Air tools and a compressor...
I thought I would throw this out there for those of you who enjoy using your air tools (I'm one of them) on your boat without the need to have a big compressor on board.
Backing up a bit... In my younger days one of my many hobby's was racing cars and with that I used air tools extensively both at the shop and while at the track. At the shop using a compressor was the obvious choice but while at the track having to bring everything needed for race night (tools, pit mule, spare engine/parts/tires, etc. etc) in a car hauler trailer and or the back of a truck pretty much filled up all the available space. Then having to add a compressor to the already very long list of items needed for race night was over the top. So, to get around having to lug a large compressor to the track, I powered all of my air tools with a large bottle/tank of nitrogen, the same bottle I used to fill my tires on the race car.
What I'm getting at is that on a boat, just like in my car hauler, sufficient space is often times very limited so my solution to not having to bring aboard a large compressor (along with its incorporated storage tank) to power my air tools will be to use compressed air stored in scuba tanks. Since my boat is already spec'd to include a Bauer electric compressor to fill my scuba tanks this seems to be the perfect solution and this way I can kill two birds with one stone... Scuba dive and power my air tools.
