If your thinking about the "mini b" kit I would suggest getting a regular BCD and reg set and a small tank. Probably work out cheaper and you can hire larger tanks
if/when you want to do some sport diving
I think you''l struggle finding a compressor
that will run off a 1.6kw genset, about 2 kw is the smallest.
You can get petrol driven compressors that are fairly compact.
If you want a scuba
kit just for boat use i.e scrubbing the hull
, anchor inspection
then have a look at the various hookah set ups but they're not the cheapest.
