HH Catamarans OC50 - 2021 51' 9" HH CATAMARANS
United States POA
What makes the OC50 unique is its ability to sail a percentage of the wind speed much higher than other cruising cats. The OC50 is a true performance cruising catamaran all the while offering top level construction and accomodations.
A typical 50' cruising cat may average around 7 knots or so on a circumnavigation. Expect higher numbers with the OC50. Perhaps you can be the first to give us that data. As of now the preliminary data is excellent. See the photos of the B&G displays.
What makes the boat different? Well, first its the design prowess of Morelli and Melvin and the exacting standards of the engineers and staff of HH Catamarans. The HH brand accommodates the small niche of people who demand performance, quality, and high-end accommodations.
Equally important is the experience of Rocknak's to guide you through the build. We have visited with, and know, the key personnel at the factory on a first name basis. Rocknak's has the capability to train you in your boat and provide service and support while you own your new OC50. Ask for recommendations.
On your first sea trial you will find the boat turns quickly, is stable, points much higher than what you have been accustomed to on charter cats, and can be maneuvered easily in port.
The boat is predictable, has excellent bridge deck clearance, and exudes quality. Inquire how to see the boat yourself. You will see why visitors at the boat shows and those that have been aboard say the HH Catamaran is their favorite.
