Sailpages Buyer's Take

The Maxi Dolphin 65 is a rare, high-performance fractional sloop designed by Luca Brenta and built by Maxi Dolphin Boatyard (ITA) in 1999, with only 5 hulls constructed. Its extreme sail area to displacement ratio of 30.46 and low capsize ratio of 2.03 reflect a design optimized for speed rather than heavy displacement comfort.

Best for:
This boat suits experienced sailors seeking a fast, coastal racer-cruiser who prioritize performance over heavy bluewater comfort, given its high SA/D ratio and relatively low comfort ratio of 23.23.
Bluewater capability:
With a displacement of 39617.0 lb and a capsize ratio of 2.03, the boat is structurally sound for offshore passage but its high sail area and low comfort ratio suggest it is better suited for coastal cruising than heavy ocean voyaging.
Comparables:
Comparable to other late-1990s high-performance fractional sloops like the X-Yachts X65 or early Nautor's Swan 651, as they share similar fractional rigs and emphasis on sail area over heavy ballast.
