The Allied Seawind Mk II Cutter traces its lineage directly to the original Allied Seawind, a 30foot ketch that earned its place in history as the first fiberglass sailboat to circumnavigate. Thomas Gillmer, who drew the original Seawind in 1960, returned to design the Mk II in 1975 as a larger, heavier successor; the result is a 31'7" cutter (though the great majority of the 130 hulls built were ketches, with only 11 cutters and five sloops produced) that Allied built on the Hudson River until the yard closed at the end of 1981. The Mk II is a foot longer, a foot wider, and carries an extra foot of waterline over the original, gains that added 2,700 pounds to a 14,900pound displacement and reshaped the boat into a more substantial cruiser without abandoning Gillmer's conservative seakeeping philosophy.

Allied Seawind Mk II Cutter Buyer's Guide

The Allied Seawind Mk II Cutter occupies a narrow niche in the used market: of roughly 120 to 130 Mk II hulls built between 1975 and Allied's closure at the end of 1981, only 11 left the factory as cutters, the rest being ketches with a handful of sloops. Thomas Gillmer's 31'7" design carries a 14,900-pound displacement on a 25'6" waterline, a 10'5" beam, and 4'6" draft over a long keel with 5,800 pounds of internal lead. A shopper chasing a cutter-rigged example is therefore hunting a scarce variant of an already limited production run, and the boat's details reward a careful, evidence-based inspection rather than a glance at cosmetics.

Layouts on the Used Market

Most boats you will meet are the standard masthead ketch; the cutter simply moved that same mast aft about a foot and lengthened the mainsail foot, trading a slightly smaller total sail area for a single-headstay working rig. Below decks the arrangement is consistent across rigs: a V-berth forward with hanging locker and wash basin, a compact head with only toilet and shower, asymmetrical port and starboard settees in the main cabin, a drop-down table from the forward bulkhead, and an aft galley with deep sink. The one layout shortfall cited in period review is the absence of any navigation station, so a buyer who wants a dedicated chart desk will need to adapt the quarter berth or settee space. Later hulls (those built after the yard's 1979 interior update) show the best-finished cabins of the Allied line.

Equipment and Common Upgrades

Consequence-driven equipment on these boats clusters around power, deck hardware, and sail handling. The standard four-cylinder Westerbeke 27 diesel (some early spec sheets name a Vire) lives under the cockpit sole and was original fit; an optional anchor windlass sat neatly between the two 12-inch foredeck cleats, and an Edson rack-and-pinion wheel was standard steering. For energy and ground tackle, a buyer should verify windlass presence and the condition of the welded aluminum bilge fuel tank, which some owners note lacks an inspection port. Sail handling centers on the cutter's twin headstays allowing twin downwind jibs and a bridgedeck traveler; Hood working sails were original. Comfort items include a freshwater cockpit shower recessed in the footwell and an icebox with four inches of foam — worthwhile but secondary to structural and rig checks.

What to Inspect

The bowsprit is a massive teak platform, and its double bow rollers sit so far outboard that the anchor rode chafes the pulpit stanchion when the rollers are used — examine the stanchion base and rode for wear. The fuel tank in the bilge has no inspection port per some owner reports, so confirm tank condition indirectly through fill and vent lines. Engine access was rated only fair by testers: the Westerbeke is crammed beneath the cockpit sole, demanding that the ladder and aft panel be pulled to reach the dipstick, though an oil pan keeps spills out of the bilge sump. Also check that neither the shower nor the icebox drains into the deep bilge, a factory feature worth preserving.

Availability and Buyer's Takeaway

The cutter variant is a rare find among used Allied Seawind Mk II boats. For the cutter specifically, the short checklist is: confirm cutter rig (mast shifted aft, longer mainsail foot); inspect bowsprit roller chafe; verify fuel tank and engine access reality; check for absent nav station and plan a workaround; and prefer a post-1979 hull for interior finish. The Mk II Cutter is a rare, sturdily built Gillmer cruiser whose quirks are manageable with eyes open.
