I have a boat I leave in the water year round. But it’s called a Carver and it has a little thing called bottom paint.
Don’t leave your performance boat in the water. Buy the lift.

airdock doesn't raise the boat that high out of the water to block your view but will give it the protection it needs. Then just roll it up and store it in the shed for the winter or i think you can even leave it inflated for the winter and the ice will form underneath it. I power washed mine and put it away.
