Design and Construction
Lönngren's half-tonner carries a fin keel of lead and a solid fiberglass hull and deck, the sort of straightforward composite layup that rewards inspection rather than apology. The 5.77-to-6.07-foot draft band shifts with load, and the boat's immersion rate of about 904 pounds per inch tells you how little she asks of the water to change trim. A capsize screening value of 1.97 and a Motion Comfort Ratio of 19.5 place her firmly in the lively, seakindly-enough camp of late-1970s rule-cheaters rather than heavy displacement cruisers, while a wet bottom surface area of about 29 m2 (312 ft2) keeps her easily driven for her length.
Rig and Handling
What distinguishes the Guy 33 on paper is her sail plan. She was offered with more than one rig, either a fractional sloop or a masthead sloop, and the fractional option carries a working sail area of 419.9 square feet between main and jib. The boat is significantly overrigged against her peers — she carries more sail than 82 percent of comparable designs, and her sail-area-to-displacement ratio runs 17.5 on the ISO reference sail, rising to 20.9 with a 135 percent genoa. That excess canvas, paired with a Relative Speed Performance of 58 and a theoretical hull speed of 7.0 knots, explains why a displacement hull of this size feels quick on her feet. Under power, an inboard Volvo Penta 2002 diesel of 18 horsepower moves her at a 6.0-knot cruise and an 8.0-knot max, according to the design data.
Accommodations
Below, the Guy 33 is laid out as a practical six-berth, three-cabin arrangement with a galley and a toilet facility. Fresh water is carried at 40 liters and fuel at the same 40 liters, figures that suit weekend racing and short coastal hops more than extended autonomy. The interior volume is shaped by the narrow beam and racer origins, so the cabin plan serves function without pretense.
The Verdict
The Guy 33 is a late-seventies IOR half tonner that wears her racing breeding without compromise: overrigged, easily driven, and built of straightforward solid fiberglass with a lead fin. She rewards a sailor who wants a quick, hands-on 33-footer more than one seeking a floating condominium, and her modest tankage and narrow hull are the honest limits of that brief.
Pros
- Significantly overrigged for her size, with sail-area-to-displacement up to 20.9 under a 135% genoa
- Solid fiberglass hull and deck with lead fin keel and 40% ballast ratio
- Offered in fractional or masthead rig to suit owner preference
- 18 hp Volvo Penta 2002 gives 6.0-knot cruise, 8.0-knot max under power
Cons
- Only 40 liters each of fresh water and fuel capacity
- Narrow 3.44 length-to-beam ratio limits interior volume for six berths
- Motion Comfort Ratio of 19.5 suits coastal work over heavy offshore use
