The Catalina 310 occupies a particular niche in American production sailing: a genuine twoperson coastal cruiser designed without the compromises that come from trying to be all things to all buyers. Built from 1999 to 2011 under the direction of Gerry Douglas, Catalina's vice president and chief designer, the 310 grew directly from the lineage of the 320, inheriting a fine forward entry, flat aft section, and narrow waterline beam — a hull form Douglas refined to carry load without altering trim. At 31 feet on deck and displacing over five tons, it is the heaviest of its competitive cohort, a decision that shapes nearly everything about how the boat sails, lives aboard, and ages.

Hull Form and Design Philosophy

Where contemporaries in the 31-to-32-foot class chased lighter displacements and higher sail-area-to-displacement ratios, the 310 pursued a different brief entirely. Douglas describes the goal as "a small boat with big-boat feeling," specifically invoking the character of the larger Catalina 38. The hull carries rounded sections amidships to provide weight for load-carrying without changing trim as stores are added — a practical concession to coastal cruising realities. Visually, the 310 is the most traditional-looking of its peers, with a moderate bow overhang, high-aspect mainsail, and rounded stern — proportions that read as composed rather than fashionable. The fin keel carries a lead bulb, and the spade rudder provides direct feedback. Construction follows Catalina's established recipe: solid fiberglass hull with double thickness on the centerline, plywood-cored deck, and end-grain balsa in the cabintop — with aluminum backing plates laminated into the layup so deck hardware threads into tapped holes rather than requiring through-bolts, which reduces leak pathways and simplifies future removal.

Rig and Sail Handling

The 310 carries a double-spreader masthead sloop rig with shrouds terminating on the cabintop, leaving decks 16 to 18 inches wide with handrails so crew can move forward unimpeded when heeled. The standard headsail is a 135-percent genoa, with a 155-percent option for those wanting more light-air drive. Mainsail controls are positioned forward of the companionway, keeping hardware out of the cockpit social space, and the boat is equipped with a solid vang as standard, which improves sail shape across a range of points of sail. Catalina also fitted four Lewmar winches as standard equipment — a meaningful differentiator against competitors that treated primary winches as paid options. The helm is described as well-balanced, and the boat tacks within 80 to 90 degrees under typical conditions. Practical Sailor's test crew found that despite the heavier displacement, the 310 performed well in light air and showed no meaningful disadvantage relative to lighter rivals, while promising a drier and more comfortable motion in a blow or steep chop — a consequence of its greater mass and more conservative hull form.

Cockpit and Deck Ergonomics

The cockpit is wide: 43 inches between seats, which owners consistently note is too broad without a footrest to brace against when heeled. The original boats included a teak strip on the sole for this purpose, but it was removed after early owners complained it was a toe-stubber — a design decision that subsequent owners have tended to reverse by adding their own strip. Seat length runs 78 to 80 inches, long enough for a six-footer to stretch out. The steering pedestal houses instruments and a folding cockpit table. One of the 310's cockpit compromises is storage: a hatch under one seat serves as an emergency exit for the aft compartment, reducing the available locker volume compared to a boat without that throughway. The wheel is a 32-inch stainless unit, adequate for steering from the helm seat but too small to drive effectively from the rail. Cable steering is fitted — more conventional than the rack-and-pinion on Hunter's competing 326 and perceptibly less crisp, though well within the expectations of the intended buyer.

Accommodations

The 310's interior layout embodies a deliberate and clearly stated design philosophy: a "drink eight, feed four, sleep two" boat optimized for a couple rather than a crowd. The standout feature is the forward stateroom, which offers a queen-sized island berth with 24 inches of clearance on both sides — two people can get in and out without disturbing each other, which Douglas cites as a major selling point and which genuinely distinguishes the 310 from competitors that squeeze a V-berth into the bow. The aft sleeping area is wide open and enclosed by a curtain rather than a door, an explicit trade-off to preserve saloon length and air flow; it accommodates children or a single adult comfortably. The saloon runs wider amidships than competing layouts, with 12 to 14 additional inches between the settee backs compared to the Hunter 326, creating more lounging space — but neither the settee to starboard nor the dining area is intended as a sleeping berth. The pedestal table arrangement uses a 16-by-22-inch cocktail table that converts to a dining surface by placing a portable tabletop on it; the 30-pound top stores in the aft compartment, and owners reliably describe it as cumbersome. The head earns specific praise: larger than competitors, with a curtain-separated shower and deep medicine cabinet with under-sink storage. The galley provides meaningful counter space, and the Universal M25XP diesel — a 26-horsepower unit — drives the boat at five to six knots under power with acceptable noise levels below.

Known Limitations

The 310's weight relative to its sail area is the clearest performance trade-off. Its sail-area-to-displacement ratio of 16.72 is conservative against lighter competitors, and performance suffers particularly when sailing below a broad reach when the headsail is blanketed by the main. The boat will not appeal to anyone prioritizing speed, and it will be noticeably slower downwind than a lighter rival of similar length. The cockpit footrest issue is minor but persistent — virtually every owner eventually addresses it. The cumbersome dining table is a recurring complaint, noted consistently by owners as one of the only meaningful disadvantages of an otherwise thoughtful layout. The convertible table works, but it demands cabinet space in the aft compartment and physical effort every meal. Prospective buyers should also note that the shoal-draft configuration will develop more leeway and lose some lift compared to the deep-draft fin — a real consideration for anyone planning to sail in areas with strong currents or frequent close-hauled passages.

The Verdict

The Catalina 310 is a well-resolved coastal cruiser for sailors who know what they want: a comfortable, confidence-inspiring boat for two people to live aboard for extended periods without the boat fighting them. It is heavier and slower than its nearest competitors, and it wears that trade-off honestly rather than hiding it. Gerry Douglas's stated intent — a couple's boat, not a rendezvous host — is legible in every layout decision, and buyers who share that priority will find the 310 delivers on it consistently. What Practical Sailor's editors concluded after sailing all three competitive candidates still stands: they'd go with the Catalina for the hull form, the familiar sailing characteristics, and the open floorplan's air and traffic flow. For the intended mission, those judgments hold.

Pros

  • Island queen berth in the bow with walk-around clearance on both sides
  • Four Lewmar winches standard; competitors charge extra for primaries
  • Heavy displacement means drier, more comfortable motion in a chop
  • Fine forward entry and flat aft sections carry loads without trim change
  • Solid-glass hull with aluminum backing plates reduces leak pathways
  • Oversized head with separated shower stall

Cons

  • Conservative sail-area-to-displacement ratio means slow downwind performance
  • Cockpit too wide without a footrest; owners must add one themselves
  • Convertible dining table is heavy and cumbersome to deploy
  • Cable steering less responsive than rack-and-pinion alternatives
  • Aft sleeping area enclosed only by curtain, not a proper door
  • Shoal-draft option meaningfully compromises upwind performance
