Boat Handling

Anchoring

1.) Shank – Aids in setting & weighing the anchor. Attachment point for the anchor for the anchor line

2.) Flukes – Dig in the bottom & bury the anchor, providing holding power

3.) Crown – Lifts the rear of the flukes, & forces the flukes into the bottom

4.) Stock – Prevents the anchor from rolling or rotating

Scope of Line

  • Ratio range between 5:1 & 7:1
  • (Example: for the 5:1 ratio, anchoring in 20ft of the rope should be 100ft)

Anchor Description

  • Fair - Clean
  • Fouled – Hung up / Caught on bottom
  • Shawed - Muddy/ Dirty

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 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).

MEMORY AID

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 132°.

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 (DR)

Dead reckoning is the determination of approximate position by advancing aprevious position for course and distance only, without regard to otherfactors, such as, wind, sea conditions and current.

Dewatering Pump (USCG-P6)

Description

  • 6 ½hp 4 cycle engine
  • 3inch suction and discharge hoses
  • Priming at 12ft in less than a minute
  • 250 gpm
  • 4 gallon fuel tank

Damage Control

  • 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.

FIRE

  • 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.

Loss of Steering

  • Check space behind steering console.

  • Check for kinks in hoses near outboards
  • Contact Station

Collision with a Submerged Object

  • Check all spaces starting from the Bow and working your way aft.
  • Check for sheen on water.
