After a strong rain, I notice a good bit of water finding its way into my Ericson 29. The water gathers on the cabin sole and seems to be in the cub bard to the right of alcohol stove. NO water in the drawers, no water in the cubbard under the sink. no water in the cubbards behind the stove either. I can't seem to trace it... has anyone seen this before, anyone have an idea where it is coming from ???
