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.
