Could be starting to break away inside or maybe salt is just building around a very small edge, maybe put some wax around it to seal it or cut some rail saver tape and stick it over both holes?

They are leaking. Water is getting into the blank.

You must act fast: time is of the essence: boardlady.com/watervseps.htm

You should at least drill holes around the plugs, and insert tissue fans to dry them. boardlady.com/waterextraction.htm
It can take days.

Then inject resin + microspheres (or foaming epoxy) to re-build a solid base

Then re-glass on top of the plugs.

its weird the board is not taking on water ,I am hoping and thinking Sunova put matting in each plug
then sand the top off ,so hoping the water is just in the fin plug cavity not the board .
I might send a email to them .The board didn't get heavier ,I will still get the resin to it ,

Do sunova use higher density foam blocks when inserting the fin plugs, perhaps this doesn't absorb water as the polystyrene blank does?

Hi Tardy,

I just came across this post, in future don't hesitate to reach out directly if you have any questions.

What you are seeing here is completely normal on SUNOVA boards fitted with FCS plugs. The FCS system is designed to be installed after the board is fully laminated meaning no fibreglass will be over the top of the plug. We install our plugs into high density PVC inserts, if we installed them straight into the lightweight foam core they would break out very easily once pressure was applied.

The material the plugs are made out of is Nylon which is notoriously difficult to bond or adhere too. Hence when you see the bottom of an FCS plus there are many cutouts or crevices for the resin to protrude. We use an epoxy blend mixed with milled fiber for the install. Because the plugs are seated in the PVC material, the core is completely protected from water intrusion so there is nothing to fear and no action that needs to be taken. Cheers,

Dylan

Hi Dylan,
I'm glad you chimed in on this thread as I was looking at buying a placid to compliment the SP25 I have. It's good you explained what the salt residue was and allayed any fears for all of us.
Cheers
Steve.

Well, interesting.

Although, if it was my board, I would be wary of letting salt water come close to wood... but it's not.

Just use futures and be done with it. You won't have to worry about your fins falling out of the terrible gen1 fcs plugs either. That being said I have broken the glass covering a futures box after a rock hit my board.

Hey Dylan,
So good to have the actual manufacturer giving the correct advice to educate us on the design features that go into your boards.
You just saved old mate time and money.

i never rinse my creek (or any of my boards) and its plugs often look same as yours -- at first i worried -- creek told me nbd, i was skeptical -- now, years later, same thing, and the board has never taken on water or gained weight -- board's been solid otherwise too and rides great-- sometimes i wish it would fail so id have an excuse to replace it!
i alternate it with my starby pro -- btwn these two, cant imagine a huge improvement -- love both of them -- starby a bit skinnier at 29", seems better with steep fast beachbreak round here outta brooklyn -- new england rocky points, prefer the creek

My sentiments exactly, you do have to be careful who you seek advice from.
