Ideas of preventing the boat from sinking

[Bonmotwang]

I used to park my boat in my garage, so it is not an issue.
Now I started leaving my boat at my cottage. I have left it sitting in the water for maximum of 2 weeks. No issues, water seeping through the carbon seal is slow enough before I reuse it next time.
I do have a EZ Port for my jetski, but not the boat.
Just always worried that the boat may sink one day.
I have a lot of old blue barrels used in my old dock as float.
I am thinking about to build something with the floats to prevent it from sinking.
Not sure if anyone has thought of or done it with the similar ideas.

Why not replace the carbon ring?

I thought the carbon ring will always take in some water. In my case very very slow. Just wanted to be sure.

A couple good high flow bilge pumps with a solar panel trickle charger on the battery to keep it topped up. Oh. And fix the leaks

My dock is kind of U shape. So after checking the dimensions, I think the better and simpler way is to tie the front and back of boat to the dock. I can also put a webcam there so that I am able to check it every couple of days.
