Fiberglass Dots on Hull

[Papabrer]

Hi All,

Have noticed some anomalies on my boat’s fiberglass. I haven’t noticed them previously. Per the attached picture, they are round dots that a visible and protudes from the starboard side of my deck. There are maybe 4-6 dots, all the same size/shape.

Any ideas or suggestions would be appreciated

looks like some kind of blister or delamination. Push on them -- are they solid or a bit of flex. My guess is you'll need to open them up and fix.

Is that area previously repaired? Agree with Golfman...looks like a blister, but unusual place (usually underwater).

But regardless those would be easily repaired and not a lot of $$$.

Agree with the others, however if you magnify the first pic you can clearly see the deck hardware/screws are loose, no evidence of caulk, and there are multiple cracks above the anomalies/blisters where moisture could have entered over time.

Thanks everyone, yes they do flex a bit. I will get them repaired. I will also check the deck hardware, I hadn’t noticed that.
