Leaving boat in the water

I had an issue with my Coastline trailer this weekend and can't get my boat back on until the repair is complete. I was lucky and have friend with a house on the water in Corpus so I tied the boat to his dock and took the trailer back to Austin for repair.



My question is: How long can I leave the boat on the water without causing problems? I may not get the trailer back this week so it may have to stay on the water for two weeks.



Is that a problem?



Thanks.
