O'Day 37 Buyer's Guide
Shopping the brokerage market for an O'Day 37 means looking at a 1978–1984 center-cockpit sloop that earned its reputation with charter fleets and families who wanted separated sleeping quarters without stepping up to a 40-footer. C. Raymond Hunt Associates drew the design for O'Day Corp., and the boats you meet today are almost all the same general spec: 37 feet overall, a deck-stepped single-spreader rig, and a Universal diesel down below. The appeal is a real aft cabin with its own head, a rare trick in this length band, but the used fleet also carries a known set of weak points an inspector should chase before money changes hands.
Layouts on the Used Market
The interior plan centers on a small port galley with double sinks and a two-burner alcohol stove, a drop-leaf table between opposing settees in the main saloon, and a forward V-berth behind folding doors. The headline feature is the aft cabin with an athwartships double and a private shower head, reached past a wheel pedestal that crowds the threshold. Headroom runs about 6 feet 4 inches in the main cabin. Teak joinery is simple and well done, and most boats retain the original three-cabin, two-head arrangement with ample drawers throughout.
Equipment and Common Upgrades
Boats commonly come with a bimini, dodger, radar, spinnaker, and chartplotter as fitted equipment, which together mean a buyer gets weather protection, offshore visibility, and modern navigation without immediate outlay. Less commonly, you will find solar panels, a wind generator, dinghy davits, or autopilot as owner upgrades — these matter more for liveaboard or passagemaking plans since they speak to independent power and hands-off steering. Canvas and sail-handling gear are the practical clusters: a dodger and bimini keep the deep cockpit usable, while a spinnaker adds light-air range the sloop otherwise lacks.
What to Inspect
Most owners cite the original hatches and especially the plastic portlights needing upgrading and often full replacement. The flush forward hatch is prone to leaking, and on some boats the forward deck prisms or skylights leaked as well. The original standing rigging used swaged terminals, and if those have not been renewed they must be. Chainplates sit in the middle of the narrow side decks and are hard to reach from below, so inspect for hidden corrosion. The cast single anchor bow roller is a bit undersized, and engine access behind both companionways is poor, with the stuffing box particularly difficult to reach — one owner fitted a dripless unit to resolve it.
Availability and Buyer's Takeaway
These boats turn up in the United States, the Netherlands, and Greece. For a buyer, the short checklist is: confirm hatches and ports have been renewed or budget for it; verify rigging terminals are modern; inspect chainplate areas despite poor access; check the forward hatch and any forward skylight for stain; and assess engine and stuffing-box access realistically. A sound example rewards you with a genuine small center-cockpit cruiser that tracks well and sails steadily once the wind fills.
