Everybody is inventive enough to find himself a small niche in the services industry of the Rio Dulce. You will find woodworkers, motor engineers, dinghy specialists, canvas workers, sun hat makers, artist painters, glass fiber specialists, cooling system specialists and more. You will meet these rusty old sailors at happy hour at Bruno's or Mario's Marina or whatever place is 'in' at that time. If you are lucky some nice stories will come up about the good old times that there was only one place to hangout. For sure the Rio has changed in the last ten years.

Maybe a waterbus line will finally be installed so that you can go out during the night and come safe back to your boat.
