Just saw a credible post on another site about a grounding north of Saba Rock. An eye witness saw the Leopard 45 cat passing around the NW side of Saba (the marked channel is on the other side) toward Eustatia Sound at a fair clip and grounded on the reef. A boat from Saba pulled them off. Pretty amazing, IMO. I've taken a RIB thru there before, slowly. I can't imagine trying to take a full size sailboat thru. There was another serious grounding at the west entrance to North Sound about a month ago.
Yikes!
