Elvstrom 1/2 Ton (Bes / Elvstrom 32)

Description

The Elvstrøm 1/2 Ton (also known as BES 1/2 TON) is a classic IOR Half Ton class racing sailboat designed by legendary Danish sailor Paul Elvstrøm in the early 1970s, based on his yacht Bes that he skippered to victory in the 1972 International Half Ton Cup in Marstrand, Denmark—marking it as the first fractional rig boat to win a ton cup in the IOR offshore racing era. Built in fiberglass with a fin keel and skeg-hung rudder, production was limited and occurred primarily through Chantier Gouteron in France starting around 1972–1974, with only about 8 boats ever constructed, making it a rare and sought-after vintage classic today. It features an innovative 7/8 fractional sloop rig (advanced for its time), good performance with a reported sail area of around 349 ft², basic cruising accommodations including berths for 6–8, a head, small galley, and inboard diesel engine options, blending competitive racing prowess with overnight capability.
