About the KRAKEN 40
'Light weather rig' 950 sq.ft.(upwind sail area)
The Kraken 40 is a distinctive 1970 design by Lock Crowther, characterized by its lightweight 6000.0 lb displacement and 39.5 ft LOA. With hulls built by various manufacturers starting in 1970, this vessel represents a specific era of experimental yacht building that prioritizes speed and sail area over heavy displacement.
- Best for:
- This boat suits experienced coastal cruisers and performance-oriented sailors who prioritize high sail area-to-displacement ratios and are willing to manage the maintenance demands of a vintage, lightweight hull. It is less ideal for novice owners or those seeking a low-maintenance, heavy-displacement bluewater cruiser.
- Bluewater capability:
- With a low D/L ratio of 65.23 and a capsize ratio of 5.95, the Kraken 40 is primarily a coastal cruiser rather than a dedicated bluewater passagemaker, as its light displacement and high sail area demand careful handling in heavy offshore conditions.
- Comparables:
- Comparable boats include other 1970s lightweight performance cruisers like the O'Day 38 or early Catalina 30s, which share similar masthead sloop rigs and moderate beam dimensions. However, the Kraken's unique 27.0 ft beam and variable keel options distinguish it from more conventional designs of the era.
