEATHERLY
Stephens Institute; American, 1961
This model, built for Philip L. Rhodes, as a proposed design for the America's Cup defender WEATHERLY. The hull of the model is built up in wood. The interior of the hull has been hollowed, and the exterior of the hull has been shaped, faired and finished to a race finish. On the leading edge of the bow, down to the bottom of the keel is sand which has been glued in place. The sand was used to create a disturbance to the laminar flow, so the flow below the waterline could be more easily documented. The exterior of the hull is marked with No.:2095 which is the identification for the Davidson Lab at the Stephens Institute where the model was tested. The model is built to the scale of 13.3" :1' and the interior of the hull is marked July 20 1961.
60¼ x 10½ x 11½ in.(153 x 26.7 x 29.2 cm.) model dimensions.

The yacht Weatherly, which sucessfully defended the America's Cup in 1962, was designed by Philip L. Rhodes and built by Luder's Marine. While not the final design, this hull shows the subtle differences which yacht designers made during the design process to gain the extra 1/4 knot of speed. The most apparent difference in this model is difference of the bottom back edge of the keel. The Stephens Institute, was the primary towing tank where yacht designers tested new hull designs for yachts. Most of the models tested from the late 1950s through the 1970s were made by a few builders specified by the Stephens Institute. This way they could preserve the standard of quality and scale of the models tested for consistent results.
