Four lines, four jobs
Most boats lie to a bow line, a stern line and two springs. The plan gives each one its own colour, its own length and its own job, so nothing is a guess when the wind comes up.
Read the guide and its sourcesBow line
Holds the bow to the dock ahead.
Stern line
Holds the stern to the dock behind.
Forward spring
Runs aft from forward: stops the boat surging ahead.
Aft spring
Runs forward from aft: stops the boat sliding back.
Fixed docks
When the water moves and the dock does not
A line tied tight to a fixed dock at one water level can hang the boat at another. The Water Level Check shows how much length a line needs across the range you expect, and how long a run keeps it within the give you accept.
Run the Water Level Check“In an extreme case, water levels between Toledo and Buffalo can differ by more than 10 feet.”
