    Im in the process of assessing a section of the forward sole where water has rotted the area surrounding the live well hatch.

    The panels are screwed down from the top and sealed. Which at first glance appears to be a good thing in terms of repairing the core since I don't have to worry about finishing work to the top skin.

    I have searched and searched the web and cannot seem to find an example of this type of decking and it's removal.

    Anyone here that's repaired this type of decking?

    I'm curious as to how easy this will panel come out. Here's some pics attached. It appears it's only attached around the perimeter and has a horizontal frame glassed into the underside of the panel.

    Any insight would be greatly appreciated!!

    Welcome to the forum.

    Removable panels (what it looks like you have) are the easiest to repair, as you simply pull them up, makes the repair and put them back down. Since you have a patterned texture, you should consider trying to preserve this is much as practical. This often means peeling the upper skin away from the core, which can prove challenging if well stuck in some locations (you can bet it is). There are countless examples of this type of work, on this site in previous threads, which you may want to breeze through. Make a resin choice for the repair and move onto the details, as you come across them.

    Are they sealed or bedded Paul? I was debating doing this with the panels over my fuel tanks, but can't allow ingress.

    Thanks for the reply!

    So are you saying to try and JUST remove the top skin instead of the whole piece? Or, remove the whole piece and then separate the top skin from core?

    My plan was remove the whole thing and cut the bottom skin approximately 40x40 section, replace the wood and frame, then glass it back together.

    Typically you'd remove the piece if it's removable. Dan has a point, is it bedded or bonded? If it has screws around the perimeter, I'd assume it's bedded, which may be well stuck, given the age of the boat. Pry it up, the worst that will happen is more delamination, which you already have to deal with.

    Thanks! Gonna try to remove it this week.

    Not sure bedded vs bonded... nor do I really know the difference!

    Will post updates when I get there.

    Bedding is an sealant with possibly some adhesive qualities, while bonding simply means it's glued down. It wouldn't make a lot of sense to have a hatch, with perimeter fasteners that was bonded down, so I'm betting on bedding.

    It was definitely bedded. It came out pretty easily actually. That is, after 2hrs of cutting away the caulk. I made a hoist rig with a couple 2x4's and a come along and stuck a 3ft piece into the live well underneath so I could rachet it up and lift it up somewhat vertical
