Handy Duck boathook
This is by far the best constructed of all the variations of this type of equipment. It clips easily onto buoys with an upstanding ring, cleats and rails, It is strong enough to leave as the main mooring line (all the others are temporary and need to be replaced with a proper mooring line). Undoing the clip is easy and positive. So this can be done from on board. For peace of mind, there is small peg which can be inserted to prevent risk of the clip coming undone accidentally. The price is approx half the new price.
In excellent condition.
