Unique Characteristics

The HH55 has a customizable interior. We work with you to create what meets your requirements. Finishes, fabric, and the selection of wood are all up to you.

The performance of the HH55 is remarkable in that sailing wind speeds can be achieved in several points of sail. This includes sailing in very light wind.

The specification list (inquire scott@rocknaks.com) includes equipment that is the best available. Combined with additional choices on an extensive selection of options each HH55 can be truly individual.

The HH Catamarans HH55 is for the discerning customer who desires the best performance with ultra-high quality and attention to detail.

The master cabin's berths on the HH55 are aft. This is a well ventilated area of the boat due to the forward, unimpeded flush-mounted opening hatch and side opening ports. The berths are standard height off the cabin sole and roughly that of a queen. Side windows, an aft "picture" window, and overhear hatches allow ample light and an open feel.

Forward cabins are close in size to the aft cabins. Each are also well ventilated, open, and airy. Its up to you to have the forward areas configured as cabins or utilize the space for part of a masters cabin or perhaps a workshop or utility room.

The cabinetry is best described by seeing the photographs or watching our videos in this listing. Keep in mind the video are of four cabin models. Please see the images or perhaps the HH50 interior video to see what a 3-cabin model would look like.

When entering the salon on the HH55's that are in sailing now, visitors have remarked on its size and unique accommodations. Again, the interior is up to you, however the boats that have been built so far include (2) Settees, and Island Galley, large forward facing Nav Station, considerable cabinetry, and a retracting large screen television monitor.

The Salon opens up to the Cockpit by sliding heavy duty megayacht quality doors. The cockpit becomes the salon and vice-versa.

A 3-cabin boat will have a large head and separate shower forward. The guest hull would have two heads with a center Jack-and-Jill shower.

A 4-cabin boat would have two heads per hull with the Jack-and-Jill showers.

See or video of the HH55's interior. The finish and fabric choices are yours.



Counter space is something there is plenty of in the HH55's delivered so far. The center island is a natural meeting spot and place to prepare food or drinks. Under the island are twin double pull-out refrigerator/freezer doors.

A builder with experience

Hudson Yacht Group has a large, modern facility located right on the water. Resin infusion, 5-axis routers, water jets, a giant autoclave, and traveling gantries are all part of this proper facility.

The magic, however, comes from the experience of the craftsman building the boat. Finishes that have depth and woodworking reflecting hundreds of years of tradition. Electrical assemblies and mechanical systems as a study in how its done. Hardware and component selection that is, well, state of this art.

Well known names in the performance boat industry can be working for you and your project! Consider the experience of Paul Hakes, Riccardo Marton, Thomas Jonsson, James Juan, Paul Smith, and Taka Wung. Smart, exacting, and dedicated to making the HH Catamaran the best available.

Ask Scott scott@rocknaks.com about build options and build locations (new).
