A guy that owns a boat that is in a slip next to mine, has been sailing for over 15 years and has never been able to "park" his boat!!!
It helps that he is a really nice guy and an excellent sailor (except for mooring), and because of that, when he comes in or leaves, we all rush to help him in and/or out.
He hits all the boats and fingers from his slip all the way to the marina exit. We nickname him "Pinball Manoel", and he knows about it!!
Because of his "handicap", Pinball Manoel, aware of his inabilities, "surrounds" his boat with fenders!!! He has 6 fenders on the side of his finger, and 3 large ball shaped fenders on port, where is neighbour is. because sometimes we aren't there.
He placed 2 dock bumpers where is bow hits, and 2 on the side.
This of course should only be the last resource. He still hits everyone in and out, but the fenders somehow provide gracious help.
He points his boat (sometimes we wonder at what), and slowly lets it come to a stop. He then jumps out and has pre-made lines that he just fits over the cleats.
We still rush to help him, when he comes in/out, but only to help. We no longer fear for our boats.
