Seafarer 31 Mk II Information, Review, Specs

Sailing Performance & Handling

The Seafarer 31 Mk II is defined by its McCurdy & Rhodes hull form, which utilizes a swept-back fin keel and a high-aspect spade rudder. This configuration provides the boat with a much tighter turning radius and more responsive handling than its predecessor, the Tripp-designed Mk I. With a displacement-to-length ratio that typically sits in the "moderate cruiser" range, the boat is known for a stable, predictable motion in a seaway. Owners often report that the boat tracks surprisingly well for a fin-keel design of its era, a testament to the balanced hull sections designed by McCurdy & Rhodes.

Under sail, the boat benefits from a masthead sloop rig that provides a healthy sail area-to-displacement ratio (approximately 15.1), allowing it to remain competitive in light-to-moderate breezes. While not a pure racing machine, the Mk II was marketed as a "racer-cruiser," and it remains a capable performer in PHRF club racing. Technical reviews from the period, such as those found in archival regional sailing publications, note that the boat stays remarkably dry in a chop due to its flared bow sections, though it can become tender if over-canvassed in winds exceeding 18 knots.

Interior Comfort & Variations

The interior of the Seafarer 31 Mk II was designed to maximize the living space of a 31-foot hull, offering a layout that was quite advanced for the early 1970s. The standard configuration features a classic V-berth forward, followed by a full-width head compartment. The main salon typically includes a pull-out settee to port and a fixed settee to starboard, providing sleeping accommodations for up to five or six adults when including the aft quarter berth.

A critical factor for prospective buyers is the "kit boat" history of Seafarer. Because many 31 Mk IIs were sold as "component yachts"—where the factory provided the hull and deck and the owner finished the interior—the quality of cabinetry and systems can vary wildly between individual hulls. Factory-finished boats usually feature high-quality teak joinery and a functional galley with a deep sink and icebox located near the companionway. The cabin offers approximately 6'2" of headroom, which was a significant selling point for a 31-footer at the time of its release.

Known Issues & Buyer’s Checklist

When inspecting a Seafarer 31 Mk II, the primary concern is the integrity of the balsa-cored deck. Like many boats of this era, the hardware was not always factory-sealed with epoxy, leading to moisture intrusion around stanchion bases, cleats, and the mast step. Spongy sections of the deck or brown staining around interior headliners are immediate red flags.

Another high-signal area for inspection is the chainplate attachment points. On the 31 Mk II, the chainplates are bolted to fiberglass-encapsulated wooden bulkheads. Over decades, leaks at the deck joint can cause these bulkheads to rot invisibly behind the fiberglass, compromising the rig’s structural integrity. Buyers should also scrutinize the rudder post and spade rudder assembly; being an early spade design, the internal skeleton of the rudder is prone to corrosion and "delamination swell" if water has penetrated the foam core. Lastly, because of the kit-built nature of many units, the electrical wiring and plumbing often lack the standardization found in mass-production boats like Catalinas or Pearsons, necessitating a thorough survey of the DC panel and through-hull fittings.

Community & Resources

Owners of these vessels often congregate around the Seafarer Yachts owner groups and technical forums. While the company is no longer in business, technical support is frequently found through the broader community of McCurdy & Rhodes enthusiasts. Detailed historical context regarding the builder’s evolution and the shift from Tripp to McCurdy designs is maintained through resources like the Seafarer Yacht Owners technical site, which provides archival data on various models.

The Verdict

The Seafarer 31 Mk II is an elegant, well-designed cruiser that offers a more spirited sailing experience than many of its heavy-displacement contemporaries. It is an ideal choice for a coastal cruiser who appreciates classic lines but wants the responsiveness of a modern underbody.

Pros:

• Excellent balance and tracking thanks to the McCurdy & Rhodes design.
• Graceful, timeless aesthetic that stands out in a modern marina.
• Spacious interior with standing headroom for taller sailors.
• Strong community support and historical pedigree.

Cons:

• High variability in interior finish quality due to "kit" versions.
• Common vintage issues like deck core rot and chainplate bulkhead decay.
• The spade rudder is more vulnerable to impact than the Mk I’s full keel.
