During the winter months you should never leave your pontoon boat in the water. If you do, you’re leaving it at risk to the elements and can get hit with some expensive maintenance bills.

Ice can damage your pontoons, algae and scum will build up, and overall, you’re going come back at the start of the season to a boat that will need a lot repair. You must winterize your pontoon boat (here’s how), and get it out of the water as soon as you can.

But what if you don’t have a trailer? How can you store a pontoon boat without a trailer so it’s safe, secure, and free from getting damaged?

Can you leave a pontoon boat sat on the ground?

Firstly though, you don’t want to simply leave your pontoon boat grounded and on dry land. Both pontoon tubes should be level when stored. If they aren’t you could damage the pontoons if left on uneven ground. I’ve heard of decks becoming twisted and warped when this has not been done properly.

The aluminum tubes should also not be put at risk of exposure to any potential hazards that could puncture the aluminum.

A grounded pontoon boat is also going to be a magnet for critters wanting to nest for the winter; it needs to be raised off the floor at all times.
