FWIW "Big Pass" is a Pass in Name Only. What channel there is moves around alot with every storm and shoals quickly with heavy rainfall runoff. Sarasota YC used to
survey the channel and post safe
passage routes from time to time but whether that continues I am unsure as there were several grounding incidents for folks following the supposed "safe"
route.
Hopefully you are at a good yard and your
repairs will not be too costly. Wishing you good luck on that score.
FWIW...
PS: In a sailboat , one should avoid being towed in reverse at all costs. Better the heel the boat and rotate her than be dragged out stern first. You see why.
