About the FINNGULF 33
A new, entirely different FINNGULF 33 was introduced in 2000. (here listed as FINNGULF 33-2) The FINNGULF 33 is also known as INFERNO 33.
Designed by Håkan Södergren and built by NaBoats/Tabasco Marine in Finland, the Finngulf 33 is a robust fractional sloop with a production run starting in 1988. With a displacement of 9920.0 lb and a D/L ratio of 227.51, this vessel offers a heavy, stable platform that prioritizes seakeeping over pure speed.
- Best for:
- This boat is ideally suited for coastal cruisers and those seeking a comfortable, stable day-sailer or short-range cruiser, given its moderate comfort ratio of 24.53 and manageable LOA of 32.97 ft.
- Bluewater capability:
- While its low capsize ratio of 1.88 and fin keel with 5.74 ft max draft suggest decent offshore stability, the reported structural issues with keel smiles and hull blisters require careful vetting before considering extended bluewater passages.
- Comparables:
- Comparable vessels include other late-80s European heavy-displacement cruisers like the Hallberg-Rassy 33 or Nauticat 33, which share similar fractional rig configurations and substantial ballast ratios for stability.

Near-identical models — same hull, builder and designer, re-badged or lightly changed. Specs and owner-reported issues are typically shared across the group, so a sister model's page may carry detail this one doesn't.
