… I wasn't there, so I can't say. But, I wouldn't exactly call 6' to 8' foot seas and 20-25 kts of wind off the coast of California "rough conditions", would you ? Isn't it like that pretty much most the time ? I'm guessing they had a bit of water siphoning from a water tank or back in from one of the discharge thru-hulls, or the Head was overflowing ...
