Sail Problems

First day from Beaufort, July 20, we are heading north out of St. Helena Sound towards the Edisto River and Watts cut.  We know we have to make Watts Cut before low tide.  So we are sailing along have both sails up the wind is with us today. Pretty uneventful day until ...... we get to the entrance to Watts Cut.  The winds have picked up to about 15 to 20 during the day and when we go to drop sail we jibe and our main sail rips.  As we prepare to drop the main it tears more and more.  Nothing we can do at the moment.  Then we are trying to to furl in the jib and the spinnaker line gets wrapped in the sail and it is flapping and snapping like crazy Joe finally gets it unwrapped and we try to head into Watts cut.  It is now close to low tide and at the entrance we touch bottom we are afraid to just plow through the rest as we will have to wait for the tide to come in and we do not want to run hard aground.  So we turn around and head up a small creek where we know there is enough water to anchor for the night.  It is getting dark and it is time to quit for the day. We will assess  the damage when things are calmer.
