The 38 x 13-ft. monohull dive compliance vessel Sentry was recently accepted by the Washington State Department of Natural Resources (DNR) after successful launch and sea trials in Port Angeles Harbor. In a competitive solicitation process last year, DNR selected Armstrong Marine’s proposal to design and build multiple vessels for their Marine Law Enforcement program.

Sentry is customized for efficient geoduck fishery management along with other marine law enforcement operations. A 4-ft. dive platform, tank racks, aft deck shower, and custom dive ladder serve DNR divers monitoring geoduck stock and habitat.

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-gallon fuel tanks allow for long hours on station, while an offset windlass eases repeated anchoring. Sentry is also outfitted with two tow bollards, 3-inch 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.

Sentry was the first unit delivered under this contract; the second vessel, currently in production, will be completed later this summer.
