GSL Slip Renters. Thick ice has begun to form in the south basin of the marina. This should pose no threat to boats. But you may not be able to get out of your slips and go sailing for a few days. Once the wind stops blowing out here, we will take Rescue One and try to stir up the water and break the ice. Also, the wind chill is SO cold out here, you probably don't want to be here anyway.
