Cabin leaks are never a good thing, and this one is no exception.  The owner stated brown fluid oozed out of the cabin roof at infrequent intervals – sometimes after a good rain, other times after the boat was healed while sailing.  Investigation revealed the coach roof and cabin side coring showed high moisture readings.  Water likely entered through a sail track in need of re-bedding, just one more example why all deck hardware should be pulled and re-bedded at least every 5 years.
