I've been checking out the geography on Google Earth. I'll be traveling from Boston next season through Woods Hole. Can anyone tell me which way the current flows through Woods Hole? West to East or East to West on an outgoing tide? Are there any opposing currents or trouble spots? Do the cans get submerged in the current? Is that Middle Ledge well marked? What time of the tide is the most difficult/dangerous? Is the 5 mile ride to Vineyard Haven in August ever a scary ride?
