The only material I could get at the time was Black, so it shows up well in this image.
Thanks for the information. Adding a strip around the floor somes like a good idea. Currently I'm thinking about re-gluing the section that has seperated and then reinforcing the whole seam with a strip.
By the way, mine has an airfloor as well, I think it was the same problem, the airfloor and keel seemed to be pressing up and through the hull.
