Do any boats run from AC to Dangiriga or Placencia areas? Any chance on hitching a ride with fishermen or other boaters?

Looking to leave AC after the JJW Camp II and head over to one of those areas. Actually I want to go to Riversdale but am flexible on how I get there. I realize I'll have to go through BC if flying -- thought maybe there might be an alternative???
