About the IDEA 11
The Idea 11 is a 36.09 ft masthead sloop designed by Scott Kaufman and built by Cantiere Alaver (ITA) in 1979. With a displacement of 10585.0 lb and a beam of 11.65 ft, this vessel represents a specific era of Italian construction with a single-year production run.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a comfortable, stable platform with a moderate comfort ratio of 19.53. Its dimensions and rigging make it manageable for couples or small families seeking a manageable cruising experience.
- Bluewater capability:
- With a capsize ratio of 2.13 and a displacement of 10585.0 lb, the Idea 11 offers reasonable offshore stability, though its single-year production and limited build history suggest verifying structural integrity before extended bluewater passages.
- Comparables:
- Comparable boats from the late 1970s include other Scott Kaufman designs and contemporary 36-foot fin-keel sloops with similar displacement-to-length ratios. These vessels share the same era's emphasis on interior volume and moderate performance characteristics.
