UNDERWAY
The mooring lines you will use most often are the bow line,
the stern line, and spring lines (Figure 5-5). Each line has a
specific purpose. The bow line and the stern line secure
your boat’s bow and stern. The two spring lines keep your
boat from moving forward or backward when you are
moored alongside a dock. Attach mooring lines only to
deck cleats or side rail mooring eyes. Do not attach lines to
any other part of your boat.
If you are mooring your boat for a short time, bow and
stern lines may be the only lines you will need. If you are
mooring your boat for a longer time or the currents are
swift, you should use spring lines. The stern spring line
leads from the boat’s stern cleat forward to the piling or
cleat on the dock. The bow spring line leads from the bow
cleat aft to the dock.
If you are mooring your boat in a slip, bow and spring lines,
port and starboard, will keep your boat in position.
NOTE: Moor the boat so that the motor intake vents are
leeward. Otherwise, water can be forced into the vents and
cause damage to the engine.
NOTE: If tides are a consideration, be sure to leave slack
in the lines to make up for the rise and fall of the water
while your boat is docked.
EMERGENCY OPERATION
Boaters should respond to emergency calls if they are
nearby and can help. You are expected to proceed to the
scene and render assistance. Distress calls often are
made for assistance with a disabled boat. A VHF marine
radio (channel 16) is the best device for calling for help.
Two international emergency signals are MAYDAY
(life/death situation, request immediate assistance) and
PAN PAN (safety of the boat or person in jeopardy).
The Federal Boat Safety Act of 1971 requires boat
operators involved in accidents to offer aid to others in the
