Automatic Humphree Trim for Seaway Pilots 

Comfort and performance with Humphree


Gladding-Hearn Shipbuilding, Duclos Corp. recently delivered a Chesapeake-class pilot boat to the Seaway Pilots Inc. in Cape Vincent, N.Y. The Seaway pilots navigate ships in and out of the ports and harbors of the St. Lawrence Seaway between St. Regis, N.Y., and Port Weller on Lake Ontario.

With a 4.8′ draft, the 53.6’x17.8′ all-aluminum pilot boat features the Ray Hunt Design Deep V hull. It is powered by twin keel-cooled Volvo Penta D16, EPA Tier 3-compliant diesel engines, each delivering 641 hp at 1,800 rpm. This gives the boat a top speed of 23 knots. A Humphree interceptor trim-tab control system, with automatic trim optimization is installed at the transom. Diesel capacity is 800 gals., which shipyard officials said will provide a range of at least 300 miles at an economical speed of about 20 knots.
