Quicksilver - Design 2158


I’ve been doing some research on this boat. It looks like we used the Lines and General Arrangement from an earlier design. The plans for design #2120, Gunfleet of Hamble were used for #2158, but with a different deck geometry and layout.

Interestingly #2120 was designed for aluminum construction and this boat was designed for wood construction. The statistics look pretty identical. The only major difference is the additional sail area that Quicksilver carries, and to handle that 1,450 lbs of internal ballast was added.

Reviewing the Lines Plan it also looks like the sheer was changed forward, adding more spring. This was probably done since Quicksilver was a wedge deck and Gunfleet was not and in addition the forward sections were filled out and the Lines and Table of Offsets adjusted accordingly.

Quicksilver is an Admiral's Cup Racing yacht. She was built by Brin Wilson of New Zealand and launched in 1973.
