The pinless moisture meters can be pricey ($~250). Check with a local surveyor, they usually have meters. See if they'll inspect just the rudder. I wouldn't drill holes before I was absolutely sure there was water in there.
There were little or no indications of water in mine but when the fiberglass guy removed one side of the fiberglass shell, he was able to pour water out. The foam was completely saturated which prevented any outward sloshing sound.
