Design and Construction
Eivind Still's late-seventies hull measures 33.2 feet overall with a 26.25-foot waterline, a 10.63-foot beam, and a length-to-beam ratio of 3.12. The boat is built of solid fiberglass in both hull and deck, carrying a lead fin keel and a spade rudder. At a displacement of 10,582 pounds with 5,071 pounds of lead ballast, the ballast ratio sits at 48 percent, and the displacement-length ratio of 272 places her firmly among what the design data call heavy cruisers. That mass is paired with a wetted surface of about 333 square feet and an immersion rate of 972 pounds per inch, meaning she rides deep and settles predictably under load.
Rig and Handling
The Finnfire 33 is a masthead sloop carrying 462 square feet of sail area. With the ISO reference sail her sail-area-to-displacement ratio is 15.7, rising to 19.0 with a 135 percent genoa. Against her peers she is slightly underrigged, showing more sail plan than only 27 percent of similar boats. The theoretical hull speed is 6.9 knots, while the calculated maximum under engine is about 4.1 knots. The capsize screening value is 1.91, and the Motion Comfort Ratio is 25.6, figures consistent with a stable, damped motion profile rather than an edgy performance hull. Her draft runs 6.07 to 6.37 feet depending on load, which limits her to major marinas. The standing and running rigging follows period masthead proportions: all halyards are 99.8 feet long at 3/8 inch diameter, sheets run 33.2 feet at 1/2 inch, and the mainsheet is 83 feet long at 1/2 inch.
Accommodations
The 10.63-foot beam and 33.2-foot length define the envelope within which the cruising layout was arranged.
Known Issues
The single operational caveat concerns draft: at 6.07 to 6.37 feet loaded, the hull cannot reach shallow anchorages and requires major-marina depth.
Refits and Ownership
With production ending in 1982, any surviving Finnfire 33 is now decades old, and the masthead rig's halyards and sheets are standard lengths and diameters, so running-rig renewal is straightforward. The lead keel and solid laminate hull present no exotic construction requiring specialist repair knowledge.
The Verdict
The Finnfire 33 is a small, heavy, well-ballasted cruiser of limited production, designed by a named Finnish architect and built by a Finnish yard. Her numbers describe a stable, underrigged, comfortable boat suited to coastal cruising from deepwater berths rather than gunkholing.
Pros
- High ballast ratio (48%) and heavy-cruiser displacement for a 33-footer
- Lead fin keel and solid fiberglass construction
- Comfortable motion profile (Motion Comfort Ratio 25.6)
Cons
- Draft of 6.07–6.37 ft limits marina and anchorage access
- Slightly underrigged versus similar sailboats
- Only sixty built, so spares and comparable boats are scarce
