Chapter 2 – Boat Characteristics
Section B. Compartments
Introduction
The hull of Defender Class boats (Figure 2-2, Figure 2-3, and Figure 2-4) is
comprised of a single pressure-tested, airtight, welded compartment. A fuel
tank (125 gallons, RB-HS and 105 gallons, RB-S), fabricated from ¼-inch
5086 aluminum and supported by rubber isolation mounts, is part of the
hull’s structure.
B.1. Anchor/
Ammunition
Locker
An anchor locker, with fabricated door (Figure 2-5), anchor tie-downs, and
drain, is located at the bow, forward of the bitt. The locker has drain holes
that empty onto the foredeck and out through the shell discharge tubes.
Storage shelves are built into the locker door to accommodate four boxes of
ammunition.
B.2. Cabin
The full width cabin (Figure 2-6) has seating for four crew with additional
seating in the cuddy cabin. The RB-HS has two pneumatic suspension seats
forward and two bolster seats aft. The RB-S has four pneumatic suspension
seats installed. Port and starboard sliding glass windows allow for air
circulation and overhead tinted spotter windows allow for greater visibility.
A hinged weather-tight door is built into the aft bulkhead. Two sliding doors
are located on the port and starboard sides of the main cabin. Welded
handrails provide a minimum of two handholds for every seated
crewmember. An overhead hinged instrument panel (OHIP) holds secondary
“Contura” switches for navigation and deck lighting. Two 12-volt fans are
mounted on the OHIP.
