Gulfstar 43 Tri-cabin
Description
The Gulfstar 43 Tri-Cabin refers to the three-cabin (tri-cabin) layout variant of the Gulfstar 43 series, a robust American bluewater cruiser designed by V.S. Lazzara (Vince Lazzara) and built by Gulfstar Yachts (USA) from 1976 to 1978, with around 80 hulls produced across configurations (including sloop and ketch rigs; tri-cabin setups are less common but appear in some center-cockpit examples with forward V-berth cabin, saloon, and separate aft cabin plus an additional midship or convertible sleeping area for three distinct cabins). This heavier-displacement, long-keel design prioritizes comfortable offshore cruising and liveaboard suitability over speed, featuring a center cockpit for protection and easy access, solid fiberglass construction (no widespread blister issues in maintained boats), generous interior volume with good storage/headroom, and stable, sea-kindly motion—ideal for extended passages or family use, though it motor sails well with its inboard diesel.
