10-2.5 Special components mounted on workboat
Reel, aluminum, w/mount*
Line, messenger, 3000 ft, 5/8 In kevlar, 8000 lb test pull*
Reel w/mount is attached to a sliding base that is bolted on rear workboat deck over engine compartment and
holds messenger line. Sliding base is on outside of engine compartment and allows reel to be moved forward
against workboat cabin for easier access to engine compartment. It can be moved to the rear to allow use of aft
door from cabin and for dispensing messenger line from shore to barge. Reel and mount are locally fabricated.
Messenger line, in conjunction with AMCON shore winch pulls shore discharge hose from barge to shore.
10-2.6 Equipment specifications, maintenance information, and manufacturer's service manuals are contained in
10-3 Capabilities. This boat has a rated load capacity of 4000 pounds, or six passengers, operator and 2600 pounds.
The messenger reel and line, when mounted, weigh 670 pounds, and workboat's load capacity must be reduced by this
amount. A full fuel tank of 50 gallons of diesel fuel provides about 3 hours of operations. Depending on the propeller
fitted, speed, load, sea conditions and amount of maneuvering, this fuel should provide a one-way range of about 70
10-4 Special limitations. Although the aluminum hull is reinforced, it is neither designed nor constructed to be run
ashore. When running in shallow water, the outboard drive should be raised to full "beach" position to reduce possibility
of damage to the outboard drive. In this position, the outboard drive produces less thrust.
10-5 Performance characteristics. According to factory tests, with only operator onboard and using a 3-bladed, 16-inch
propeller with 21 inch pitch, boat has a top speed of 30 mph at a maximum attainable rpm of 3150. Boats are now
equipped with 3-bladed, 16-inch propellers with 19-inch pitch, and factory performance data is not available for this
combination. These boats, at full rpm, have a turning radius of about 90 feet.
Section II. Operating instructions
10-6 Controls and Indicators. Operator controls and indicators are at operator's station in workboat cabin on forward
starboard side (Figure 10-3). Workboats have same controls and indicators, but the locations of dash-mounted items vary
among different boats. Following sections provide general location and operating instructions for controls and indicators
in the workboat cabin.
10-6.1 Searchlight. Searchlight controls protrude from cabin ceiling above and forward of wheel.
Direct light by rotating handle around vertical shaft. Light is directly attached to shaft.
Raise lightbeam by pulling down on handle.
Lower lightbeam by pushing up on handle.
Switch is on operator's electrical control panel.
10-6.2 Operator's electrical control panel. Mounted on the dash, this panel has ON/OFF switches for searchlight,
windshield wipers, cabin dome light, engine room light, and running lights. Switches are on left side of panel, labels are in
the middle, and fuse containers are on right side.
10-6.3 Windshield wiper. Windshield wiper motor is mounted above windshield, and ON/OFF switch is located on the
electrical control panel.
10-6.4 Boat horn. Horn is mounted on top of cabin, and horn button is located on the operator's dashboard. Push to
