After the boat was put back into the water this year, air loss can be noticed. Air escapes in several (now 5) places. This is always where a transverse seam runs under the skirting board. The air comes out from under the rubbing strip. The boat is now almost exactly one year old, the accumulated service life before the leaks occurred was less than 4 weeks, the boat spent the rest of the time folded up in the transport bag. It doesn't help that the boat actually looks chic.
