This May the bow twin-screw tug Sea Coast undergone a repower with the Cats out and a pair of Tier 3 compliant Cummins QSK19-Ms installed.
These modern six-cylinder engines each produce 750 HP at 1800 RPM with a continuous-duty rating.
The boat also got new gears with a pair of Reintjes WAF374 having 6.417:1 reduction. The same four-blade stainless steel Rice propellers were maintained.
The vessel was built at Rayco Shipbuilders in 1980 and is one of Dann Marine’s 18-tug fleet.
She is 65 feet overall with a 24-foot beam and an 8.9-foot draft. She carries 16,000 gallon fuel and 5,000 gallons of water.
The tug can operate in push-mode with a pair of 20-ton Nabrico deck winches, each loaded with 110 feet of one-inch cable.
She can also tow and has a Markey TTC-18 towing winch fitted with 1000 feet of one-inch cable.
