look and feel of being new and exciting. To reduce the boxy look of high freeboards that many other 40ft catamarans suffer from, for example, the topside windows with integrated portlights are continuous along the hull and the dark colored moulded swoosh-shaped impression extends to the transom.
The low angles of the deckhouse sides not only reduce aerodynamic drag, but are designed to create a sleek, functional look to the structure, while also providing adequate cover from the elements, whether it’s spray or sun.
Efficient sailing systems Performance has always been an important factor in the development of HH Catamaran designs and the HH44 is no exception. And it’s more than just having an appropriate power to weight ratio in the sailplan to make the boat come alive when sailing, but also having the efficiency and functionality in the sail control systems to make sailing easy and fun for a limited number of owner/crew that would typically be aboard a boat of this size. First, the sailplan supported by the Marstrom-built carbon spar and rigging is generous: 125.3m2 of upwind sail area with the main and solent jib, which expands to 223.1m2 of downwind sail area with the addition of the 148.9m2 gennaker or 109.7m2 reacher. For a 13.4m length and only 12,500kg of full-load displacement this is an impressive power to weight ratio for any boat in this class. ‘Our hulls are always designed to handle their payload well,’ says designer James Hakes, ‘so you will see the speed does not dramatically reduce at full load.
Secondly, the main traveller location on the roof is out of the way but still accessible when needed, controlled via push buttons at each helm station. Thirdly, the headsails and gennaker are on low-friction furler systems that are accessible and able to deploy and douse with a short- handed crew, with all furling lines led back to the aft helm stations. Fourth, all lines, sheets, halyards led from the mast underdeck with winch and clutch placement at the helm stations make for easy shorthanded sailing. The helm pedestal’s ability to pivot inboard or outboard is also a great feature to enhance visibility or duck out of the sun or weather.
Unlike their larger brethren, HH44s will not be built with full carbon hull skins as this does not offer a weight reduction at this size, but resin-infused E-glass and M

viewed from above, the HH44 has some key hallmark features of a fast and seaworthy design:
witness the wide but relatively
short platform and slender hulls with very fine
entries. Note also the vast array of solar panels on the cabin top, which can produce almost as much power in some conditions as a diesel genset
How fast will it go?
VPP analysis by KND in Valencia indicates that in a racing displacement mode of 10,900kg, the HH44 should achieve the following figures:
TWS 46-50 6
10 20
5.35 7.71
12.43
And for full-load trim: TWS 46-50 10

5.03 7.57
12.09 80 8.41

Foam composite epoxy laminates with a carbon skeleton comprising of all bulkhead, stringers, beams and reinforcing for loaded areas – Hakes says there is little to gain to justify the material cost of using 100 per cent carbon in a boat this size. A mix of quality composite materials is most appropriate with this platform to keep the costs realistic. Nonetheless, carbon is used throughout the boat where its strength and light weight is ideally suited to the engineering integrity of the structures… such as the monocoque longeron, martingale and truss structures that tie together the loads from the hull bows to the spar through the headstay. This critical part also features an anchor and tackle deployment system in a clever design of combined functions into one integrated part.
There are numerous other clever design features on the HH44 that make for functional versatility without compromise on performance. Such as: l Large, flat windows that open for flow-through ventilation under the canopy l Standard fold-down steps and swim platform on the sterns for easy access when deployed and safe enclosure of the cockpit and saloon area while sailing

l An optional side boarding gate for direct side access from dock to aft deck l Fold-down helm station seat, available if needed and out of the way when not l Curved carbon daggerboards that increase upwind and reaching performance, retract for slippery downwind performance and are positioned to have minimal impact on interior hull volume
Eco-friendly parallel hybrid power
Another important innovation in the HH44 is that the entire cabin top is covered in solar panels. This is not an add-on afterthought, but designed and built to be integral to the concept of achieving environmental sustainability while retaining functionality of the boat’s propulsion and power management systems. These solar panels are highly efficient, delivering 3.2kW of electrical energy with the option of adding more to provide another ½kW of energy. These power delivery figures are impressive and represent averages centered around mid- latitude weather conditions and not just in the tropical sun. Considering luxury yachts of this size are typically equipped with diesel generators that produce 5kW of energy, the weight w
