The 23,249dwt Ice Class IA multi-purpose vessel Reestborg, completed last year by Ferus Smit for Wagenborg, illustrates one of the many new hull forms being developed to reduce resistance, the design in this instance featuring a bulbless bow with negative stem profile along with sharp entrance angles and reduced bow flare.
This combination, used in conjunction with a ducted large slow-running propeller and an engine of 4,350kW output, provided a service speed of 14.5 knots on the 14,141gt ship’s initial outing when she carried 16,500 tonnes of iron ore between Hargshamn, Sweden and Hamburg, Germany on a draft of 26.2ft.
