The South Coast 22 (SC22) stands as a quintessential example of the 1970s trailersailer movement, produced by South Coast Seacraft of Shreveport, Louisiana. Designed to bridge the gap between a nimble daysailer and a capable coastal pocket cruiser, the vessel became a staple of inland lakes and the Gulf Coast during its production run from the late 1960s through the early 1980s. Constructed with a robust fiberglass hull and a versatile swing keel, the SC22 was marketed as a familyfriendly boat that could be easily towed behind a standard American sedan of the era. Its enduring popularity stems from its balance of manageable dimensions and a surprisingly spacious interior, facilitated by a design that prioritized volume and stability over sheer racing speed.

Sailing Performance & Handling

Under sail, the South Coast 22 is characterized by a stable, predictable motion that favors the novice or the conservative cruiser. With a Displacement-to-Length ratio (D/L) hovering around 145 and a Sail Area-to-Displacement ratio (SA/D) of approximately 19, the boat is sufficiently powered for light-to-moderate air. It utilizes a masthead sloop rig that is relatively easy to tune and depower when the breeze freshens.

The defining feature of its handling is the 600-pound cast-iron swing keel. When fully extended to its 4' 9" depth, the boat tracks well and exhibits reasonable lift upwind, though it does not point as high as its deeper-keeled contemporaries like the South Coast 21 (an Alberg design). According to technical documentation maintained by the South Coast 22 Owners Association, the boat's 7' 7" beam provides significant initial stability, making it feel "stiff" in conditions where lighter dinghies would be struggling. However, like many swing-keel designs, the SC22 can become tender if the keel is not fully deployed or if the boat is over-canvased, necessitating early reefing of the mainsail once winds exceed 15 knots.

Interior Comfort & Variations

The interior of the South Coast 22 is widely regarded as one of the most efficient uses of space for a 22-foot hull. The cabin typically features a V-berth forward, followed by a small chemical head area, and a main salon with two settee berths. A notable innovation on many later models was the "pop-top" cabin roof, which, when raised, provides roughly 6' 2" of standing headroom in the galley and salon area—a luxury rarely found in boats of this size.

South Coast Seacraft offered several interior configurations, including a "Dinette" model and a "Standard" model. The Dinette version features a table that converts into a double berth on the port side, allowing the boat to theoretically sleep five adults, though four is the practical limit for comfort. The build quality reflects the era’s "overbuilt" philosophy, utilizing thick fiberglass laminates and simple, rugged wood trim. While the finishes are utilitarian compared to modern European cruisers, the layout's functionality for weekend trips remains highly regarded by the used-boat market.

The SC22 shares its DNA with other South Coast Seacraft siblings, most notably the South Coast 23, a larger, more traditional full-keel cruiser designed by Thomas Gillmer, and the South Coast 21, a slender, Alberg-designed racer-cruiser. While the SC21 was faster and more elegant, the SC22 surpassed it in sales due to the interior volume and the convenience of the swing-keel trailerability.

Known Issues & Buyer’s Checklist

Prospective buyers should focus their inspections on the mechanical and structural integrity of the swing keel and the deck core.

  • Swing Keel Assembly: The cast-iron keel is prone to oxidation if the epoxy coating is breached. More critically, the pivot bolt and the lifting cable (and its associated winch) are high-wear items. Buyers should inspect the "keel trunk" for cracks or signs of impact damage, as a failure here can lead to significant water ingress.
  • Deck Delamination: Like many boats of this vintage, the SC22 uses a balsa or plywood core in the deck. Soft spots are common around the mast step and the chainplates. If the mast step shows signs of sagging, it often indicates a compressed core or a failing compression post below deck.
  • Transom Integrity: Because the SC22 is frequently used with outboard engines, the transom should be checked for "spider" cracking or flexing, which suggests the wooden reinforcement inside the fiberglass laminate has succumbed to rot.
  • Pop-Top Gaskets: On models equipped with the pop-top, the vinyl or canvas "curtain" that seals the gap when the top is raised is often weathered or torn. While replaceable, it is a common source of leaks that can ruin interior cushions.

Community & Resources

The South Coast 22 benefits from a dedicated, albeit vintage, community of enthusiasts. The most prominent resource is the South Coast 22 Owners Association, which serves as a technical repository for original brochures, rigging diagrams, and maintenance logs. The association has historically been the primary conduit for owners looking to source specific parts or advice on keel trunk repairs.

The Verdict

The South Coast 22 remains a premier choice for budget-conscious sailors who require a trailerable boat with genuine overnight capabilities. While it lacks the refinement of modern designs, its "honest" construction and clever use of space make it a standout in the 22-foot class.

Pros:

  • Excellent interior volume for its length, especially with the pop-top raised.
  • Stable and forgiving handling characteristics ideal for beginners.
  • Easily trailerable, allowing for exploration of different sailing venues.

Cons:

  • Swing keel maintenance is mandatory and can be labor-intensive.
  • Performance is utilitarian rather than athletic.
  • Aged deck cores and original wiring often require significant restoration.
