Hull form can be categorized as planning hull according to International Maritime
Organization’s (IMO), International Code of Safety for High-Speed Craft 2000 (2000 HSC
Code). Guidance of determined main dimensions, suitable sample form selected from Maxsurf
Modeler’s library and manipulated according to the requirements. Additional hydrodynamic lift
that support planning regime, one chine was added into the hull form. All engineering
calculations were completed by using Maxsurf program.
Equipment was selected based on MCA Brown Code, International Regulations for Preventing
Collisions at Sea (COLREG),1972 and International Convention for Safety of life at Sea
(SOLAS),1974 [8, 9]. Additionally, navigation lights were located according to COLREG-72.
Main engine is the key element of the vessel that determines speed, weight, fuel consumption
and initial cost. Optimal engine option for certain course speeds which were mentioned at
resistance calculations, is searched. Then suitable engine options were compared and best fit for
this study which is Yanmar 6BY3-220 was selected.

Figure 1. General arrangement
Fuel tank capacity was determined by estimated fuel consumption data based on resistance
calculations. Selected main engine consumes 20 liters diesel per hour at fast course that means
0.615 liters per knot. Even at fast course to ensure 500 nautical miles range 300 liters fuel tank
was placed.
