“…Experimental is very important for designs with good hydrodynamics, both of performance and safety. Experimental for multi hull ships was first performed by [2] on a catamaran to obtain optimal hull with minimum resistance, and also by [3] - [7]. Next [8] had analyzed with towing test for Wave Cancellation Multihull (WCM) on Trimaran.…”

One of the most essential aspects of ship is its resistance. There much have been done researches to analyze the reduction of resistance in order to get a good performance; yet the multihull is still one of interesting researches to get the rightest configuration, as to produce minimum resistance. This research is experimental study to obtain the lowest resistance with configuration consisting of stagger, clearance and trim of pentamaran. The pentamaran are performing as a trimaran formation by using Wigley hull with combinations transom on main hull and non-transom on side hulls. Its purpose is also to determine the destructive effects caused by wave interference. The research test conducted on stagger (a ratio of distance of stern main hull to stern side hull to main hull length)-positioning variations of 0.35 and 0.4. As for clearance (a ration of distance centerline of main hull to centerline of side hull to main hull width)-positioning variations, they exceed 1.05; 1.20; 1.35; and 1.50. The trim variations researched are 0°; 0.5 °; and 1.0 °. The result of this study was presented by tables and graphs of resistance components of side hull on stagger-clearance and trim condition.

“…The slender hull as known as Wigley (parabolic hull) from research by [6] on catamaran, trimaran, quadrimaran (tetramaran) and pentamaran. As well as [7] - [12] by determining the configuration of multihull on optimum distance of Wigley hull such as: catamaran, trimaran and tetramaran, with and without longitudinal of stagger. The studies of configurations of Wigley hull form on multihull has been proven effective in resistance deduction.…”

An optimum design of ship is to achieve the required speed with minimum power requirements. On multihull, sidehull position against to mainhull influences the friction resistance and its stability. Frictional resistance of multi-hull increases due to the addition of wetted surface area of hull, but wave making resistance can be lowered by a slender hull form. This research are experimental tests of trimaran with five Wigley hulls on a combination transom and without transom. The test varied on stagger, clearance and trim at several speeds. A ship with formation arrow tri-hull on forward was given to prove the resistance reduction due to cancellation wave which was indicated by negative interference. The influence diverse position of sidehull has shown that model non-transom (NT) stern moreover give beneficial resistance than model with transom (WT) at high speed. Similarly, in the trim conditions that NT more favorable on trim specifically for high speed depending on the position of the sidehull to the mainhull.
