fall freely with the tide, and this can vary substantial-
ly from place to place. The tidal range can be very
wide; for example in UK spring tides can reach up
to 4m in the Solent, or even 12m in the Bristol Chan-
nel. The final mooring arrangement must allow for
the vertical movement of the boat as she rises and
falls with the tide. However while the boat must be
free to move vertically, you also need her to stay in
place alongside the wall so that the crew can use the
ladder at any tidal level.
Here are the golden rules:
(Picture n°1 - down below)
•
Use at least 4 separate mooring lines
•
If windy remember the boat is not berthed safely
until all the mooring lines are in place
•
The length of each warp must not be less than ¾
that of the entire tidal range
•
1 - Bow line runs from the bow to the wall
ahead of the yacht, and will prevent the bow from
swinging away from the wall
•
2 - Bow spring runs from the bow back along
the wall, and will stop the boat from surging forward
•
3 - Stern spring runs from the stern forward
to the wall, and will stop the boat from surging
backwards
•
4 - Stern line runs from the stern back along
the wall and will prevent the stern from swinging
away from the wall
Firstly, you must check that there will be sufficient
depth at low water. In order to do this you need to
calculate the tidal range, determining how far it will
