It is 22’ - 6” x 8’ - 5” over the hull, it has a full bow and semi elliptical stern with a deep sheer strake all round to take large fendering. The hull is full bodied, of the double chine form, and designed for ballasted displacements of over 4 tonnes. There is a deep keel with space to swing a large diameter propeller, in a shallow tunnel if necessary, with a skeg to protect the stern gear and r
udder. Although intended for operation at displacement speeds with good bollard pull the hull has a relatively flat run aft so that at lighter displacements and with suitable power it is capable of running at slightly higher speeds. The hull design has been based on a series of similar workboats and although this version is being produced in grp the design is also suitable for building in alloy and steel.
