We live on a canal about 3 houses from the open bay. Depending on the wind, the boat can really pound the poles. I have big whips, but they do not do the job in rough weather. I have seen "mooring arms" for sale that hold the boat a constant foot off the dock. They are just not in the budget. I have also seen "homemade arms" that appear to be 4"galvanized pipe mounted on some sort of hinge. The pipe sticks out into the canal about a foot behind the boat and another about a foot in front. The lines go from the pipe to the boat and hold the boat off. I have a general idea of how to make it. I was just wondering if anyone has done this or seen it. Looking for any advice.
