Design 1059 Scarlet OHara


I can tell you exactly what is going on in this image. They are working on a trim problem. Looking at the technical files it doesnt look like the trim was too bad. Tests were made with stern wedges and the issue was solved. Its somewhat surprising as the boat was tank tested at the Stevens Institute which included trim studies. Nevertheless here we are. Heres a speed and trim graph from the initial sea trials.


Its too bad. The boat reached a top speed of 32.5 knots but along with this speed came 4° of trim. Stern wedges were added and the result was a top speed of 29 knots and 3° of trim. Further modifications were made to the stern wedges and the issue was finally solved with a final top speed of 32.6 knots and 2.75° of trim.

The image at the top is clearly not Germany, where she was built by the Krogerwerft Shipyard. The image was taken in Miami where the final stern wedges were fabricated and installed.

Scarlet OHara was built for R. J. Reynolds, Jr., son of the tobacco magnate.

Here are the plans.

LOA 53-4"
