Wooden ships comments on this 37′ Robert Clark Sloop

A typical Robert Clark design of the period, following the same principles he adopted for his previous yachts.  Long overhangs, quite narrow in the beam and deep draft gave his boats good performance bringing him much success and recognition on the racing circuit.  This particular boat was no exception, competing in the 1952 Transatlantic Race with Clark in the crew, and went on to compete successfully in offshore events well in to the 1960’s.  A quick read through the Yachting World Annuals of 1950-51 and 1951-52 shows she was commonly at the head of the fleet, accumulating points in nearly every race and proving very successful, along with her near sister ship owned by the Royal Engineers regiment.

Bought by the present owner in 2002 and sailed locally around the English Channel.  Several significant amounts of work have been carried out in the present ownership to help maintain and upgrade the boat, including a new engine, strengthening of the mast step and rebuilding the area around the aft end of the cockpit and counter.


Built by Thornycroft in 1950 to Lloyds100A1 and kept in class until the mid 1970’s.


Planked in 7/8” mahogany above the waterline and teak below, fastened with copper nails and roves to steam bent 1.5”x 1.25” Canadian Rock Elm timbers at 7” centres.  Larger scantling frames in the area of the mast step, all bronze screw fastened hood ends.


Galvanised steel strap floors with new oak floors fitted in way of the mast step for strength.


Lead ballast keel fastened with Monel or S/S keel bolts, all replaced approx 15 years ago.


Two large ring frames made of galvanised steel to Clark’s well known design to add strength to the mast step area.  These run up the inside of the hull, under the deck and up the coachroof deckhead.


Deck is yacht laid teak joggled to a king plank screw fastened over the original T&G cedar deck.

Large section beamshelf all round with galvanised steel hanging knees and a small clamp for extra strength.

Coachroof coamings have been replaced in marine plywood sheathed with epoxy and finished in white gloss paint.  Coachroof deck of epoxy sheathed marine plywood, finished with deck paint.

Varnished teak forehatch on the coachroof deck with scrubbed teak grab rails either side.
