As for its predecessor, the basic concept is a planing hull with a wide stern, double rudder, sharp edges and a canting keel. A new feature is the reverse bow. It lengthens the waterline and reduces the pitching in short waves. However, it provides plenty of spray on deck. The lateral plan has also been revised. The VO65’s daggerboards do not have an angle of attack but instead the VO65 uses a buoyancy profile to counteract drift.
Weight was saved due to a lower load on the daggerboard boxes and also the mechanics for raising and lowering the daggerboards have been simplified. The 4.78 metre long keel is slightly inclined forwards by five degrees. When the keel is swung to windward, this five-degree inclination causes an angle of attack that provides buoyancy, which reduces displacement, and thus water resistance, stabilizes the bow in waves and also prevents some drift. The VO65 also has a longer bowsprit and three water ballast tanks.
