Summary Analysis of the Design Ratios for the Hanse 455
1. A Sail Area/Displacement Ratio of 20.1 suggests that, in the right hands, the Hanse 4550 will have enough performance to leave most other sailboats of similar waterline length well astern.
2. A Ballast/Displacement Ratio of 30.2 would usually mean that the Hanse 455 would have a tendency to heel uncomfortably in a gust, and need to be reefed early to keep her sailing upright in a moderate breeze.
However, as she has much of her ballast concentrated in a bulb at the foot of her keel, she's likely to be considerably stiffer than her published Ballast/Displacement Ratio might suggest.
3. A Displacement/Length Ratio of 178 tells us the Hanse 455 is a light displacement sailboat. If she's loaded with too much heavy cruising gear her performance will suffer to a degree.
4. Ted Brewer's Comfort Ratio of 27.5 suggests that crew comfort of a Hanse 455 in a seaway is similar to what you would associate with the motion of a coastal cruiser with moderate stability, which is not the best of news for anyone prone to seasickness.
5. The Capsize Screening Formula of 2.1 tells us that a Hanse 455 would be a better choice of sailboat for ocean passage-making when compared to a sailboat with a CSF of less than 2.0.
The Hanse 455 is no longer in production. It was discontinued in 2017, after three years of manufacturing. The exact number of units built is not publicly available, but according to some sources, there were more than 200 Hanse 455s sold worldwide.
The builders of the Hanse 455 are Hanse Yachts, a German company founded in 1990 by Michael Schmidt, a former Olympic sailor. The company started as a small boatyard in Greifswald, on the Baltic Sea, and soon expanded to become one of the largest yacht manufacturers in Europe. Hanse Yachts is known for its innovative designs, high-quality craftsmanship, and customer-oriented approach. The company is still in business today, producing a range of sailing yachts from 31 to 67 feet, as well as motor yachts under the brands Fjord and Sealine.
The Hanse 455 has three keel options:
- a standard L-shaped keel with a medium draft of 2.19 m (7.2 ft),
- a shallow keel with a draft of 1.82 m (5.12 ft), and
- a T-shaped keel with a deep draft of 2.25 m (7.5 ft).
The interior of the Hanse 455 is spacious and bright, with large windows and hatches that provide natural light and ventilation. The interior design is modern and stylish, with a choice of wood finishes and fabrics. The saloon is the central area of the boat, with a U-shaped sofa and a large table on the port side, and a long sofa and a navigation station on the starboard side. The galley is located aft on the port side, and has a double sink, a three-burner stove, an oven, a fridge, and plenty of storage space. The Hanse 455 has a standard layout of three cabins and two heads, with the owner's cabin forward and two guest cabins aft. The owner's cabin has a double island bed, a wardrobe, and an ensuite head with a separate shower stall. The guest cabins have double beds and share a head with a shower on the starboard side. The Hanse 455 also has an optional layout of four cabins and two heads, with two smaller cabins forward and two larger cabins aft.
The exterior of the Hanse 455 is sleek and elegant, with a low-profile coachroof and a flush deck. The cockpit is the main outdoor area of the boat, and it is unusually large for a boat of this size. It has twin helms with large wheels and instrument displays, a folding cockpit table with integrated chart plotter, and two long benches that can be used as sun lounges or extra berths. The cockpit also has a large bathing platform that can be lowered electrically to provide easy access to the water. The deck is uncluttered and easy to walk around, with wide side decks and flush hatches. The foredeck has a large anchor locker and an optional electric windlass. The aft deck has a storage locker for the liferaft or other equipment.
