I have noticed a large bubble measuring perhaps 1' x 1' on our port Naiad stabilizer fin. Curious if others have ran into this issue. It likely has been there for some time.
Any ideas on what this should cost to repair? I already have new seals, bearing retainer and bolts etc. so the fin will be removed anyway.

Re: Stabilizer fin bubble repair?
Did you check it with a moisture meter? Having one of mine dried out and epoxied over the winter from moisture inside of it. No bubble on mine though.

Re: Stabilizer fin bubble repair?
It is a very simple repair and a somewhat common problem. I've had three of them fixed.
The fin is constructed of a stainless shaft that you can see and within the fin there are at least two flat stainless cross bars. This is the framework. This is embedded in foam of the appropriate shape and that is glassed over. The repair was to grind out the bubble and repair with glass/epoxy, fair and repaint.

Local fiberglass guy says 1000+ to fix this and that is with me bringing it to him? Does that seem absurd?

Are you in California?
If its a small bubble that has not gone through the skin its no big deal. Is there more to repair than just 1 blister?
If you have it stripped to bare fiberglass, Repair the blister, recoat with 6 or 8 coats of barrier coat and then repain and bring back to the boat maybe.Scott

Re: Stabilizer fin bubble repair?
I though it was inches not feet. I don't know. Without seeing it I can't determine the extent of the examination if that's even what it is.
For a professional to spend 8 to 12 hours plus materials it's probably not bad for $1k.
Remember it needs to have all the barrier coat and paint put on after the glass and epoxy. It adds up.Scott
