The design optimization of a fast monohull, including her behavior at high forward speed in head waves, is the focus of the work presented in this paper. One of the possibilities to improve the seakeeping behavior in waves of a fast monohull at reasonable cost, apart from raising the deadrise, is to make use of the socalled 'enlarged ship' concept. In this concept the length of the hull is increased considerably (i.e. approx. 25- 50%) in particular forward of the accommodation and no changes are made to the 'payload' functions and the layout and interior of the ship. In this paper the authors have applied this 'enlarged' ship concept on an existing semi-plannig fast patrol boat (Royal Hong Kong Police 'King Clss 26 m., speed 25 knots). Along with the basic design with a length of 26 m. (100%) another two (enlarged) design alternatives have been introduced with respectively 33 m. (125%) and 40 m. (150).
