Seamaster 813

This craft was in production from 1972 until 1981 when Seamaster stopped trading. Nearly 400 boats were produced in that period. This craft is a more modern variation of the popular Seamaster 27. The hull and superstucture were used by many other companies including Aardvark of Canvey Island, Aire Marine of Windsor and Bounty Boats. Accommodation offers 4 berths in 2 separate cabin. The forward cabin has 2 single berths in the bow and the saloon is separated from the forward cabin by the toilet compartment which spans the width of the boat. The saloon which is aft of the toilet compartment has a dinette which converts to a double berth and a large galley opposite. The medium V to shallow V hull has a long shallow keel. The craft is an ideal river cruiser but is capable of fair weather estuarial or coastal work. Some boats were fitted with single Volvo petrol engines and outdrives but most were fitted with inboard diesels or petrols which are better for handling on the river.
