non-skid deck spider web cracks

[ole yeller]

I'm realatively new to both this site, and as a SeaCraft owner. Within the past month or so, I've noticed some hairline spiderweb crakcs that have begun radiating out from the points where the T-Top is bolted to the floor. They don't seem like a big deal, but should I be concerned?

I've owned lots of boats before, so I know Spiderwebbing is common, but I've never encountered it in the floor liner before...
