No real towing companies like TowBoatUS or Seatow there. But if you run into trouble fellow cruisers or locals will help. If really badly aground (like blown up on rocks in a storm) there is a salvage company or locals might organize something. No towing insurance like Seatow or TowBoatUS. Bahamas is a big place, a lot depends on where you are. In many places you're really on your own. Most groundings are easy to get off if you're careful. Very few run aground as the water is so clear and you learn to read the water. There is BASRA (Bahamas Air Sea Rescue ) but they are a volunteer group mostly around Nassau, very few resources.
