Huh. Thats what happened to mine, and now I have a thread under "HULLS" about ripping out floatation, and everything rotting. Mine got flooded last June, and has been stored inside since that time, but still has some trapped water in it after almost a year. I now have a few holes in my floor with fans running hopeing to dry out, and save my boat. However, I have been around boats my whole life, and every one I have ever seen has been left out in the rain at one time or another, and got drenched. Most boats "usefull life" is over before they ever rot to a point that makes them unsafe, but jet boats seem to "live" alot longer than a normal runabout, so I try to do all I can to keep mine dry.
