So worse a failed trunk is a water covered boat...but should not reach the battery height....
Did Zodiac (France) themselves tell you that or did your Zodiac dealer tell you that? If your local Zodiac dealer is as knowledgeable as my local dealer then I'd recheck any advice they provide through other sources
That does seem like very strange advice. Those little rubber flapper diaphragms that zodiac uses for their valves will allow some water to slowly leak back into the boat when the boat is not moving. Definitely put the plugs in when moored.
