Dominica, the 15nm difference
I read in the Doyle island Guide about Dominica and how the southern end of the island had so much to offer in hikes, diving, snorkeling, etc. I spoke with our captain about stopping here first before moving to the north end of the island. He said the capital city of Roseau was considered a dangerous anchorage and we should pass it by for the safer anchorage to the north at Portmouth.
