Water is collecting under the settes and when I heel over water runs across the cabin sole. Where is it coming from? There are only few thru hulls on this boat and as far as I can tell they are secure. Could it be coming from the rudder post? I pump it dry at the slip and don't take on any more unless I am heeled over. The thru hull transducers are under the bow and are not leaking. It's a mystery to me!
