About the CORK 1720
The Cork 1720 is a 26.25 ft fractional sloop designed by Tony Castro and built by 1720 Yachts (UK) in 1994. With a displacement of 3003.0 lb and a beam of 8.17 ft, this lightweight cruiser-racer offers a SA/D ratio of 27.59, prioritizing speed and agility over heavy offshore comfort.
- Best for:
- This boat suits coastal cruisers and club racers who value performance and ease of single-handed handling, given its light displacement and fractional rig.
- Bluewater capability:
- With a low D/L ratio of 106.12 and a comfort ratio of 11.69, the Cork 1720 is best suited for protected coastal waters rather than extended bluewater passages.
- Comparables:
- Comparable boats include the O'Day 262 and Pearson 26, which share similar dimensions and roles as lightweight, performance-oriented coastal cruisers from the same era.
