The 38'x13' monohull dive compliance vessel Sentry was recently delivered to the Washington State Department of Natural Resources (DNR) after successful launch and sea trials in Port Angeles Harbor. Last year, DNR selected Armstrong Marine’s proposal to design and build multiple vessels for its Marine Law Enforcement program.
Sentry is customized for efficient geoduck fishery management along with other marine law enforcement operations. A 4' dive platform, tank racks, aft deck shower, and custom dive ladder serve DNR divers monitoring geoduck stock and habitat.
“As the manager of 2.6 million acres of aquatic lands, the Department of Natural Resources plays a critical role in protecting our waters and preserving habitat from those who seek to damage it,” commissioner of Public Lands Hilary Franz said in a statement announcing the delivery. “The Sentry will be DNR’s first line of defense against derelict vessels, abandoned fishing gear, and plastics that pollute our waters. Built by Armstrong Marine USA right here in Washington, the boat and its crew will assist recreational boaters and enforce the laws that keep our natural resources healthy and productive.”
The aggressive lines of Armstrong Marine’s design lend presence well-suited for compliance missions. Armstrong partnered with DNR’s graphic designer to complement the boat’s look with vinyl graphics fitting of an official agency enforcement vessel.
Twin Cummins QSB6.7 425-hp engines in a semi-tunnel straight shaft arrangement achieve 24 knot cruise and 30 knot pursuit speeds. SeaStar/Teleflex steering with Capilano helm pump, an Imtra Side-Power bowthruster, Bennett electric trim tabs, and Garmin navigation package with autopilot complete the system, ensuring superior maneuverability around other boats. Two 180-gals. fuel tanks allow for long hours on station, while an offset windlass eases repeated anchoring. Sentry is also outfitted with two tow bollards, 3" D-rubber fendering, and Rigid LED flood lights.
Inside the heated walk-around cabin, six Bentley’s Mariner seats with heavy duty suspension bases accommodate captain and crew. Two folding tables and a storage cabinet lend versatility to the interior workspace. AJR Marine overhead spotter windows maximize visibility. A sliding half door at the helm offers quick operator access during mooring. The pass-through cuddy provides bow access and emergency egress in addition to housing the head and ample equipment storage shelving.
“We’re so proud to partner with DNR on this project,” Armstrong Marine USA managing director, Perry Knudson, said. “It represents what we do best — providing solutions to unique vessel demands to give our clients the best possible opportunity to succeed on the water. Sentry hits all the targets set for performance, use, and serviceability. These boats will be a striking presence in and around Puget Sound for years to come.”
Sentry was the first unit delivered under this contract; the second vessel, currently in production, will be completed later this summer.
