An exquisite amalgam of style, speed and manageability, the HH55 is a fast, ocean-ready yacht prepared to sail anywhere in the world.

Designed and engineered by the highly successful design team of Morelli & Melvin, the HH55 is a boat that is safe and easily handled by just two people for short-handed sailing. There is also a lot of room for customisation and personlisation with both 3 or 4 cabin layouts and additional interior styling options. The spacious saloon flows into a large aft cockpit which features the safety of full visibility from the aft help stations, or alternatively, the central command of the forward helm station.

In keeping with our commitment to a high level of luxury and performance, the HH55 is an all carbon affair. Rig, Hulls and structures all enjoy the superior safety and weight saving properties that only carbon can offer. Like her sister ship, the HH66, the HH55 has a curver "C" daggerboard and T-foil rudders, giving greater performance and a smoother ride in the waves.

This is a very fast boat that is truly ocean ready to take you anywhere your heart desires as her very happy owners will testify!!
