Re: Water pooling on mooring cover
We use three poles to support the canvas.
Plus, at the stern - we installed two bow sockets and went to the hardware store and bought a piece of aluminum to use and cut it so it bows upward and supports that part of the canvas that's over the doghouse. it pulls the cover tight and we no longer have the pooling.
It works great - iboats carries them and the aluminum is inexpensive, doesn't rot and is easy to store. I would get the metal support brackets. Ours are screwed right into the side of the blower vents. four screws and you're done.
I'd hate to have to have all of those poles around.
