If you are mooring for a short time, bow and stern lines may be the only lines you
need. If you are mooring for a longer time, the currents are swift, or the weather
looks bad, 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 in a slip, bow and stern lines, port and starboard, will keep the
boat in position.
Note
: Manila rope, the standard for many years, is not as strong as some ropes made of
synthetic materials. For mooring, its ability to stretch is an advantage, but it tends to
shrink whenever it gets wet. nylon rope is strong and elastic. Because of its elasticity,
it works well for mooring lines and anchor lines. rope made of high tensile strength
polyester fibers like Dacron™ is just about as strong as nylon rope, but it does not
stretch. Kevlar rope is strong and does not stretch, but it is quite expensive.
Polypropolene rope tends to deteriorate rapidly when it is exposed to sunlight. Because
it floats, it is well-suited for use as a tow rope for water skiing. Use for other nautical
purposes is not recommended.
NAVIGATION LIGHTS
Cruising at night can be very pleasurable, but it can also be dangerous. Be especial-
ly careful of shallow waters and watch for submerged debris, rocks, and other
obstacles in the water. navigation lights are intended only to prevent collision, not
to improve night vision. you may choose to use a spotlight, which is available from
your dealer or local marine store, to aid in night navigation.
