Leisure 27 SL Information, Review, Specs

The hull construction is robust, featuring heavy-duty hand-laid GRP that has contributed to the model's longevity. While the Leisure 27 was the primary production model, the 27 SL refined the deck layout to provide a more ergonomic cockpit and improved sightlines. On the same hull, the builder later explored the Leisure 29, which essentially utilized the 27’s proven underwater profile but added a "sugar scoop" transom to extend the waterline and provide easier water access.

Sailing Performance & Handling

The Leisure 27 SL is characterized by its predictable, "stiff" sailing characteristics. With a relatively high displacement for its length, it is not a light-air flyer but excels when the breeze freshens. Most units were delivered with a twin-keel (bilge keel) configuration, a design choice specifically requested by East Coast UK sailors who needed the ability to dry out in tidal estuaries. While the bilge keel variant sacrifices a few degrees of pointing ability compared to the rarer fin keel version, it provides a stable platform that resists heeling in gusts.

The boat’s handling is described by the Leisure Owners Association as balanced, though it requires a proactive approach to reefing to maintain optimal rudder authority. Because of its generous beam and high topsides, the 27 SL can experience significant windage when maneuvering in tight marinas. However, once under sail, the hull's momentum allows it to punch through coastal chops that would stall lighter 27-footers. The rig is a standard masthead sloop, and while it lacks the aggressive performance of contemporary cruiser-racers, it offers a secure, sea-kindly motion that reduces crew fatigue on longer passages.

Interior Comfort & Variations

The defining feature of the Leisure 27 SL is its interior volume, particularly its standing headroom, which reaches approximately 6 feet 1 inch—a rarity for a yacht of this vintage and size. The layout was designed for family cruising, typically offering five to six berths. This is achieved through a V-berth in the forepeak, a convertible dinette in the main saloon, and a sizeable quarter berth to starboard.

The SL variant often featured teak-faced marine plywood cabinetry and improved soft furnishings compared to the more utilitarian early models. The galley is functional for coastal hops, featuring a gimbaled stove and a compact sink, usually positioned to port. One of the most significant upgrades in the 27 SL was the refinement of the heads (bathroom) compartment, which is surprisingly spacious for a 27-foot boat, often including a hanging locker for wet weather gear. The integration of the engine—traditionally a Volvo Penta or Bukh diesel—is central, though the 27 SL’s engine box is well-insulated to minimize noise in the cabin.

Known Issues & Buyer’s Checklist

Prospective buyers should focus their inspections on several high-signal areas common to the Leisure range and GRP boats of this era:

• Osmosis: Like many British-built boats from the 1970s and 80s, the Leisure 27 SL can be prone to osmotic blistering. A moisture meter check of the hull, especially around the keel stubs, is essential.
• Keel Bolts and Gaskets: On bilge keel models, the joint where the keels meet the hull is a high-stress area. Inspect for "smile" cracks or signs of weeping, which may indicate that the keel bolts require tightening or the bedding compound has failed.
• Window Leaks: The large salon windows are a hallmark of the SL’s bright interior but are notorious for developing leaks over time as the original seals perish. Water ingress here often damages the interior wood veneers.
• Engine Service History: Many 27 SLs still carry their original Volvo Penta MD series engines. While reliable, spare parts for older units are becoming increasingly expensive, and buyers should check for exhaust elbow corrosion and heat exchanger efficiency.
• Deck Core: While the hull is solid GRP, certain deck areas may use a balsa or foam core for stiffness. Check for "spongy" sections around the mast step and stanchion bases, which indicate water penetration into the core.

Community & Resources

The primary hub for technical data and owner support is the Leisure Owners Association. This group maintains an extensive archive of original brochures, wiring diagrams, and specific "how-to" guides for the 27 SL. They are an essential resource for sourcing replacement parts that are no longer in commercial production, such as specific rudder bearings or window gaskets.

The Verdict

The Leisure 27 SL is a consummate "pocket cruiser" that prioritizes safety and habitable volume over raw speed. It remains a popular choice for families and couples seeking a robust vessel for coastal exploration without the high slip fees associated with 30+ foot boats.

Pros:

• Exceptional standing headroom and interior volume for its class.
• Sturdy construction capable of handling heavy weather.
• Bilge keel options allow for inexpensive drying moorings and tidal exploration.
• Strong owner association support and historical documentation.

Cons:

• Sluggish performance in light winds (less than 8-10 knots).
• High windage can make docking challenging in crosswinds.
• Aging original engines and GRP may require significant maintenance investment.
