The Mariner 28 is a solid, fullkeel coastal cruiser designed by Peter D. Canning and built by Mariner Yachts in East Greenwich, Rhode Island. Roughly 150 to 200 hulls were produced between 1977 and 1983. With heavydisplacement fiberglass construction and a traditional layout, she was intended for extended coastal cruising, weekend getaways, and light offshore passages rather than racing.

Design and Construction

At 28 feet overall, with a 23-foot waterline, 9.5-foot beam, 9,000-pound displacement, and 3,500 pounds of ballast, the Mariner 28 is built to track and absorb rather than sprint. Her heavy-displacement fiberglass construction and long, encapsulated keel define her seagoing character.

The long encapsulated keel provides excellent directional stability and grounding forgiveness, a practical advantage for coastal sailors who might touch bottom in an unfamiliar anchorage. Mariner Yachts built her as a straightforward, durable cruiser with no pretense toward the racecourse.

Rig, Performance, and Handling

The Mariner 28 has a masthead sloop rig, with a standard I measurement of 36 feet and J of 11.87 feet. The mainsail is about 151 square feet, while the 115-percent jib is close to 207 square feet. Owners could also fly genoas up to roughly 150 percent and a 555-square-foot asymmetrical spinnaker.

The masthead sloop rig provides balanced handling and good performance in moderate-to-strong winds. Paired with the keel’s directional steadiness, the sail plan contributes to a boat well regarded for seaworthy motion, a dry ride, and durability across varied coastal conditions. Performance is moderate in very light air, however, and the Mariner 28 is clearly not a light racer.

Accommodations

Below, the Mariner 28 has a comfortable, traditional interior with four to six berths and around 6 feet of headroom. The layout includes a forward V-berth, settee berths in the saloon, a working galley, and a private, enclosed head.

It’s a classic cruising arrangement: a bow berth for sleeping, settees for lounging or additional berths, and dedicated spaces for cooking and the head. The layout suits weekends and longer coastal hops, where a proper galley and enclosed head matter more than saving weight for racing.

Verdict

The Mariner 28 is a purposeful small cruiser for sailors who value steadiness, a dry ride, and a traditional layout more than speed. She offers a forgiving keel and a balanced rig in a breeze, though she asks for patience in calm conditions. With a known production run and a simple, robust formula, she remains a sensible entry into extended cruising.
