I recently picked up a small piece of netting half way between two islands in the Azores, cleared the net in a marina using the traditional mask, snorkel and much gasping. But then saw a Danish boat with the same problem but he had a small "oil free" compressor a length of pressure hose and a SCUBA mouth piece so he could work easily on the prop. Can anyone help with the specification of the equipment to do this as I fancy having this as an emergency kit option.

We have a portable Brownies Hookah system: http://www.browniesthirdlunginfo.com/vs-hand-carry-portable-brownies-electric-recreational.shtml

It has been great for doing work on the props (adjusting the pitch on our variable pitch props as I tuned them) and cleaning the bottom of the boat. The couple of times we have hooked lobster pots or floating lines, I have not bothered to get it out, but it would certainly have worked fine if I hadn 't been able to clear the lines quickly with a snorkel. Running on 12 volts, you can 't go very deep with it, but for maintenance projects that is not needed.

As posted before, you should get some training for any compressed air system. Brownies does offer an online course as part of the purchase cost.
