The Spacesailer 24 stands as a quintessential example of the Australian "pocket cruiser" era, emerging from the prolific Swarbrick Bros Yachts yard in Western Australia during the 1970s. Designed by Kim Swarbrick, this 24-foot fiberglass sloop was conceived to bridge the gap between high-performance club racers and family-oriented weekenders. While the Swarbrick family is perhaps most famous for their involvement with the Sparkman & Stephens 34, the Spacesailer range—encompassing the 18, 20, 22, 24, and 27—became the backbone of recreational sailing in Western Australia and beyond. The 24, in particular, hit a "sweet spot" in the market, offering enough waterline length for coastal hops while remaining manageable for a shorthanded crew or a solo sailor.

Sailing Performance & Handling

On the water, the Spacesailer 24 is characterized by a surprising level of stiffness and a predictable, "big boat" feel that belies its modest dimensions. Unlike many lightweight trailer-sailers of the same era, the SS24 features a fixed fin keel (typically cast iron) and a substantial ballast ratio, which contributes to its reputation for sea-kindliness in the choppy conditions often found in the Swan River or Gage Roads. The hull profile utilizes a moderate beam and a relatively flat run aft, allowing the boat to track well on a reach while maintaining a balanced helm when pressed upwind.

The rig is traditionally a masthead sloop, though some variations exist depending on the specific production year. While it is not a dedicated light-air flyer, the boat performs admirably once the breeze exceeds 10 knots. Owners often report that the boat remains dry in a chop thanks to its flared bow sections. Handling is generally described as forgiving, making it a frequent choice for those graduating from dinghies to keelboats. Its displacement-to-length ratio suggests a hull built for durability and momentum rather than planing speeds, aligning with the Swarbrick philosophy of building robust, offshore-capable vessels.

Interior Comfort & Variations

The hallmark of the Spacesailer 24’s interior is its innovative use of space, specifically the "pop-top" roof—a common feature in Australian designs of this vintage. When at anchor, the central section of the cabin trunk can be raised, providing full standing headroom in the galley and saloon area, which is otherwise restricted in a vessel of this size. The layout typically accommodates five adults, featuring a V-berth forward, a convertible dinette, and a quarter berth to starboard.

The craftsmanship reflects the Swarbrick legacy of high-quality GRP (Glass Reinforced Plastic) construction. Interior moldings are usually finished with teak or mahogany trim, providing a warmth that many modern production boats lack. While the 24 is the most balanced of the small Spacesailers, it is often compared to its siblings: the Spacesailer 22, which offers a similar layout in a more compact frame, and the larger Spacesailer 27, which provides a fixed-headroom coachroof and a more dedicated offshore capability. The SS24 remains the most popular for those who prioritize the versatility of a boat that can be kept on a swing mooring or a high-and-dry facility.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Spacesailer 24 with a focus on structural longevity, given that most hulls are now several decades old. While the Swarbrick yard was known for thick laminates, there are specific areas that require scrutiny:

  • Keel Bolts and Joint: As with any fixed-keel yacht of this age, the keel-to-hull joint should be inspected for "smiles" or weeping. The internal keel bolts may require torque testing or replacement if corrosion is evident.
  • Pop-Top Mechanism: The struts and seals of the pop-top roof are a common failure point. Ensure the lifting mechanism operates smoothly and that the vinyl "curtain" (if equipped) is not rotted or leaking.
  • Deck Compression: Check the area around the mast step for any deflection or "crazing" in the gelcoat, which may indicate that the deck core (often balsa or plywood in certain sections) has softened or compressed over time.
  • Rudder Bearings: The transom-hung or spade rudders (depending on the specific sub-model) can develop play in the pintles or bearings, leading to a vibrating or "clunky" helm.
  • Chainplates: Inspect the stainless steel chainplates where they pass through the deck; leaks here can lead to moisture ingress in the interior bulkheads, compromising structural integrity.

Community & Resources

The model is supported by a dedicated following, primarily centered in Australia. The Spacesailer Association of Western Australia serves as the primary repository for technical data, rigging guides, and class racing rules. This association is one of the most active owner groups in the region, organizing regular championships and social events, which helps maintain the resale value and parts availability for the model.

The Verdict

The Spacesailer 24 remains a premier choice for the entry-level keelboat sailor who values Australian maritime heritage and robust construction. It balances the requirements of club racing with the practical needs of weekend cruising better than almost any other boat in the 24-foot category.

Pros:

  • Exceptional Headroom: The pop-top design provides comfort rarely found in 24-footers.
  • Sturdy Build: Hand-laid GRP construction from a renowned builder ensures long-term durability.
  • Active Class: A strong owners' association provides excellent social and technical support.
  • Balanced Handling: Forgiving enough for beginners while remaining rewarding for experienced sailors.

Cons:

  • Aged Systems: Original masts, wiring, and plumbing will likely require modernization.
  • Pop-Top Maintenance: The lifting roof introduces more potential for leaks compared to a fixed coachroof.
  • Iron Keel Care: Requires regular maintenance to prevent rust and maintain a fair hydrodynamic profile.
