Similar to the later BRISTOL 24. The CORSAIR, besides the 'standard' version (twin settee with V berth forward), was also available with a convertible 'Dinette', with a galley on the opposite side amidships, and a single quarter berth aft. An inboard engine was available as an option.
Boats called Bristol have lead ballast. Those from Sailstar, concrete. Ballast was always meant to be 3000 lbs. even though it erroneously appears as a lower number in some documentation. (according to Clint Pearson the builder).
Thanks to 'Bristol 24' for providing corrections.
