Novamarine 2, an Italy based yard, has a strong experience on inflatable boats, especially on maxi ones. The recent joint-venture with Fabio Buzzi, leading to the building of a high performance inflatable boat which has won several endurance races worldwide, is the strong background of the new HD Twelve Special, which is already considered a technological challenge to the inflatables boat market. Space, is the first impression boarding the HD Twelve Special and the boat's design ( which is completely open ) makes it even larger. The result is a roomy bow with a large sun-lounge and a beautiful all purpose teak swimming-platform, generously dimensioned.

High construction standards, from fiberglass manufacturing to hull's fittings assembly, is the philosophy reflected on the yard's production range and can be appreciated on this new maxi-inflatable boat as well. Fiberglass moulding, on board plants, stainless steel works and many other parts, are manufactured by the yard itself, thus ensuring functionality and durability throughout the years. Cleats, dashboard grabrail, and all the stainless steel parts are manufactured according to an exclusive in-house process. An indelible protective paint is applied, ensuring time lasting quality. The hull, purposedly designed for water-jets propulsion, achieves high performances offering a soft ride and course steadiness also with low-moderate swell.
