Bob,
Colon is a big centre. Then heading east there are several refuges and even
marinas. These include the famous bay of Portobello -anchorage only but fair size town, most facilities. Further is Panamarina, and Puerto /Isla Linton. Even further is Green turtle cay marina. The next stop are the wonderful san blas islands where you can spend ages exploring but here one operates with the culture of the Kuna indians. I operate charters out here.
