About the GUY 33
The Guy 33 is a fractional sloop designed by Guy-Christer Lönngren and built in 1977, with an unknown total hull production count. It is a 33.2 ft LOA vessel with a displacement of 7496.0 lb and a comfort ratio of 19.65, reflecting a design focused on balanced performance and seakeeping.
- Best for:
- This boat suits coastal cruisers and short-handed sailors who prioritize a responsive, fractional-rigged sloop with moderate displacement for manageable handling. Its dimensions and rig type make it well-suited for those seeking a classic 1970s cruiser that remains active in the market.
- Bluewater capability:
- With a capsize ratio of 1.98 and a displacement of 7496.0 lb, the Guy 33 demonstrates solid offshore stability and seaworthiness for coastal and nearshore cruising. Its fin keel and fractional rig provide good performance, though its age requires careful structural assessment for extended bluewater passages.
- Comparables:
- Comparable boats include other 1970s European fractional sloops of similar length and displacement, such as the Hallberg-Rassy 33 or Nautor's Swan 36, which share similar hull forms and performance characteristics. These vessels offer similar bluewater potential and interior volume within the 33-foot class.
