All void tanks have high level alarms with bilge piping.
A 110-gallon lube oil tank and a 110-gallon transmission oil tank are built into the hull.

Standard equipment includes navigation lights, one incandescent and one Xenon searchlight, 40-ton Wintech electric winches, Schuyler rubber towknees, perimeter fenders, shore power plug-in, and Fernstrum zero-knot coolers.
The superstructure is constructed of 3/16-inch plate with 2- by 2-1/2- by ¼-inch framing; main deck doors are watertight, and windows are aluminum with safety glass panes. Spartan quarters are insulated, paneled, heated and air conditioned and have poured rubber flooring.
The first deck contains a 12- by 10-foot, a modest head with shower and a U.S. Coast Guard-approved marine toilet. The second deck has storage space. The pilothouse has full instrumentation and vessel control. There is a 3-foot space below the pilothouse to make an eye level of 28 feet.
