Crew Efficiency Factors and Team Coordination
Crewman Responsibilities
Crew members safely perform their duties under the supervision of a coxswain. They stand:
o Helm.
o Lookout
o Towing watches.
o Anchor watch.
They also:
o Rig towing and mooring lines.
o Act as the surface swimmer.
o Administer first aid.
o Operate damage control equipment.
This position provides valuable training for future duties and responsibilities

First Aid and Survival
Bleeding Control
Control of severe hemorrhage is always urgent. With only 10 pints of blood in the human body, arterial
bleeding can cause death in a short time.
Types of Bleeding
 Arterial
o Blood coming from an artery, bright red, gushes in jets with pulse
 Venous
o Blood coming from a vein, dark red, steady flow
 Capillary
o Blood coming from smaller vein, bright red, oozes from wound

Variation and Deviation
Variation - Magnetic variation is the difference between true bearings and magnetic bearings and is caused
by the different locations of the Geographic North Pole and the Magnetic North Pole plus any local
anomalies such as iron deposits. Variation is the same for all compasses in the same location and is usually
stated on good quality maps and charts, along with the date it was measured.
Deviation - Magnetic deviation is the difference between magnetic bearings and compass bearings.
Deviation varies for every compass in the same location and depends on such factors as the magnetic field
Station Port Aransas, Texas
Reserve Study Guide
of the boat, wristwatches, etc. The value will also vary depending on the orientation of the boat. Magnets
and/or iron masses can be used to correct for deviation so that a particular compass will accurately give
magnetic bearings. More commonly, however, a correction card will be drawn up listing errors for the
compass which can then be compensated for arithmetically.
Correcting & Uncorrecting for Compass Error
“Correcting” is going from magnetic direction (M) to true (T), or going from the compass direction (C) to
magnetic (M). To apply compass error to correct course or direction:
• Take the compass course.
• Apply deviation to obtain the magnetic course.
• Apply variation to obtain true course.
The sequence of the procedure is outlined below:
• Compass (C).
• Deviation (D).
• Magnetic (M).
• Variation (V).
• True (T).
Applying compass error:
Can Dead Men Vote Twice At Election
(Compass) (Deviation) (Magnetic) (Variation) (True) (Add) (Easterly error)
Add easterly errors - subtract westerly errors
For the compass course is 127°, variation from the compass rose is 4° W, and the deviation from the boat’s
deviation table is 5° E. Then, the true course (T) is obtained as follows:
Step Procedure
1.) Write down the correction formula:
• C = 127°
• D = 5° E
• M = 132°
• V = 4° W
• T = 128°
2.) Compute the information opposite the appropriate letter in the previous step.
3.) Add the easterly error of 5° E deviation to the compass course (127°) and obtain the magnetic course of
4.) Subtract the westerly error of 4° W variation from the magnetic course (132°).
5.) The true course is 128°.
Converting from true (T) direction to magnetic (M), or going from magnetic (M) to compass
(C) is “uncorrecting”. For converting from true course to compass course:
• Obtain the true course.
• Apply variation to obtain the magnetic course.
• Apply deviation to obtain the compass course.
Converting true course to compass course:

Dead reckoning is the determination of approximate position by advancing a previous position for course

Damage Control
Station Port Aransas, Texas
Reserve Study Guide
The RBS does not contain a damage control kit. However, most items can be used
to plug holes on a sinking boat if needed. Use various shocks and wedges and
makeshift items to stop the sea from coming into a space that would effect a
vessels stability.
Fire Fighting
 Fire fighting is not performed from the RBS unless a Certified Fire Officer is in
direction of the crew and permission has been given by the Chain of Command.
BECCE (Basic Engineering Casualty Control Exercise)
 All BECCE drills will result in a crewmen to rig and ready the anchor. This will
be the first sentence with most BECCE’s for any other crewman underway unless
otherwise specified.
 The other crewmen should grab the fire extinguisher from the cuddy cabin. This is
the primary extinguisher on the RBS for anything on the aft of the boat.
 Attempt to extinguish the flames by putting the extinguisher through the air intake
vents on the cowling
 If the extinguisher is depleted, use the second extinguisher if accessible in the
starboard deck locker.
 If the fire is still out of control, the coxswain may back down hard on the other
engine to wash water over the aft end.
