PILOT BOATS
DMC&A has been involved with Pilotage Authorities for many years, both designing vessels and as retained Consultant Naval Architects/Surveyors. The photograph shows the "St Nicholas", a 14.5 metre twin screw pilot launch, one of four operated by UK Pilotage Authorities to the "FRCV" design of DMC&A.

These vessels are designed to bridge the gap between fully planing and displacement vessels, combining as many as possible of the best characteristics of both types.

The FRCV hull form is sea kindly and exceptionally stable in roll, together with the ability to keep decks dry in conditions when a conventional displacement or semi-displacement vessel would be hampered by restricted visibility due to spray on the forward screens. The vessels are powered by twin 530hp turbodiesels and achieve speeds of up to 30 knots. A 16m variant on this design has been tank tested for waterjet propulsion at higher speeds.

Fendering developed especially for this class ensures that minimal damage is suffered during the "controlled collisions" which characterise pilot boarding operations.
