Randy, This type of concern is part of what I do for a living. I would agree that you should not breathe air from a standard compressor!! It could conain lethal concentrations of carbon monoxide. There are a number of suppliers of low pressure supplied air systems that should have web sites. You could try MSA (Mine Safety Supply), Scott, among others. If you do a search for breathing air or supplied air respiratory protection you should find several suppliers. Anything you use should be certified by NIOSH (National Institutes of Safety and Health) or a similar Canadian agency. You might also want to consider using a confined space type blower to force a large volume of outside air into the boat while you are working. You should also be able to find suppliers for these on the internet.
