Description:

The Mainship 390 Trawler is a purposeful looking boat the high bulwarks and heavily flared forward hull sections make her instantly recognisable. With a ‘cods head’ hull shaped she carries her maximum beam well forward creating a shoulder with her flared bow creating an easier motion in a sea way whilst repelling much of the spray. A comfortable displacement cruiser she will comfortably cruise at 8kts. The accommodation provides comfortable living for two couples with two double cabins. Her interior design with an open plan saloon using moveable items of furniture was arguably well ahead of its time on the late 90’s.
