Hi all, am new to ribbing and need some help and advise
The rib is a new Humber Assault 5.0m.
Have used it once without issue, but am noticing that the rear tube is losing pressure (significantly). Thinking originally that this was cold related I reset the pressure in the tubes so that the 2 adjacent tubes were the same pressure. For 10 days all ok, and on Monday was working on the boat and it was all ok as I was looking at the transom adjacent to the area.
Go out tonight to find the tube deflated once again.
Cannot understand why this is the case as if it deflated gradually it would lead to a slow leak, but this seems to be fine then a big leak. Have done a search to look for the leak, but it seems very puzzling.
Any help and advise would be greatly appreciated.
