Historical:

The one and only 510 built, named after Raymond Hunt’s wife Barbara.

(C. Raymond Hunt) “In 1945, I designed the original “510” class yacht for myself as a logical development of the “210”.

Launched in December 1945 as a racing and weekend cruising yacht. She is built with no structural keel, and is constructed with two longitudinal trusses on oak floor stiffeners extending to the after end of the cockpit to the mast evenly distributing the stresses of the rig and keel.

Low wetted surface area with a separate rudder-skeg / bulb fin keel, a concept Raymond Hunt embraced long before Lapworth or Giles, should prove to be a spirited performer, with comparable speeds of 8 meters and Q-boats.

Known Racing History:

1949 – NYYC Cruise – Beat the 72’0″ Yawl “Bolero” boat for boat, with Raymond Hunt and his wife sailing against a full paid professional crew on board “Bolero”

In 1975 C.J. Frankham, esq, Aukland, New Zealand wanted a inexpensive high performance owner operated yacht and decided to have CR Hunt and Associates revise and update the 1945 drawings of the 510 class yacht that Ray Hunt built for himself. The design of the hull was left basically unchanged, but the sailplan was updated. The main was increased 35 sq ft to 335.8′ P = 39.5′ E = 17′ and the jib was increased to measure 215 sq ft I = 37.5′ J = 11.5′ The accommodations were also updated to include 2 berths and settees with a head and small galley located in the companionway for the additional headroom.

Also Modified from the original boat is the deck plan. A self-bailing cockpit replaces the split-cockpit arrangement. The Interior plan, that accommodates 4 people, has been changed to suite the owners requirements.

Although the 510 design was revised for construction to occur in New Zealand, it was never finished. A reported fire in the barn which housed the owners business and the 510 under initial construction were all lost.
