Hi we are nearing the final stages of our purchase of a Carver 404 and the survey has come back indicating several areas on the forward and side decks that did not pass the percussion test. The decks are stiff and show no signs of softness and I am wondering how serious these indications are?

The owner said that he has recently resealed the windlass and also where the base of the rails attach to the deck to prevent any further intrusion of moisture.

I have read that finding moisture in the core on a deck isn't uncommon with an older boat.

It doesn't appear to be serious and there are no signs of moisture coming through the deck into the cabin. Al of the material lining the roof and sides inside show no staining whatsoever.

I have seen videos of replacing damaged core from inside the vessel and I am really not too interested in taking on this type of repair as it looks difficult and expensive to do correctly.

So does anyone have any experience with moisture found in their vessel? I am thinking it is probably something owners do not openly discuss or are unaware that their vessel may have taken on moisture through one of the various attachments to the fibreglass.

Any thoughts on whether this is a deal breaker would be appreciated.
