GSL Slip Renters. Current weather models is predicting a significantly high wind event for Monday. I recommend that anyone with a boat in the marina come out this weekend and check them. Check your dock lines. Check your sail covers and boat covers. Check to make sure all your property at the marina is solidly secured so that it does not become a projectile.
