Why would I be taking on water?

Hooper,
On a pure statistical guess, I would say it is from the splah well hatch cover. Most SeaCrafts leak there after a short period of time. Take a tube of cheap silicone, and seal it completly. After that, if you are still getting water, try turning all the seacocks off, and see if that stops it. Anotherr option is that rain/splash water from the top deck is coming in around one of the hatches. The last possibility is that it is leaking around a thru-hull water intake, or a transducer???.

Just a thought,
If your boat has the thru hull brass sleeves in the cockpit sole or forward well they might be loose and leaking. Easy enough to fix with new sleeves but hard to detect because its almost impossible to see if they are leaking between the bottom of the boat into the inner part of the hull. IF they are origional I'd knock them out and replace. Some elimate them totally and glass over the holes, its your preference.

Don't know how practical this is but one way we used to test for water leaks on cars is to spay a very foamy glass cleaner around any potential leak and subject it to compressed air from the other side. Any aire coming out would disrupt the foam... Obviously the boat would need to be out of the water for many checks...

If you have a drain fitting for the bow compartment right at the waterline, that fitting can leak. It is a bronze threaded tube (thru-hull) that is snugged up against the inner liner of the bow compartment/fish box, and then the outer mushroom is tight against the hull at waterline. If that is not secured really well (5200, etc), the working of the hull (and yes, in a sea there will be some flexing) may cause a gap to build in over the years that you don't see when the boat is at rest. In part, this is made worse because the inner liner and hull will flex at different rates due to thickness - and that fact that outer hull is being slapped directly. So -- when replacing -- snug well, but not too tight to overstrain the inner liner. And seal well with 5200. My 18' had a leak and took me a while to track it down also.
