lund pike 17...three rivets leak slightly...big problem?

I noticed after it rained and my boat wasn't covered that there was a "drip, drip, drip" coming from the front centerline. Turns out three rivets appeared to be letting water out of the boat. None of the leaks was more than the finest thread of water, and together they accounted for maybe a drop every five seconds.

Should I be worried? Is this something that I need to address immediately? We just had the boat in the water for an entire week and I never noticed it filling up, though with the rain, I was running the bilge every other day anyway.

Thanks for advice.
