The Gulfstar 43 MS (Motor-Sailer) represents a distinctive chapter in the evolution of accessible cruising vessels, a hallmark of its builder, Gulfstar Yachts. Designed by the prolific Vince Lazzara, this unique monohull blended sailing capabilities with comfortable powerboat amenities, aiming to appeal to a broad market of cruising enthusiasts. She is recognized for her solid fiberglass construction and spacious interior, making her a compelling option for those prioritizing comfort and versatility over outright sailing performance.

The Gulfstar 43 MS was launched during the formative years of Gulfstar Yachts, with production spanning from 1971 to 1973, and only 10 units built. The company itself was founded in 1970 by Vince Lazzara, a pioneer in fiberglass boat construction who had previously co-founded Columbia Yachts. Lazzara's vision for Gulfstar was to create accessible cruising boats, and the 43 MS exemplifies this early focus on motor-sailer designs. His design philosophy centered on an adaptive approach to meet market demands, evolving to a "balanced approach" in later models. Early Gulfstar models, while aiming for accessibility, sometimes faced scrutiny regarding workmanship, with interiors commonly featuring Formica and ballast consisting of iron in a concrete slurry, reflecting the manufacturing ethos of the era.
The design of the 43 MS, with its long keel and masthead sloop rig, was conceived to offer a comfortable platform for extended cruising. Its blend of sailing and motoring characteristics reflects a design philosophy that acknowledged the desires of many cruisers for reliable auxiliary power alongside the ability to sail, particularly in regions with lighter winds or when navigating long distances.
Sailing Performance and Handling
As a motor-sailer, the Gulfstar 43 MS offers a specific balance of sailing performance and comfortable motoring. With a displacement of 21,000 lbs and a total calculated sail area of 659.72 sq ft, its Sail Area to Displacement (SA/D) ratio is approximately 13.75. This relatively low ratio suggests that the 43 MS is not designed for blistering performance in light airs and will likely require a good breeze, or reliance on its engine, to achieve optimal speeds under sail.
The boat's ballast-to-displacement ratio, with 5,000 lbs of ballast in a 21,000 lb displacement, calculates to approximately 0.238 (23.8%). This relatively low figure indicates that the vessel may not be exceptionally stiff, meaning it could heel more readily in stronger winds compared to a dedicated performance cruiser with a higher ballast ratio. Its maximum draft of 3.5 feet, however, allows for access to shallower anchorages and marinas.
Conversely, the Displacement to Length (D/L) ratio for the Gulfstar 43 MS stands at approximately 156. This lower number, falling below the 200 mark, might suggest a more performance-oriented vessel for its length. However, in the context of a motor-sailer, it more accurately reflects a relatively long waterline for its displacement, contributing to a respectable hull speed of 8.39 knots. Anecdotal evidence suggests that the Gulfstar 43 can deliver "surprisingly good performance", though some owners have characterized the design as primarily a "power boat" with sails added, emphasizing its capabilities under power. Its long keel hull type contributes to a stable motion, particularly in a seaway.
Accommodations and Layout
The interior of the Gulfstar 43 MS is designed for comfortable living, reflecting its cruising intentions. It features a "spacious two-cabin layout" with a "large salon, a big functional galley, and loads of storage". The galley and dinette are typically "down" below the main salon level, which contributes to a "fairly roomy salon" on the main deck. This main salon often includes a complete lower helm station and convenient deck doors, enhancing its functionality as a motor-sailer.
While precise details on finish quality and materials for the early 43 MS specifically are limited, earlier Gulfstar models were known for utilitarian interiors often utilizing Formica. Over time, some older vessels might exhibit wear on interior finishes and frames, as noted in general reviews of Gulfstar boats from this era. Nonetheless, the fundamental layout prioritizes livability and space, making it a comfortable platform for extended stays aboard.
Owner's Perspectives
Owners of the Gulfstar 43 MS often praise its inherent robustness and substantial construction. The boat is frequently described as a "well built boat with surprisingly good performance" and a "solid boat worthy of consideration". This reputation for solid construction aligns with Gulfstar's broader legacy of producing viable "bluewater boats" for those seeking affordable long-distance cruising.
However, reflecting its motor-sailer design, some owner feedback suggests that its sailing capabilities, while present, are secondary to its motoring performance. One owner humorously remarked that the 43 GS was conceived as a "power boat" with a mast added, considering it a "Great condo boat but I would not sail it". This perspective highlights the expectation that owners should be prepared to rely on auxiliary power, especially in lighter winds. As with many older vessels, common considerations for potential owners include the need for ongoing maintenance and upgrades, particularly concerning original deck fittings and aging interior components.
