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 1 2 3 4 First at the top - Fenders can be strung together by passing the lan- yard of one fender through the eye on the bottom end of another.
