Centa carbon-fibre shafts. Some 70% of weight has been saved compared to that in the use of conventional steel shafts. Securing reliable and economical power generation on board are four MAN D2876 LE301/HCM 534C 360kW alternators.


Speed, seakeeping, and safety Sea trials for Natchan World were completed in an impressive two days with all systems performing perfectly and meeting best expectations. During the course of trials while running at 100% MCR speeds of 44knots were averaged with 220tonnes deadweight on board. Loaded with 560dwt an average speed of 41.9knots was achieved at 100% MCR, with T-foil deployed. In terms of


seakeeping the 112m offers significant improvements over


the already excellent 98m class due to increased hull separation, increased vessel length and mass, together with an increase in tunnel height and refined arch form. Enhancing the 112m wave piercing


catamaran’s already excellent sea keeping qualities is the Maritime Dynamics/ Incat Ride Control System, consisting of transom mounted trim tabs and a retractable T-foil. These, combined with Incat’s unique


hull form featuring long outer bows, fuller midship sections, stern skeglets, and centre bow clearances, means motion sickness incidence has been reduced in higher sea states by reducing pitch, roll, and heave, the major contributors to passenger discomfort. As always, safety is paramount and
