This inflatable boat needed a local aid in various parts of the airlock.

For a start we placed a couple of aid to the right to the left of the chamber in places that had some scratches and lose the airlock, then we decorated the bow with a big piece of non-slip rubber by thinking about the end at this point (don't you slip and don't you rubbed the balloon with the rope of the anchor). Still in the back and bottom of the chamber and the movies of the cone ξεκόλλαγαν as at this point grow large friction for this reason, we placed two large aid (τακουνιά) to eliminate the problem. Finally, we washed the airlock with specialized cleaning fluids and spent emulsion of silicone for the best protection.
