In stronger winds most boats will yaw more than 90 degrees, some as much as 130 degrees if the wind is gusting down adjacent valleys. One solution to this is to lay a second anchor in a technique known as ‘fork mooring’. The second anchor is laid at about 90 degrees to the bower, with the same scope. This is more easily done from the dinghy but is possible by moving the yacht, although estimating just where to drop the kedge is not easy. The boat’s yaw angle is considerably reduced by this measure.
