Broker's Comments

This quality vessel from Oyster has served the current owner (since 1987) well on many ocean crossings taking heavy seas in her stride, including Mediterranean, 4 x Trans Atlantics, South to Venezuela, North to Canada and the Great Lakes and mostly everything in between. She was kept and sailed in the fresh water Great Lakes for approximately 18 years. One of only a few with a sloop rig, she has been continuously maintained, updated & improved and has proved herself a comfortable, sea worthy boat in all conditions. Sadly, the time has come to find her a good new home. British Part 1 Registered. These boat details are subject to contract.
