I purchased the buoy to work with mooring pendents on a large mooring ball. It works fine. The mast makes the pendents easy to grab. I probably should have purchased a taller mast version for even more convenience.
A mast buoy takes away a lot of the drama of retrieving a mooring pendant. Forget the boat hook- you won't need it. The mast buoy makes it much easier when singlehanding. Get one- you'll love it.
