Hey, new owner of a 1995 Beneteau Farr 50 here. When filling my four fresh water tanks, the top tray of the water tanks fill with water and, if left overflowing at the hose deck fill, will flood the bilge as well. Has anyone else had this issue? The clamshell tank vents don't ever seem to flow when overfilling, so one of my suspicions is that they might be clogged. As a boat owner of many years (but new to this model), I'm perplexed.
