Steering Nozzles – The steering nozzles are controlled by the Vector Control System and powered by hydraulics. They have
a max range of 30 degrees port and starboard.
Reversing Buckets – The reversing buckets are also controlled by the Vector Control System and powered by hydraulics.
The impellers turn the same way regardless of the boats forward or backwards movement. The buckets are what deflect the
forced water in the opposite direction, causing the boat be thrust backwards.
Backflush – reverses the actual direction of the shaft/impeller (used for clearing lodged debris out of the inlet ducts) Do
not exceed 1200RPM’s when backflushing.

AURAGEN Viper G8500X Induction Power Source (IPS)
 2 total- one on each engine
 Belt Driven from the engine
 Creates 120/240VAC
 8.5kW
 60Hz
The generators create the 120/240VAC then send it to the ECU/ICS in the AMC space. The ECU/ICS converts the
120/240VAC into 24VDC which is then sent to the battery chargers. Though it may sound strange, the ECU/ICS then inverts
24VDC back into 120VAC which is then sent to the VAC panel under the chart table.

(Ref. - 45 RB-M Operators Manual/IETM, Chapter 3.J.3) (Ref. – RB-M Operators Handbook, pg. 244-249)





There are two self-contained 16,000 BTU A/C Units on the RB-M located in the Pilothouse and Survivors' Compartment.
Both A/C units are cooled by raw water provided by a 12GPM centrifugal pump located in the engine room just below the
ladder.
Control panels (thermostats) are located on the engineer console above the breaker panel and the other is in the survivor
compartment above the sink.
Pilot house unit condensate line gravitationally drains overboard on the port side at frame 7.
Survivor compartment condensate pan drain line drains to a self contained 12.5 GPM condensate sump pump located in
the survivor compartment bilge between frames 10-11. The sump pump is automatically activated by a float switch when
condensate reaches a level of approximately 3”. The reason for this is because the survivor compartment HVAC unit is
positioned at/below the water line therefore gravitational drainage cannot occur. So it drains to the sump pump and then is
mechanically pumped up and out above the water line. The condensate line drains overboard on the starboard side at frame
13.

SELF RIGHTING CAPABILITIES
(Ref. RB-M Operators Manual/IETM, Chapter 7.A.1) (Ref . RB-M Operators Handbook, pg. 72, 405)





The self righting feature will work more efficiently if all watertight hatches and windows are properly secured.
The boat has a positive righting arm of 0-180 degrees (meaning the boat re-rights its self regardless of how far it heels
over).
This self right capability is accredited to the boat being designed with Buoyancy Chambers and a Counterweight design.
Boat re-rights itself in 8-12 SECONDS.
The boat is equipped with a “Roll Over Switch” that is located in the AMS on WTB 7. When the boat rolls 90 degrees (per
IETM) 90-100deg (per Operator Handbook) or more the Roll Over Switch activates, reducing the engine RPM down to
idle to prevent engine damage and minimize the amount of water that enters the engine room. To regain throttle control or
“re-qualify throttles” the coxswain must momentarily bring the joystick back to zero thrust.
CAPSIZING PROCEDURES
(Ref. RB-M Operators Manual/IETM, Chapter 7.A.1) (Ref .- RB-M Operators Handbook, pg. 405-407)
In the event of a capsizing the boat should self right in 8-12 seconds. Once re-righted follow these steps:








Re-qualify throttles
Position boat in a way to be able to successfully take additional waves (preferably bow to the swell)
Account for personnel
Check for gear, lines, anything that might fowl the jets, etc. in the water around the boat
Move boat into safer waters
Crew and Engineer check all spaces for damage/flooding
Notify Station
Determine if it is safe to proceed with mission

