At Castine, the waterfront belongs to the Maine Maritime Academy and its training ship rather than to commercial cargo operations. Set on Penobscot Bay, this very small Maine harbour offers deep natural water but handles no container, breakbulk or customs traffic — its role is maritime education and recreational boating. Freight bound for the area moves through Searsport (Mack Point), Maine's principal bulk and breakbulk port on the same bay, or through Bucksport on the Penobscot River.
