The Coast Guard announced on the VHF radio that there would be a special security zone around the ferry Island Home. They did not identify the route that the ferry would take, although they did give a time. All mariners needed to stay 250 yards away from this vessel. Don't you just know that Island Home, with it's 3 Coast Gaurd vessel escort turned out in front of us in Woods Hole. Woods hole is a narrow channel with rocks on both sides and STRONG 3 knot current! We were able to slow down enough to let the ferry and the escort get well ahead of us. Below is a picture of our track through Woods Hole.
