<p>It concerns a hull made up of three (3) sections of different draught, width and design each. The front section (F) is larger than the middle (M) and the rear section (R), while the middle is larger than the rear. The hull sections are divided between them by a transverse rib (5). In the front, instead of having stabilizer fins, there are four oblong ribs (3) on each side. In the middle there are three oblong ribs (3) while in the rear there is one oblong rib (3) and two stabilizing fins (6) on each side. The advantage of this invention is the acquired capability of the powerboat to achieve higher speed, with less power and fuel economy, as there is a great reduction in friction due to the hull's design.</p> |
