Design and Construction
Jeppesen's hull form is a moderate-displacement monohull of 9,700 pounds, a 10.8-foot beam, and a 28.2-foot waterline, giving a length-to-beam ratio of 3.37 and a displacement-length ratio of 192 that places her among moderate racers rather than heavy cruisers. The ballast ratio sits at 42 percent, and the balsa-cored sandwich hull was specified to improve the indoor climate, a detail that separates her from solid-laminate contemporaries. Both hull and deck are fiberglass, but the builder also sold the model to be home-completed, meaning individual boats may vary in execution. That variation is worth holding in mind when assessing any single specimen, since yard-finished and amateur-finished hulls share only the structural concept.
Rig and Performance
The fractional sloop rig carries 571 square feet of sail, and the sail-area-to-displacement ratio is 19.7 on the ISO reference sail, rising to 22.5 with a 135-percent genoa. Those figures, paired with the 192 DL-ratio, describe a boat that is lively without being extreme. The theoretical hull speed is 7.1 knots, while a calculated maximum of about 4.0 knots appears in the record alongside a Relative Speed Performance of 82. The capsize screening value is 2.03, a number that would bar her from sanctioned ocean races, and the Motion Comfort Ratio is 20.3 with an immersion rate near 189 kg/cm. The wetted surface is about 355 square feet, and draft runs 6.07 to 6.37 feet depending on load, which restricts her to major marinas.
Accommodations
Inside, the Ravage 36 offers above-average headroom and a mahogany interior in the manner of many boats of her era. The same balsa sandwich that tempers the cabin climate also supports a livable volume within the 36-foot envelope. What is established is that the cabin is built to be stood in comfortably and finished in a traditional hardwood rather than laminate.
Known Issues
The principal caveat is the home-completion program, which introduced potential quality variance between hulls, and the saildrive leg, which on any used example merits close inspection for seal and corrosion history. The balsa core, if ever breached by fasteners or impact, carries the usual sandwich-boat risk of moisture ingress.
Refits and Ownership
Ownership considerations center on the small production run and the mixed provenance of the fleet. A buyer or owner evaluating a Ravage 36 should establish early whether the hull left Bianca A/S or another yard, or was finished privately, since that bears on consistency of structure and systems. The saildrive and lead fin keel are straightforward to service where records exist, and the modest wetted surface keeps antifouling area manageable.
The Verdict
The Ravage 36 is a thoughtfully proportioned late-1970s design from a reputable Danish builder, with a performance profile that rewards sailed area and a comfortable, climate-conscious cabin. The limited build and home-completion option make individual inspection essential, but the core concept is sound.
Pros
- Balsa-cored hull specified to improve cabin climate
- Moderate-racer proportions with genoa-driven sail-area ratio of 22.5
- Above-average headroom with traditional mahogany interior
Cons
- Home-completion history introduces quality variance between boats
- Draft of 6.07–6.37 ft limits marina access
- Capsize screening of 2.03 excludes sanctioned ocean racing
