Wooden Ships Comments on this International Six Meter GBR31
International 6 meter racing yacht SILVERVINGEN built to Rule 3.  Designed by Tore Holm and built by Hagerstens Batvarv, Sweden in 1939.
At the outbreak of WWII, Silvervingen was laid up and not sailed until after the war.  Tore Holm designed a cruising interior and small coachroof for her, but she went on to race successfully throughout the 1940’s and 1950’s under various different names.
Purchased in 2004 by the previous owner, Silvervingen was in a sorry state and needing a thorough rebuild.  Over a 9 year period the deck was removed and the hull slowly put back into shape to reinstate the original sheer line.  The wooden keel was replaced and new ballast keel bolts fitted.  Over 70 frames were replaced in streamed oak and all the galvanised plate floors were renewed.  A new deck was fitted with 12mm plywood overlaid with Oregon pine.
She was then sold into UK ownership and a major period of upgrading commenced to optimise the yacht for racing in the 6m series.  The basic boat was in excellent condition and needed little structural repair, but the rig was renewed entirely, the deck hardware layout professionally re-designed and all new electronic systems fitted.
Top professionals have been engaged at all stages of the design and build to ensure the hull, rig and systems are as good as they could possibly be.
Now under UK flag, this 6mR yacht is sailing under the sail number GBR31.  The boat was raced in the 2023 6m Worlds and finished 3rd overall in the Classic Division.  This is a yacht at the top of her game, in superb condition and fitted out to a supremely high level.
Available to view as part of an open day of the yard near Southampton on 17th August 2025
