Paint or not paint

I keep my V20 in the water all season on Lk. Michigan. It's my first season keeping it in the water. The bottom is not painted so it quickly gets covered with gunk and algae. Performance goes to hell when the bottom is not clean. I've taken it out twice and powerwashed it and cleaned it with muriatic acid. It works but is a pain in the ***.

Thinking in the spring of putting a primer and Awlgrip Allstar bottom paint. Supposed to last 5 years.
