The Seawolf 26 was drawn by British maritime architect David Feltham in the late 1970s and built by the British yard Seawolf Yachts Ltd. With fewer than 100 hulls completed, it remains a scarce small cruiser. Its proportions point to a modest, shoalminded coastal boat rather than a strippedout racer.

Design and Construction

The Seawolf 26 measures 26 feet 8 inches overall, with a beam of 9 feet 6 inches. Its length-to-beam ratio of 2.74 places it as roomier than 85 percent of similar designs.

The solid-fibreglass hull has bilge keels, a twin-keel arrangement that allows the boat to stand upright when beached. Draft is roughly 3 feet, depending on load, giving it access to shallow marinas that deeper fin-keel competitors can’t reach.

Displacement is 5,250 pounds, including 2,240 pounds of iron ballast. That gives a ballast ratio of 43 percent, higher than two-thirds of comparable sailboats. A displacement-to-length ratio of 272 places the Seawolf 26 among the “heavy cruisers” in its size range, with only about a third of similar boats weighing more.

Rig and Performance

The Seawolf 26 carries a fractional sloop rig with a stated sail area of 315 square feet. Its sail-area-to-displacement ratio is 16.68, a modest figure that favors control over outright acceleration. The wetted surface of the hull is about 193 square feet.

Recorded figures give a calculated maximum speed of nearly 3.9 knots and a theoretical displacement hull speed of about 6.1 knots. The immersion rate is roughly 680 pounds per inch.

The Motion Comfort Ratio is 18.1, said to be more comfortable than 42 percent of similar designs. Its capsize screening value of 2.19 would exclude the boat from ocean racing under the same source’s standard. That points clearly toward coastal cruising rather than bluewater ambitions.

Accommodation and Systems

Fresh-water capacity is 20 US gallons, while the fuel tank holds 10 US gallons. The boat may be fitted with an inboard Volvo Penta 2001 diesel rated at 7 hp.

Those capacities are better suited to weekend gunkholing and short hops than extended liveaboard cruising. Meanwhile, the shallow-draft, twin-keel platform opens up more anchorages and drying harbors to the cruiser.

Limitations

The Seawolf 26’s main constraints follow directly from its intended role. Its capsize screening value and heavy-cruiser displacement-to-length ratio describe a boat that trades offshore certification and light-air sparkle for stability and beachability.

The shallow draft and twin-keel arrangement also limit upwind bite compared with an equivalent fin-keel boat. The modest engine output is suited to auxiliary use rather than sustained motoring.

The Verdict

The Seawolf 26 is a deliberate small cruiser: beamy, heavily ballasted for its length, and freed from draft worries by its twin-keel hull. Feltham and Seawolf Yachts Ltd. created it for sheltered-water exploration and drying moorings, not ocean circuits. Its scarcity makes any example a find for the shoal-water purist.

Pros

  • Twin bilge keels allow beaching and access to shoal water
  • Ballast ratio is higher than that of two-thirds of similar designs
  • Beamy layout ranks as roomier than 85 percent of comparable boats

Cons

  • Capsize screening value excludes it from ocean-race acceptance
  • Modest 7 hp auxiliary engine and 10 US gallon fuel capacity
  • Fewer than 100 built, limiting familiarity within the spares network
