    Does'ent look to bad so I would suggest filling with 2 part epoxy, sand and paint, or you could even use some fg resin and fill,smooth, paint.

        That looks a little more than cosmetic. It's cracked across the seam along the sides and transom. Looks like possible structural damage in the fiberglass. I would grind down the gelcoat anywhere there is a crack and look for damage in the fiberglass. Saturate any areas that are damaged with resin and maybe lay a little glass cloth over the area to tie all together nice and strong. Also see if it is possible to reinforce it from the inside. I'm afraid if you just fill it and paint, the cracks will come back or the hull may even separate in a bad tumble. Does any of the exposed fiberglass give with light pressure?

              Water leaking is a sign that it will need to have some cloth cut, resin applied and some sanding to do. All the cracks in the gel coat will need to be addressed as well so they do not continue to spread. It is not impossible but will require some time. I repaired a miss geico that had similar damage and the next run out when it flipped it cracked the entire side that had not been fixed. Pro Boat and Aquacraft rtr boats could all use a little extra hull reinforcement if you plan on running them above their stock parameters.

                How did u do this damage to the hull in the back? I guess my mystic was built like a tank (knock on wood) because the other day I was running it and a little air got underneath it lifted it and I let out and turned SLIGHTLY because I had it at an angle towards the shore so if it did flip I can grab it without swimming, and as soon as it turned it caught an edge flipped and at the moment I swear I had to change my pants because the thing flipped onto the beach and tumbled a couple times. I thought I was gonna have MAJOR structure damage but it had NOT one crack! Safe to say I got lucky this time!

                  All the info above is good, you really need to evaluate the damage,I haved repaired split seams with epoxy but also was able to get some fg cloth on the inside of the hull also,
                  and mine is water tight.

                      Don't you have a break a way rudder? or did it hit hit the strut?
                      eather way that #$!%$*.
                      I once lost my strut assy with shaft and prop on my UL-1 but some how did not do any damage to the transome and the nut plates were still intact, go figure.

                          Is their a small brass screw in the rudder, if so then the rudder bolts are to tight to allow it to break a way. just a thought.

                              No they don't come stock with a break away rudder! But I have always been nervous about hitting stuff in the water!!! I'm SUPER careful to stay out where I know there's nothing! Lol