OTHER INFO THAT YOU NEED TO KNOW…
How many LED deck lights are there? - 10. Two in each recess, one on each side of the pilot aft of the recesses, two on the laz silo
and two on the transom above the swim platform.
Where are they controlled from? - Engineer console, far left bright/dim toggle switch.
What else is controlled from that toggle switch bank? – Exterior deck lights, Interior lights and instrument dimmer / Window
heater/ Engineroom exhaust fans/Window defroster/ Bilge pumps
In addition to the 35 different Joystick/Helm/Waterjet alarms on the VECTOR ALARM PANEL what other five systems does
it monitor? – Heat Sensors, Smoke Sensors, CO Sensors, Bilge Sensors, and Low hydraulic pressure.
Where are the smoke alarms? Survivor compartment, Aux space, Pilothouse, Engine room
Where are the heat alarms? – Survivor compartment, Aux space, Pilothouse, Engine room (activates when the temp in the space
reaches 190deg.
Where are the CO alarms? – Pilothouse and Survivor’s compartment.
What is the primary compass on the boat? The electronic compass
Where is compass heading sensor located? – In the survivor’s compartment bilge underneath the tool box. Between frames 10-11.
How many heavy weather D rings are there on the boat? - 50
What is the rule when moving about the deck when using the heavy weather belt? – Always have one hand on the boat and
always have at least one of your HWX clips securely attached to a D-ring. When you’re not moving around and you are not working
the deck both clips should be securely attached to two SEPARATE D-rings.
What is the proper position placement for the heavy weather belt on a member? Thug style! Belt should be positioned snuggly
on your hips (NOT around your waist! Unless you want serious back problems)
How many thru hull fitting are on the sea chest? - Six
What do they go to? – Two sea suctions for the engine raw water system, one for the p-6 stand pipe, one for the A/C and two for the
deicing valves.
What is DDEC? – Detroit Diesel Electronically Controlled. (The electronic brains of the engine). The DDEC monitors the engine
systems/pressures and regulates fuel injection. In the event that something goes wrong in the powertrain, the DDEC will give a visual
and audible alarm through the EDM’s located on the engineer console and overhead console.
Why does the boat move around slightly in the same position instead of ahead or astern when the clutches are engaged? –
When the throttle joy stick is in the zero thrust position the reversing buckets are halfway down (also known as neutral bucket). This
means that half of the water being blown out the nozzles is being redirected forward. Therefore the boat will move around slightly due
to water being jetted fore and aft.
What is the maximum speed you can be operating at and be able to switch from TRANSIT to DOCKING? – 5kts
What position does the joystick have to be in to switch from DOCKING to TRANSIT? – Zero thrust
How do you shift control station? – Attempt to match the active station throttle then depress the ACTIVE button twice. The green
light should light up on your station. You then have a few seconds to actually meet or exceed the previous station’s RPM’s to gain
control.

CAUTION!!! This is just a study guide. Human error is possible. I tried to reference as much as I possibly could so you can quickly verify accuracy. You’ll probably end up learning more
about stuff not on this study guide if you do dig into the manual and verify.
What if you’re at the dock and take station but the clutch panel will not engage? – Check to make sure your throttle joystick is in
zero thrust position.
How do the Interceptors work? – The interceptors are much like adjustable trim tabs with the exception that when they are lowered
they create more significant drag than a typical adjustable trim tab. The interceptors automatically deploy when maneuvering the boat
to port or stbd. For instance… if you turn port, not only do the nozzles turn to port but also the port interceptor lowers creating drag
which ultimately turns the boat much more abruptly. You turn stbd, the stbd interceptor lowers and does the same thing.
Where is the pivot point on the boat? – Approximately at the aft cabin bulkhead
How long does it take for the reversing bucket to go from all the up to all the way down? - 3 seconds
What is being caught in a “Hard Chine”? - The boat suddenly heeling over 50-80 degrees on a false keel. The false keel is usually
one of the chines. The 45’RBM does not have chines and therefore will not catch a hard chine.
How do you correct a hard chine? – Reduce speed enough to come back to an even keel.
What is FLOCS? – Fast Lube Oil Changing System
What is the requirement for a crewmember to go aft to the swim platform? – To have to crew-comms on or have a spotter.
How many 12V batteries are in the AMC? – Four batteries total, two in each box.
How are they wired? – Wired in Series (remember Series increases volts whereas Parallel increases amps)
Which battery bank does what? – The START Bank (port box) is for starting the engines and controls the second 24V panel
“Engine Bus”. The HOUSE Bank (stbd box) powers the first 24V panel “Vital Bus” and third 24V panel “Non-Vital Bus.
Where does the 12V panel get is power from? – From the 24V Vital Bus through a 24V-12V converter.
What breakers should be left on while in port on the 24/12VDC panel? – 11 total. All four MAIN breakers for each panel. Both
12V CONVERTERS on the vital bus, then the ALARM PLC, BILGE SYSTEM, CREW COMMS, LOUDHAILER and LAW
ENFORCEMENT LIGHT. (Helpful Hint: 4 MAINS, 2 TWELVES and an ABCLL)
What breakers are left on while in port on the 120VAC panel? All three MAIN breakers, BATTERY CHARGER, OUTLETS,
MICROWAVE, and both BLOCK HEATERS. (Helpful Hint: 3 MAIN BOMBs)
Where is the Depth Sounder transducer located? – Between frames 1 and 2 to the port side of the keel.
What is the fendering system made of? – 6’ sections of D-shaped ionomer foam.
How do you lower the mast? – Rotate the locks. The mast is fitted with gas shocks so it will not fall down. Using a boat hook slowly
guide the mast down.
During U/W operations how should the recess grates be positioned? – One up, one down. Expect during HWX. Both should be up.
What is the weight capacity of the egress ladder in the Survivors Compartment? – 400lbs.
Where does it attach to? – The D rings on each side of the deck plates.
EPIRB – McMurdo Smartfind G5, 406MHz/121.5MHz, Category II-manually activated. Accurate to 30 meters, transmits for a
minimum of 48hrs.
