About the DOLPHIN 81
The sail plan includes 2 spinnakers, one at 7/8,(42m2/452 sq.ft.) and one masthead (70m2/753 sq.ft.).
The Dolphin 81 is a lightweight, performance-oriented fractional sloop designed by Ettore Santarelli and built by Maxi Dolphin Boatyard in Italy. With a production run limited to 1992 and an unknown total build count, this 26.57 ft LOA vessel is characterized by its low displacement of 2094.0 lb and high sail area-to-displacement ratio of 37.92.
- Best for:
- This boat is best suited for coastal cruising and daysailing enthusiasts who prioritize speed and ease of handling over heavy offshore protection. Its light displacement and high SA/D ratio make it ideal for single-handers or couples seeking a responsive, planing-capable day boat.
- Bluewater capability:
- With a low displacement of 2094.0 lb, a comfort ratio of 7.16, and a capsize ratio of 2.77, the Dolphin 81 is not recommended for extended bluewater passages due to its light construction and lack of heavy ballast.
- Comparables:
- Comparable vessels include other late-80s/early-90s European performance day-sailers like the Beneteau First 26 or J/26, which share similar fractional rig configurations and light-displacement hull forms designed for upwind efficiency.
