Hull Form and Construction
The 310's hull is rounded and relatively narrow with lots of freeboard and beam on deck, and the sheer runs table-straight — a silhouette that reads as modern efficiency rather than classic grace. Underwater, the hull is solid glass up to the waterline, above which a Baltek balsa core runs to the sheerline. A molded fiberglass reinforcing grid is glassed into the hull, with extra fabric wrapping the grid to spread rig and keel loads into the laminate — an approach descended from Lars Bergstrom's structural work on the racing yacht Imp in 1974. The deck is cored with a combination of balsa and plywood, and the hull-to-deck joint is sealed with 3M 5200 and through-bolted on six-inch centers, producing a strong chemical/mechanical bond that creates no through-hull holes in the topsides. The molded interior liner is polyester-puttied and fiberglass-taped to the hull, with all liner-to-hull contact points bonded; Hunter describes the arrangement as overkill for structural redundancy. The composite rudder and rudderstock construction drew particular praise during a factory inspection, as did the engineering around mast placement, window bedding, and anchor well assembly — few owners had even a small beef with Hunter's basic construction.
The B&R Rig and Sailing Performance
The 310's fractional sloop rig is the single most distinctive feature and the most debated. Developed by the late Lars Bergstrom, the B&R rig combines cross-stressed diagonals, cap shrouds, and intermediates with swept-back spreaders and a conventional headstay, eliminating backstays entirely. Deck-mounted struts above the gooseneck help make masts lighter, thinner, and cleaner, reducing pitching and heeling tendencies. The arrangement permits a big-roach mainsail with full-length battens where area can be added while keeping the center of effort low, and lazy jacks tame the doused sail with minimal fuss. In a crisis scenario, racing skipper Steve Pettengill broke a shroud mid-race and noted that no other rig would have stayed in the boat — and the jury-rigged B&R carried the boat through two capsizes and three gales to the finish.
The trade-off is practical: swept-back spreaders tend to poke alarmingly into the mainsail when sailing downwind, which limits comfort running dead downwind. The 310 is also not well-suited to the apparent-wind sailing that makes that restriction less painful on faster, lighter designs. The sail area — roughly 463 square feet in standard configuration — may balance design displacement on the drawing board, but on the water a small sail plan gets overwhelmed by actual displacement. The boat accelerates slowly and, in the words of the Practical Sailor review, does not ghost well. Owners are regularly advised to reef early, though testers found the hull reasonably stiff in light going — a reflection of the ballast/displacement ratio of roughly 38 percent. The shoal-draft bulb-wing keel option trades some efficiency for versatility but produces significant parasitic drag that is noticeable in light to moderate air, especially upwind. The standard deep keel is the more capable performer. The 310 holds a PHRF racing average handicap of 168, which places her solidly in the cruising category rather than the performance bracket.
Cockpit and Deck
Above decks, the 310 is genuinely well thought out. The virtually circular cockpit well, achieved by taking the seatbacks right out to the sheer, creates an unusually spacious and secure helm environment. A molded table and steering pedestal sit at the cockpit center. The standard radar arch clears the mainsheet out of the cockpit, provides a mounting point for traveler controls, and makes a bimini practical — one owner described it as beating the heck out of sawing holes in the house for mounting instruments. The helm seat pivots to become a gate to the walk-aboard transom, and the swim platform shower control assembly is convenient but unobtrusive. Deck hardware is intelligently sited — non-skid is serious, struts serve as handholds, and a windlass lives in the anchor locker. The rack and pinion steering, rather than conventional cable-and-quadrant, draws consistent praise from owners for its mechanical precision. The one structural note worth flagging: the chainplates bolt horizontally through the deck bulwark, freeing the interior of tie-rod clutter, but creating through-deck holes that could admit leaks and placing some stress on the hull-to-deck joint under shroud tension.
Accommodations
Privacy is the central theme below. Double berths forward and aft are separated by as much boat as possible, each enclosed by solid doors — an unusual and genuinely appreciated arrangement in a thirty-foot boat. The saloon sits farther forward than conventional layouts, opening up the midships area and contributing to the feeling of separation between staterooms. Interior light is exceptional, thanks to windows and hull ports in astounding profusion. Overhead, a molded headliner provides an attractive finish and some thermal and acoustic insulation. Locker fronts use positive push-button closures, reading lights are well-placed and abundant, and dishware stowage is described as useful and space-efficient. One owner summarized life aboard for a small crew and a dog as just about perfect. The aft cabin athwartships berth drew one owner complaint about height — too low to be comfortable or convenient — and cross-ventilation in that cabin is minimal. There is room beneath the saloon settees but not behind them, and the bilge is shallow. The freestanding engine box occupies the middle of the living and sleeping area, and living with its considerable noise and vibration in the living room/kitchen is the practical cost of the otherwise excellent engine access.
Known Issues and Niggling Problems
Early-production examples generated a cluster of owner complaints worth knowing. Water heaters arrived cracked, hardware was missing at delivery, and one owner found none of the gauges — waste, water, or fuel — worked at all. The mast leaked at the plate gasket on multiple boats. Shift and throttle cables have come unlinked or broken. Head leaks appeared within the first season on some boats. Bilge pump hoses arrived cracked. Under power, some boats do not track well and really need a wheel lock. Transmission engagement issues surface repeatedly: the engine can stick in gear if the transmission is left engaged to stop the prop from spinning while sailing. The cockpit lockers are shallow due to the aft cabin intruding into that space. And while the B&R rig is structurally resilient, sailing dead downwind with a clean conscience takes some mental adjustment. Most of these issues are dealer-correctable under warranty, and owners consistently report their Hunter dealers addressing problems at no charge — but the density of first-season squawks is higher than on some comparable boats.
The Verdict
The Hunter 310 is a boat built around a coherent idea: that a thirty-foot cruiser should be easy to sail, comfortable to live aboard, and accessible to owners who want performance without intimidation. The B&R rig, circular cockpit, and thoughtful accommodations largely deliver on that promise. Where the boat falls short — light-air sluggishness, below-average downwind versatility, a noisy engine box in the saloon, and a higher-than-average rate of first-season defects — those compromises are knowable in advance and mostly manageable once understood. For coastal cruising with family crew, it is a genuinely capable and livable design. For passagemaking or bluewater voyaging, the cabin top riddled with hatches and windows, the high sill where a bridge deck should be, and the cockpit well that will take a long time to drain make it a less suitable choice.
Pros
- Exceptional cockpit ergonomics with the circular well, integrated arch, and rack-and-pinion steering
- Genuine two-stateroom privacy with solid doors fore and aft
- B&R rig eliminates backstay and enables full-batten main with lazy jacks — genuinely easy single-hand sail handling
- Long waterline (28 feet) and light displacement give good hull-speed potential in moderate to fresh breeze
- Solid construction with thorough hull-to-deck bonding and well-engineered grid reinforcement
Cons
- Light-air performance is notably weak, particularly in the shoal-draft version
- Swept-back spreaders compromise dead-downwind sailing comfort and safety
- Freestanding engine box generates significant noise and vibration at the center of the main living area
- First-season defect rate is higher than competitive alternatives — gauges, cables, head, mast gasket
- Not suited to offshore or bluewater use given drainage, freeboard hatching, and absence of a proper sea berth
