Oyster 625 Sailboat Review, Specs, and Listings

Design and Construction

The 625’s composite structure is first-class, with a hull laminate of E-glass, Kevlar, and carbon fiber that is solid below the waterline and reinforced by a structural grid anchor. Above the waterline the topsides are foam-cored and vacuum-bagged, while the deck is balsa-cored with plywood worked into load-bearing areas. The exterior carries a cleaner, more modern bulwark profile than predecessors, a gentle sheer line bridging the stem overhang and reverse transom, and a tapered foredeck that flows into the sloping leading edge of the wraparound coachroof window. Integral fittings let a crew move easily from bow to stern, and the flush foredeck lines reinforce the modern look. Three keel configurations were offered: a standard 9-foot-2-inch high-performance bulb foil, a fixed shoal-draft option, and an optional centerboard arrangement.

Rig and Handling

The standard fractional sloop rig carries a traditional full-battened mainsail, though the test model wore the optional triple-spreader cutter rig with in-mast furling main and double headsails on husky electric roller furlers anchor. Under full sail in 12 knots of wind the boat held a steady 7.7 knots through the water and accelerated easily to nearly 9 knots on a beam reach when puffs arrived; swapping a staysail for the genoa lifted close-reach speeds to a comfortable 8.5 to 8.8 knots, and cracked off she topped 9.1 knots as wind entered the low teens. She tacked reliably through about 90 degrees and tracked beautifully, with a turning circle of just 1½ boatlengths. Under a 180-horsepower Volvo turning 2,000 rpm she cruised at 8 knots, and the tester measured sound levels of 60 dBA — the lowest he had recorded in over two decades of boat tests.

Accommodations

Below, the 625 offers spacious interiors for a sailing yacht under 20m, with well over 6 feet of headroom almost everywhere and a full-beam owner’s suite aft. The saloon houses Oyster’s signature triple Seascape windows with seven deck-saloon portlights and six more at eye level when seated, set against suede fabric and blond maple joinery. Buyers could choose several interior arrangements, including a fourth cabin accessed from the master that could serve as workshop, guest, or children’s space, and a forepeak layout for a full-time crew member reached by its own ladder and watertight door. The test boat slept seven in four cabins, though four berths were fairly narrow pilot-cabin bunks. A large cockpit separates social lounging from the working sailhandling area, with a smaller secondary cockpit aft holding dual helm stations and a centerline passage between them.

Known Issues

No structural or systemic defects affect the Oyster 625. The construction details that do appear — solid glass below the waterline, foam-cored vacuum-bagged topsides, balsa deck with plywood reinforcements — describe the build approach rather than any failure mode, and period reviews praised the execution without reservation.

Ownership and Refit Context

Oyster offered extensive customization to a buyer’s specifications, and the standard boat’s big forepeak locker, full-width lazarette, dual bronze sea chests with manifolds, 24-volt DC system with a large battery bank, second 150-amp engine alternator, and 11.5 kW genset speak to a platform built for long-range comfort. The 449-gallon fuel and 317-gallon water capacities, with 99 gallons of waste, support extended cruising. The 625’s displacement-length ratio of 182 and sail-area displacement ratio of 22.3 place her firmly in the performance-cruiser band for her size.

The Verdict

The Oyster 625 is a thoughtfully engineered 62-foot deck saloon that balances ocean-going substance with lively handling and a bright, customizable interior. She rewards the cruising family with quiet propulsion, easy sailhandling, and a layout that scales from owner-only to paid crew.
