Marshall 22 Cat Sailboat Review, Specs, and Listings

Design and Construction

The Marshall 22 is an honest translation of the classic Cape Cod catboat proportions into fiberglass. At just over 22 feet on deck and 21 feet, 4 inches at the waterline, the hull carries a 10-foot, 2-inch beam — nearly half the waterline length, consistent with the catboat rule of thumb. The vertical transom sports the traditional barn door rudder, the mast rises from the very bow, and a generous centerboard trunk bisects the cabin. With the board up, draft is a mere two feet, opening a world of shallow anchorages and tidal creeks inaccessible to fin-keel sloops.

Hull construction follows the schedule Breck Marshall developed himself: hand-laid mat and roving bonded with polyester resin, with seven basic plies augmented by additional laminate in the forepeak, garboard, and centerboard trunk. The mast step alone comprises 25 plies, laminated in its own mold. The hull-to-deck joint uses no mechanical fasteners; instead, four successively wider bonding strips create a thick fillet and a leak-free monocoque unit. No interior liner is fitted, which simplifies maintenance and inspection. In 2009, closed-cell foam replaced plywood in the transom, rudder, main cabin bulkhead, and floor frames, addressing the only chronic structural vulnerability in older boats.

The most significant production change came in 1983, when a molded fiberglass cockpit replaced the original plywood-over-fiberglass construction. This improved durability, drainage, and ease of cleaning, and added three lazarettes plus a port-side icebox. Buyers evaluating pre-1983 boats should be aware that the original plywood iceboxes almost universally develop rot and air leaks.

Rig and Handling

The gaff rig of the Marshall 22 demands a different relationship with wind than a marconi sloop — and rewards sailors who learn its rhythms. The 29-foot aluminum mast is tapered and foam-filled in its lower six feet for stiffness; the only standing rigging is the traditional forestay. A stainless-steel, vinyl-lined gaff saddle replaces the traditional wooden jaws and is durable in service, but bent hardware requires prompt replacement before it compromises the gaff's function.

The 388-square-foot mainsail is the boat's single control surface, and managing it well is the skill that defines catboat sailing. Keeping the mast raked forward and peaking the gaff as high as possible are both essential to upwind performance. A single reef is called for at around a steady 15 knots, and the boat handles 25- to 35-knot gusts competently when double-reefed. In a 12-knot breeze the hull moves at around 5.5 knots; in 15 to 18 knots it can reach 6.5 knots or better, and owners who have removed the engine entirely report regular 6- to 7.5-knot passages.

Tacking through 50 to 60 degrees is typical, depending on conditions, and owners consistently report reliable stays. Very light air — below five knots — is the rig's weakest suit, where the boat's displacement and prop drag take a toll. A three-blade propeller is standard; it provides better maneuvering and punches through chop more effectively than a two-blade, at the cost of slightly more drag under sail.

Accommodations

The cabin of the Marshall 22 packs more usable space than its 22-foot LOA would suggest, thanks to the generous beam. The layout has evolved over the decades, but the fundamentals are consistent: a pull-out double berth to starboard, a galley counter with sink to port, and two narrow forward berths flanking the head. From the late 1960s onward, the head was repositioned behind a partial bulkhead and curtain, affording some level of privacy while preserving a reasonably open feel in the main cabin.

Standing headroom is not available — the deliberately low topsides reduce windage and keep the hull proportions true to the catboat tradition. Seated headroom accommodates those up to about five feet eleven inches. Ventilation is the interior's main weakness; many boats have a non-hinged forward hatch requiring a makeshift prop, and even with an opening port at the forward cabin face, a solar ventilation fan is widely recommended to control moisture. Optional cedar staving in the cabin and cockpit, along with teak trim around the coamings, appears on many boats and significantly improves the interior feel.

The cockpit is the great social space of the Marshall 22 — large, uncluttered, and more comfortable than those of many bigger boats. The optional dodger, onto which a cockpit awning zips, is considered essential by most owners for genuine cruising use.

Known Issues and Inspection Points

The Marshall 22's fiberglass hull is regarded as essentially bulletproof by experienced owners, and hull blisters have rarely been a problem. The areas that warrant close attention at survey are more specific and predictable. Older boats equipped with the plywood-over-fiberglass transom and rudder cores should be probed for moisture intrusion, typically caused by damaged or improperly bedded fittings. If core damage exists, repair is generally considered worthwhile given the boat's structural solidity and market standing.

The extruded aluminum mast on older examples should be examined for corrosion caused by the stainless steel screws attaching the gooseneck — this reaction can be insidious and occasionally a new mast is the safest approach. The centerboard pennant should be checked for chafe; the bronze pivot pin, buried in the hull laminate, is rarely a problem in the absence of severe damage. The cockpit-to-cabin joint is a known entry point for rainwater that collects beneath the companionway steps; a renewed caulk bead helps, though the dodger provides a more complete solution.

Engine history matters. Early boats came with Palmer, Atomic 4, or Gray Marine gasoline engines; Yanmar's 3GM20 diesel became standard in 1980 and is widely considered a generational improvement in reliability. The 2GM20 followed in 1985; when that model was discontinued around 2005, the 3YM20 freshwater-cooled unit took over. Boats fitted with a replacement engine should be carefully surveyed to confirm professional installation and unobstructed fuel-line routing. The 12-gallon aluminum fuel tank under the starboard seat should be checked for leaks; access for replacement is reasonable but not trivial.

Refits and Upgrades

The Marshall 22 repays thoughtful investment. The most common refit priorities reported by owners align with the boat's known weaknesses: a new mainsail, a compliant marine head with holding tank, a dodger, and updated electronics. The gaff rig is demanding on sailcloth, so prospective buyers should inspect the mainsail carefully during sea trial — a kink at the inboard batten-pocket ends signals stretched fabric that re-cutting will not fully cure. Experienced owners recommend obtaining detailed written quotes from at least two sailmakers familiar with gaff rigs, and ensuring the boat carries at minimum two rows of reef nettles.

For those upgrading from the original plywood cockpit to take advantage of the 1983-onward molded version, Marshall Marine has historically served as both parts supplier and technical resource — a notable advantage of buying a boat still supported by its original builder. Brightwork restoration, running rigging replacement, and basic electrical work are realistic DIY projects given the straightforward, liner-free interior and accessible engine space.

The Verdict

The Marshall 22 Cat occupies a singular position among American production sailboats: a genuine working catboat adapted for fiberglass production, still built by the founding family, with a living community of owners and an active builder relationship. It is not a boat for everyone. It asks for a particular set of skills — reefing discipline, comfort with weather helm management, and willingness to adopt what one reviewer calls the catboat crouch going below. Its beamy hull and powerful gaff rig are at their best in the sheltered sounds and tidal estuaries of the Northeast rather than exposed offshore passages, though some boats have made ambitious coastal passages.

For sailors who embrace those terms, the rewards are considerable: unmatched shallow-water access, a genuinely stable and stiff hull, a cockpit that accommodates a crowd, and a boat that has demonstrated the ability to outlast its owners with proper servicing.
