The world’s most effective ride control systems are installed on Incat Wave Piercing Catamarans to ensure passenger comfort and safety. The revolutionary, award winning retractable T-foil, positioned at the aft end of the centre bow, is used in combination with two transom mounted trim tabs providing ride control forces equivalent to a pair of keel mounted T-foils ensuring a smooth ride in heavy seas. The optional T-foil is used only when it is needed hence there is less drag to slow the ship, with resultant savings in fuel and less chance of the foil striking a submerged object. The T-foil can be retracted in calm seas and the ride control system switched off. In moderate seas the ride control system is activated and only uses the trim tabs with the T-foil still stowed inside the ship. In high seas, the T-foil is deployed and the full capability of the ride control system is brought to bear on maximising passenger comfort. Earlier Incat built ocean-going vessels prior to hull 56 were generally fitted with trim tabs and bolt-on T-foils, a few smaller craft operating on sheltered waters have trim tabs only. Flexible rubber mounts between superstructure and hull ensures a minimum of noise and vibration permeate the climate controlled passenger cabin, maintaining an atmosphere of relaxation and comfort.
