Hello everyone!

I recently bought a Mistral Equipe 2 that needs a refit. It looks similar to the board in the first photo (although mine is in a worse condition). I read somewhere that the XR model had a larger, rounded daggerboard, like the bottom one in the second photo, which is what I have. Can someone confirm whether it is a XR or CHS ?
Also, my board has an aluminium tape repair right in the middle of the hull at the tip of the V-shape. The area feels a bit soft over about 7 cm diameter. Does anyone have advice on how to make a proper repair, especially what materials to use and how to make sure I keep the correct shape of the hull?
