    Hi,

    I’m Looking for some fiberglass help. The picture is of the bottom of my swim platform. The area all cracked up is where the support brace connects to the underside of the platform. Any recommendations on the best method to fix this area? My current thought is to grind flat back the bottom and then build this area back up. However, I’m not 100% sure what materials to use here.

    Willing to learn a lot on this project, and have already done tons of research, just looking for specific guidance on this part.

    Thanks in advance!

    Seems like you’re on the right track, grind into it to investigate, keep taking pics, and post again.
    It’s obviously poorly constructed, but let’s look inside before jumping to conclusions.

    Thanks for the encouragement. Will be a couple of days before I can get grinding, but will post updates as we go!

    Pictures, pictures, pictures.
    Measures, measure, measure
    Then copy the numbers on to the pictures.

    You won't remember all the details when reconstructing

    You did already remove the platform so you can work on it on a bench.

    Probably only needs new pads. But might have hidden issues.

    What do you mean new pads?

    Is this a Crownline 206? As said previously, post a few more photos and let us know the make and model. A photo that shows the whole transom area would be helpful.

    The broken rectangle which presumably spread the load borne by the strut which fastened into those empty screw holes.

    How did this happen?

    I assume there was a stud embedded in the damaged area (?)

    Any other areas of damage/deterioration?

    Inworked for Crownline for a few years. It looks like rot. Some how water got into it and made the wood rotten. That's a heck of a crack. So did it get hit with something? I'd grind it all out replace.the wood in there glass it all back in from the backside. Covering the front of the he with tape or what ever donthe resin doesnt flow in. Then its basic gelcoat after that from the front. Altho I might also glass in metal as a brace behind that bolt hole.

    I believe he was talking about the rubber washers on the bolts.
