Supersail 30 Information, Review, Specs

Sailing Performance & Handling

The Supersail 30 is characterized by a moderate displacement hull, a fin keel, and a spade rudder—a configuration that provides a balanced and responsive helm. Phil Curren, known for designing yachts that thrive in the heavy air of the Indian Ocean, ensured the Supersail 30 maintained a high degree of sea-kindliness even when pressed. Owners often report that the boat tracks well and remains predictable under a full press of sail, though it benefits from early reefing when winds exceed 18–20 knots to maintain a comfortable heel angle.

The rigging is typically a masthead sloop, which provides plenty of power for light-air performance, making it a competitive choice for twilight racing or club-level regattas. While it does not possess the pure planing speeds of modern ultra-light designs, its "racer-cruiser" pedigree ensures it is far more agile than the heavier full-keel cruisers of the same era.

Interior Comfort & Variations

Despite its 30-foot length, the Supersail 30 offers a surprisingly "large volume" interior, a hallmark of Curren’s design philosophy. The layout typically accommodates four to five people comfortably. Forward, a double V-berth provides the primary sleeping quarters, separated from the main salon by a private head. The salon usually features two opposing settees with a central table that can often be dropped to create additional berths.

The galley is positioned near the companionway for optimal ventilation and ease of access to the cockpit, usually equipped with a two-burner stove, a stainless steel sink, and top-loading icebox or refrigeration. High-quality timber joinery (often teak) was standard, giving the cabin a warm, traditional feel compared to the starker interiors of contemporary production boats. An aft quarter-berth on the port or starboard side provides additional sleeping space or acts as a convenient "sea berth" during passages.

Known Issues & Buyer’s Checklist

When inspecting a Supersail 30, particular attention should be paid to the following areas common to vessels of this vintage:

• Keel-to-Hull Joint: Like many racer-cruisers from the 1980s, the keel bolts and the surrounding fiberglass transition should be inspected for signs of weeping or "the smile" (cracking at the leading edge of the keel), which may indicate the need for re-torqueing or structural reinforcement.
• Deck Core Integrity: The decks are often a sandwich construction. Use a plastic hammer to "tap-test" around high-load areas like the stanchion bases, winches, and chainplates to check for delamination or soft spots caused by water ingress.
• Engine Service History: Many original units were fitted with Bukh or Sole diesel engines. These are reliable workhorses, but buyers should check the exhaust elbow for internal corrosion and the heat exchanger for mineral buildup, as replacements for older models can be expensive or difficult to source.
• Standing Rigging: If the rigging has not been replaced in the last 10 years, it should be factored into the purchase price as a mandatory safety upgrade, especially for those intending to use the boat for offshore coastal hops.

The Verdict

The Supersail 30 remains a highly regarded entry-level yacht for sailors who want a "do-it-all" boat on a budget. It offers a rare combination of offshore durability and a livable interior that feels larger than its dimensions suggest.

Pros:

• Excellent interior volume for a 30-foot boat.
• Solid offshore pedigree from a respected naval architect.
• Predictable and forgiving handling in heavy air.
• Classic aesthetics with high-quality interior woodwork.

Cons:

• Niche availability primarily restricted to the Australian market.
• Original engines and rigging likely nearing the end of their service life.
• Interior layout can feel cramped if carrying more than four adults.
