Tha appears to be a gelcoat crack. Normal wear and tear and if isolated to the GC, will not leak. Welcome to the world of boating. Could have started from a impact, impossible to tell from a picture like this, the gelcoat, which doesn't give like the underlying fiberglass will crack and the fiberglass flexes. I have a area on my boat where a couple converge and make a "loose" area of gel that of I was to pick at it I could get it to come off. Like posted, all ypu could do is have it looked at by a expert and document of it is indeed deeper than the GC and fight with insurance. If it odds just the GC leave it alone.
