SHEARWATER ex GLACIER STAR is a classic Seaton design, finished to the highest structural and aesthetic standards. Her clean lines and distinctive sheer prompt admiration wherever she travels and her living quarters provide classic and comfortable accommodations for a ship's complement of four for long range cruising. She is outfitted with the best of equipment, with all vital systems redundant for safe, comfortable offshore passages as well as the amenities and room for stores for extended living aboard in remote ares. A yachtsman's trawler, SHEARWATER has enjoyed wonderful maintenance with constant upgrades including two new continuous duty John Deeres in 2009.
