Hey Dave,
Very few cruisers have ever gone to this anchorage according to the owner of the resort on this bay. He has only seen one other sailboat in the past several years. The Explorer charts are being updated to show the passage to get to this area. Even the Explorer charts show very skinny water in this entire bay.
We will be leaving spring 2013 for a 3+ year cruise.
Sorry for the long delay in reply.
Don and Lana
