About the COMPIS 28
Designed by Bernt Andersson and built by Compisbåtar/Scanmar AB in Sweden, the Compis 28 is a classic Scandinavian cruiser with a production run spanning 1968–1983. A total of 600 hulls were constructed during this period, establishing it as a well-documented and accessible entry into vintage sailing.
- Best for:
- This boat suits coastal cruisers and weekend sailors who prioritize a manageable 28-foot footprint with a comfortable interior layout. Its moderate performance metrics make it ideal for relaxed sailing rather than high-performance racing.
- Bluewater capability:
- With a displacement of 6834.0 lb and a capsize ratio of 1.97, the Compis 28 is primarily designed for coastal cruising rather than extended offshore passages.
- Comparables:
- Comparable boats include the Tartan 27 and O'Day 28, which share similar dimensions and eras. These vessels offer similar displacement and beam characteristics, providing a benchmark for interior volume and handling in the late 1960s to early 1980s market.
