Gulfstar 36 MS Information, Review, Specs

Sailing Performance & Handling

As a dedicated motor-sailer, the Gulfstar 36 MS is not intended for the racing circuit or high-angle upwind work. With a long, shallow keel and a heavy displacement-to-length ratio, the boat is most comfortable on a reach or a run in moderate to heavy breezes. Under sail alone, the 36 MS is known for its "leisurely" pace; its low-aspect rig and significant wetted surface area mean it requires a stiff breeze to overcome its own inertia.

Handling is characterized by high initial stability but limited pointing ability. Owners frequently report that the vessel struggles to tack through the eye of the wind without the assistance of the engine, a common trait for boats with a 3-foot draft. However, the trade-off is a remarkably stable platform that does not heel excessively, making it an excellent choice for families or those prone to seasickness. The primary propulsion is often the reliable Perkins 4-108 diesel, which provides enough power to maintain 6 to 7 knots under power—essential since this vessel is often operated as a "trawler with a steadying sail."

Interior Comfort & Variations

The interior of the Gulfstar 36 MS is where the vessel truly shines, often drawing comparisons to condominiums of the same era. The "Twin Cabin" layout (as noted in original technical drawings) features a distinct separation of living spaces that was revolutionary for a 36-foot boat in 1970. The center cockpit design allows for a large aft cabin, which in some variants is accessed via a walkthrough and in others serves as a private suite with its own companionway.

The main salon is cavernous, thanks to the 12-foot beam, featuring a large galley and a convertible dinette. Early models utilized a heavy amount of Formica and faux-wood finishes, which Practical Sailor notes was a hallmark of Lazzara's "value-first" approach during the company's infancy. While the aesthetics may feel dated to modern sailors, the functional headroom and storage capacity remain superior to many modern 40-footers. The 36 MS was eventually refined into the 36 Auxiliary, which featured a deeper keel and a more traditional sailing hull, but the "MS" remains the definitive version for those seeking a floating home.

Known Issues & Buyer’s Checklist

Prospective buyers of a Gulfstar 36 MS should focus their inspections on the construction techniques of the early 1970s, which were occasionally experimental.

• Ballast Integrity: Early Gulfstars utilized iron slugs encapsulated in a concrete slurry within the keel. Over time, water can penetrate the fiberglass skin, causing the iron to rust and expand, which may lead to "keel smile" or structural cracking in the keel stump.
• Deck Delamination: The decks are typically balsa-cored. Like many yachts of this vintage, hardware that was not properly re-bedded can lead to core rot, particularly around the chainplates and stanchion bases.
• Fuel Tank Corrosion: The original fuel tanks were often made of black iron. In a marine environment, these tanks are prone to internal and external corrosion; replacement often requires significant cabinetry work or even engine removal.
• Chainplates: The original chainplate installations on early Gulfstars were sometimes criticized for being under-engineered for heavy offshore use. Any signs of weeping or rust streaks in the cabinetry near the shrouds should be treated as a priority repair.

Community & Resources

The Gulfstar legacy is maintained by a dedicated group of owners who value the brand's "built for comfort" ethos. Technical support and historical documentation are primarily handled through the Gulfstar Owners Association, which provides a repository for original manuals and refit guides. While the manufacturer no longer exists, the use of ubiquitous components like the Perkins engine and Lewmar hardware makes these vessels relatively easy to maintain through general marine suppliers.

The Verdict

The Gulfstar 36 MS is an unapologetic cruising platform that trades windward performance for unparalleled interior volume and shallow-water access. It is an ideal entry-level coastal cruiser for those who view the journey as a relaxation exercise rather than a technical challenge.

Pros:

• Exceptional Volume: Offers the interior space of a much larger vessel.
• Shoal Draft: The 3-foot draft allows for exploration of harbors inaccessible to most sailboats.
• Stability: A heavy, wide hull that provides a comfortable, upright motion in most sea states.
• Affordability: Generally offers one of the lowest "price-per-square-foot" entries into the cruising lifestyle.

Cons:

• Sailing Performance: Poor upwind capability and sluggish in light air.
• Build Quality Concerns: Early models require careful inspection of the iron/concrete ballast and deck cores.
• Aesthetics: The "houseboat" styling and heavy use of 1970s plastics may not appeal to traditionalists.
