Just thought I would post this for anyone who hasn't considered doing this as part of their off-season maintenance. I noticed a part of rub rail sticking outward so I pulled the rub rail insert out to find a screw a 1/2" out. Seeing this, I decided to pull off the rub rail from the back all the way around to the other side. I kept one side in the cover cap. It took about a half hour to tighten all the cap screws and reinsert the rub rail. The constant pounding of your boat on waves and wakes will loosen these over time. Hope this helps. It's now part of my annual check list.
