About the INFERNO 29
The Inferno 29 is a fractional sloop designed by Håkan Södergren and built by NaBoats (FIN) in 1982. With a displacement of 5732.0 lb and a comfort ratio of 21.12, this vessel represents a specific era of Finnish boatbuilding, though the exact number of hulls built remains unknown.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a manageable 28.87 ft LOA and a moderate 4.92 ft max draft for access to varied shorelines. Its fractional sloop rig and 20.54 SA/D ratio suggest it is well-suited for those seeking a balance of performance and ease of handling.
- Bluewater capability:
- With a capsize ratio of 1.84 and a displacement of 5732.0 lb, the Inferno 29 is primarily designed for coastal cruising rather than extended bluewater passages. Its fin keel and moderate ballast ratio suggest stability in moderate conditions but limited heavy-weather offshore endurance.
- Comparables:
- Comparable boats from the early 1980s with similar fractional sloop rigs and moderate displacement include the Benetele First 28 and the O'Day 28. These models share similar dimensions and roles, offering a mix of cruising comfort and sailing performance.
