Design and Construction
The hull is solid fiberglass with a fin configuration and a rudder carried on a skeg, a combination that gives directional control separated from the keel while keeping the profile clean. The 308 displacement-to-length ratio describes a boat of moderate heft for her length rather than a featherweight racer, and the 31.28 comfort ratio reinforces that this is a vessel meant to carry crew and stores without thrashing. Her capsize screening figure of 1.80 sits where one expects a bluewater-capable cruiser rather than a coastal weekender, and the derived hull speed from that waterline suggests she will hold her own on a passage once the breeze fills. Ericson Yachts built her in the early 1970s, and the 37's construction predates the Tri-axial Force Grid system that the builder would later introduce on the Ron Holland designs — she is a conventional solid-glass King hull, not a grid-structured later-generation Ericson.
Rig and Handling
As a masthead sloop the Ericson 37 carries a reported sail area of 613 square feet, split between a 247-square-foot mainsail and a 366-square-foot foretriangle, with an I of 48 feet and a J of just under 42 feet. The resulting sail-area-to-displacement ratio of 15.50 is moderate — enough to drive the 16,000-pound hull with reasonable purpose in a breeze, without demanding a large crew to manage the canvas. A 12.8-meter mast height keeps the center of effort within reason for a boat of this displacement, and the skeg-rudder arrangement typically lends a measure of helm steadiness when the boat is pressed. With 11.33 feet of beam and a 5.75-foot draft, she balances interior volume against the ability to work into shallower anchorages than a deeper fin would allow.
Accommodations
Below, the Ericson 37 provides six feet three inches of headroom, a figure that speaks to a cabin trunk proportioned for standing comfort rather than a low-slung racing interior. The 11.33-foot beam translates to a saloon and quarter layout with usable width amidships, and the 28.5-foot waterline gives the accommodation a reasonable fore-and-aft footprint for a 37-footer of the period. The layout follows the conventional masthead-sloop arrangement of the mid-1970s, with the volume distributed across the length of the hull rather than concentrated in a single great cabin.
Power and Systems
Auxiliary propulsion is a single 30-horsepower Universal Atomic 4 gasoline engine, the standard period powerplant for a boat of this class and era. The gasoline fuel arrangement is worth noting for any modern buyer, as it carries different storage and ventilation expectations than a diesel setup.
The Verdict
The Ericson 37 is a short-production King-designed cruiser that pairs a stable 50-percent ballast ratio and moderate displacement with a practical masthead rig and a headroom-friendly interior. She is a product of a defined two-year window and a specific design hand, which makes her a reasonably identifiable target for the buyer who values a known pedigree over a long-running model line.
Pros
- Lead-ballasted fin hull with skeg rudder and a 50 percent ballast ratio for stability
- 6-foot-3 headroom and 11.3-foot beam give a roomy, standing-comfortable interior
- Moderate 15.5 sail-area-to-displacement ratio suits a small crew
Cons
- Gasoline Atomic 4 auxiliary rather than diesel
- Brief 1973–1975 production limits fleet size and later-era upgrades
