The water in the bilge is like leaking through the scuppers. I'm not sure if the 18 has thru-hull scuppers, but if so its a common problem and an easy fix.

What happens is the the scupper tubes separate from the glass-wrapped wood block that encases them and incoming water begins to rot through the wood block and trickles along the stringer falling into the bilge.

Any number of ways to fix it, but do a search for scupper repair over 3 years or so and you'll find a bunch of insight from many who've shared the experience.

Good Luck!
