Hull Design and Deck Layout
Glen Henderson's signature hollow bow was carried forward from earlier generations, its concave entry reducing pitching motion in a chop. The notable departure was the addition of a hard chine placed at the waterline, rather than above it — a decision that trades the visual drama of an elevated chine for a practical gain in form stability and lateral resistance when the boat heels. Beam is carried well aft to maximize interior volume, a Henderson trademark that defines the boat's spatial character below as much as it does its on-the-water behavior.
On deck, the redesign compresses a series of small, cumulative gains into a noticeably more ergonomic package. The cockpit pedestal moved aft creates a larger working area, and a hinged transom cutout folds down to form a swim platform that simultaneously opens more cockpit space and allows the main cabin to push further aft. The twin sculpted seats in the aft pulpit extend the social footprint. Halyards and furling lines lead aft to ganged Spinlock clutches at each side of the companionway, with molded line bins keeping tails clear of feet. Lower shrouds moved well inboard open the passage forward and allow the 110-percent furling jib to sheet cleanly outboard of the lower shroud and inside the upper, producing a tight sheeting angle that complements the fractional rig.
Rig and Sail Plan
Henderson's fractional rig with a 110-percent furling jib is the performance heart of the boat, designed to be tacked easily and to put sail area where a shorthanded crew can manage it. The main choice in sail plan divides buyers: the in-mast furling option simplifies weekend sailing dramatically, while the full-battened fat-head mainsail on a shorter, lighter mast adds meaningful horsepower and is the faster option by a significant margin. Hunter's overhead arch delivers dual-ended mainsail sheeting, and end-of-boom sheeting is retained over mid-boom configurations because it minimizes loads on hardware and crew.
The in-mast furling version carries a caveat. With no vertical battens, the sail plan loses power, particularly in light air, and a Code 0 asymmetrical will be a worthwhile investment for owners who find themselves sailing in anything below ten knots. Most of the running rigging hardware is Seldén throughout, including the top-rated Furlex for jib furling and bullet blocks for mainsheet loads — equipment that has performed reliably in independent testing.
Performance Under Sail and Power
Despite the modest sail area of the in-mast furling configuration, the 33 moves with more verve than its layout-first reputation might suggest. In 5 to 7 knots of breeze with the furling rig, the boat held an honest 5.5 knots hard on the wind. The helm was exceptionally well balanced even off the wind, and the boat accelerated cleanly in puffs. The balanced spade rudder allows the boat to turn nearly in its own length under power, an attribute that makes close-quarters maneuvering in a marina genuinely manageable.
The standard engine is a 21-horsepower Yanmar; the Mariner Package upgrades this to the 29-horsepower 3YM30 with saildrive. Under power, the test boat reached 6.5 knots at a comfortable cruise setting and 7.3 knots at wide-open throttle with a clean wake. The saildrive does reduce underwater drag relative to a conventional shaft and offers some noise reduction, but it introduces a maintenance discipline that owners must take seriously.
Interior Accommodations
This is where the Marlow-Hunter 33 makes its most compelling case. Two private cabins — a forward V-berth and a starboard quarter aft cabin with a larger-than-queen-size berth — are separated by a full-size midships head and shower, providing genuine privacy in 33 feet of waterline. Headroom reaches 6 feet, 2 inches in the main saloon, and the companionway steps were angled so that one descends facing forward with excellent handholds on either side.
The galley achieves a legitimate U-shaped arrangement, a configuration normally found on larger boats, with Corian countertops, a gimbaled two-burner Force 10 stove and oven, and a single deep sink. The dinette table conceals a hand-crank mechanism that lowers it to form a full-length berth, and the center section of the starboard settee flips to create a cocktail table or small chart surface. White foam-backed overhead panels are held in grooved plastic track and can be removed to access deck hardware, allowing through-bolted fittings with proper backing plates throughout.
Known Issues and Buyer Cautions
Two engineering decisions warrant specific attention. The saildrive demands annual haulout, zinc replacement, and close monitoring of the aluminum lower unit's paint coating for signs of corrosion. Copper-loaded bottom paints on the drive are categorically incompatible, and owners in warm climates who stretch haulout intervals risk accelerated corrosion. Practical Sailor's reviewers noted a preference for a conventional shaft system for long-term reliability.
The standard keel is iron. A lead keel was offered as an option and is worth the premium for any buyer contemplating offshore passages or wanting better long-term resistance to osmotic damage at the keel joint. The anchor locker is relatively shallow, a poor match for carrying substantial rode or a second anchor, and the stern cleats are vertically oriented, making them less accessible and poorly aligned with typical dock loads. The 25-gallon polyethylene fuel tank is functional but not ideal; high-grade aluminum is the preferred material for long-term integrity.
Refits and Upgrades
The most impactful upgrade for any example with in-mast furling is a Code 0 or asymmetrical spinnaker, which transforms the light-air performance envelope. Owners seeking better sail shape on the standard rig can upgrade to a full-battened mainsail on the shorter, standard mast — the single most cost-effective performance improvement available. Boats fitted with the standard iron keel benefit from vigilant monitoring of the keel-to-hull joint; upgrading to lead at a later stage is less practical than specifying it new.
For the saildrive, the exhaust elbow deserves regular inspection given the aft-facing engine orientation, which places service points in the aft stateroom rather than the engine compartment. Upgrading from the standard front-opening, minimally insulated refrigerator to a top-loading unit with better insulation is a near-universal improvement for anyone spending nights away from shore power. The Lewmar No. 30 winches found on the Mariner Package are a meaningful step up from the standard No. 16s for anyone sailing short-handed.
The Verdict
The Marlow-Hunter 33 succeeds at its stated purpose: delivering a two-cabin, full-amenity coastal cruiser in a hull that is genuinely enjoyable to sail. Henderson's fractional rig and well-balanced rudder make the boat feel lively rather than lethargic, and the interior is a legitimate achievement in spatial planning at this length. The caveats are real but manageable — the saildrive requires a committed maintenance routine, the iron keel is a second-best choice, and the in-mast furling mainsail extracts a performance tax in light air. Buyers who choose carefully among the option packages and commit to the annual haulout discipline will find an honest, well-designed coastal cruiser with enough interior comfort to keep a family aboard and enough sailing manners to make the passage worthwhile.

Cons
- Saildrive demands annual haulout and strict paint/zinc discipline
- Standard iron keel is an inferior choice to the lead option
- In-mast furling mainsail sacrifices meaningful light-air performance
- Shallow anchor locker limits rode capacity and second-anchor stowage
- Vertical stern cleats are awkward and misaligned with dock loads
