Gulfstar 53 Sloop
Description
The Gulfstar 53 Sloop is a rare variant or conversion of the Gulfstar 53 Motorsailer (MS) series, originally designed by V.S. Lazzara and built by Gulfstar Yachts in Florida, USA, from 1971 to 1975 (with ~27 hulls total in the primary production run, mostly as masthead ketches; true factory sloop-rigged examples are extremely scarce, and many "sloop" versions result from owners removing the mizzen mast for simplified handling, added deck space, and no notable loss in performance under sail). This heavy-displacement, beamy fiberglass motorsailer prioritizes comfortable, long-range cruising and liveaboard capability with its shoal-draft fin keel (great for shallow anchorages like the Bahamas), powerful inboard diesel for reliable motoring (often 100+ hp, with high fuel capacity in some refits), and expansive interior volume (multiple staterooms, full galley, heads, raised saloon elements for light/visibility, and good storage/headroom)—suited for extended coastal/offshore passages or family use rather than high-performance sailing. The sloop rig (when original or converted) offers simpler sail management and potentially slightly better upwind efficiency compared to the standard ketch, though the boat remains motorsailer-focused: slow to accelerate in light air, modest pointing ability, but stable and sea-kindly in breeze/heavy weather with a smooth motion and proven reliability when maintained.
