Structure cracks, am I sailing her to hard???

[gmakhs]

Hello,
The boat is been sailing from storm to storm the last 2 years, but never been grounded, inspecting the bilges I found those cracks, scratching a little bit seems to be only the gelcoat.
I plan to remove all the gelcoat in the area soon and inspect for scratches in the fiberglass.
Is it possible this kind of stress to occur from sailing?

Beyond my expertise. But if those cracks run athwartships, then I would suspect the gelcoat was cracking because the hull itself was being bent like a banana, perhaps from the forestay and backstay being overtightened, causing the ends of the hull to pull up. That would explain the way the cracking is all in the same direction, rather than random checkering. Gelcoat which was applied very generously sometimes cracks because it is not flexing the same way that the FRP under it does, so I'd check the tension in the stays before grinding things down.

Thank you for the information, I will check the tension in the backstay, the stay tension was adjusted 2 months ago from a selden dealer when I purchase the new roller, I will check the tension and repair the gelcoat it's generous indeed.

From the appearance of the cracks it does appear to be some flexing of the hull. Yes, grind down through the gel coat and inspect the underlying fiberglass. If it's just the gel coat no worries but if it's the cracked you may need to grind down and replace the fiberglass layer with some new cloth. Even though I do not think this is a serious issue.
