DOCK LINE BASICS
Most skippers use dock line
terminology fairly loose but there is
more to the basics than just bow or
stern lines. There are several lines
that can be secured to the bow and
stern and depending on their
direction and use, can be called other
names. Remember that “forward”
and “aft” refer to the direction that a spring line runs from
the vessel, and not where it is secured on board.
BOW & STERN LINES
There is only one true bow line. It is secured to the forward
cleat and run forward along the dock to prevent the vessel
from moving to the stern. The stern line leads from a rear
cleat to a piling or cleat on the dock astern of the vessel.
This line keeps the boat from moving ahead. For small
vessels these are the only lines needed for normal wind
and current conditions. If located in a tidal environment,
keep slack in the lines.
BREAST LINES
These lines are attached to the bow and stern that lead to
nearly right angles from the center of the vessel to the
dock. They help keep larger vessels from moving away
from the dock, or are pulled in to help people board the
vessel. Bigger vessels may use bow or quarter breast lines.
SPRING LINES
Select boats use two spring lines although it is possible
to have four. They are called the after bow spring, and
forward quarter spring cleats.
Bow springs are secured at the vessels’ bow area. Forward
spring lines lead forward from the boat to the dock and
control movement sternward. After springs stem aft from
the vessel, and stop movement ahead. Spring lines are used
to prevent movement in a berth, ahead or astern. They are
really useful in controlling the effects of a real active tidal
surge. Spring lines are useful where fenders need to be
kept in place against piles.

BOAT MOORING
Most boats can be secured to a dock using four lines. The
after bow spring is crossed with the forward quarter spring
and secured to individual dock cleats or pilings. This ensures
longer springs and can be snugged up tighter for more
efficient tidal control. Remember, if you only have one piling
available, position the vessel so this point is opposite
admidships. Run both spring lines to it. These lines will be
shorter but still useful.
