SWELL WakesurfBig Bumper Ball 25 Inch Diameter - Inflatable Raft Tie-Up Boat Fender Buoy

I am not using this for it’s usual purpose. I’m using it as an above ground pool cover support. I grew tired of buying the vinyl cover pillows that usually deflated sometime during the winter.This is working great and if it survives the winter I’m getting two more to use together to create a large cover support next winter.

This is exactly what we needed to ensure our boat didn't bump into the dock overnight. :)

Not sure how long these have been available for purchase; however, now that they are available I encourage anyone with a boat to buy one for each side. You will never worry about tying up to a boat again. I put mine to the test at wakefest this year, and not one single scratch nor did I ever feel like they were going to fail. Please buy if you have a boat!

We have this at our marina slip. Its a great bumper to avoid hitting the dock. It's a good size... We have a 32ft center console. Gets the job done! Inflates well. Holds air well. We've had no issues so far.

I inflated these to 24 inches and then hung them up in the morning. A couple hours later they looked deformed and were deflating. Not sure if it was the heat and the contrasting temperature from being inside prior to inflation so I refilled them and they are still deformed and appear to deflate down to the size in the photos. At the time of the pictures (hours after placing them on a calm day so the boat never even bumped them) I had already refilled several times. I thought since it was a thicker material it would have held up but my neighbors who have a larger boat and bought a cheaper brand with thinner material is holding up.
