Our 54 has a major design flaw. Or it’s not protected against stupidity, take your pick. Anyway I managed for the third time now to overflow the fresh water tank while refilling. The problem is that the water does not simply overflows through the filler cap. Instead it gushes out of the level meter pipe next to the companionway right into the main saloon bilge that has no drain. Oops. Anyone else has the same problem?
