Never mind all the damage a few tanks can do to your boat as you hump them to the dinghy and back. Then what are going to use to fill them in; the sea, a big tank, or just fill them hot? And to top all that BS off, you are going to have to securely store several bombs filled w/80 cu ft of 3000 psi? Sounds like fun to me!
10 day dive package in the maldives for 2 people is 16K US, week and a half of diving or sink the cash into a compressor and gear and spares?
securing the gear is no different then securing anything else, secured is secured

id get the compressor a jr Bauer and setup with spares like a dive shop and dive where no one has dove before

It probably costs that much to sail there, too. But we aren't talking liveaboard dive "packages" here, are we? No, we are talking one or two dives a couple times a week once in a while, w/a local dive operation wherever you are located.
But, as I said, if you want to dump all that money into something most people who have them have done (and I've run sailing boats that have had good dive compressors and gear aboard, so I am talking from experience), for less time diving than filling tanks and maintaining the equipment, then by all means please yourself.
And please, do tell, where exactly do you think you can go today to "dive where no one has dove before" on this planet?
Never mind many countries here in the Caribbean and possibly in other places, do not allow independent diving any more. Many require you to dive w/local dive operations, PERIOD!

Re: Scuba tank system on sailboat

^The world is a lot bigger then Capta's lil ol caribe..Sure, we dove in all kinds of spots,,just off the boat, that maybe nobody else had ever dived before...Galapagos, French Polynesia, Tonga, Fiji, Vanuatu, New Zealand, Australia, Indonesia, Phillipines, Thailand, Malaysia.

We were never subjected to any sort of "NO DIVING" kinda BS. Maybe some are just a bit past their use by date for exploring the undersea world...

The cost alone on training on a rebreather would almost exceed the cost of an onboard compressor..

When I was 16 I got a job at a large suburban YMCA. They had a large pool and complete aquatics program that included a scuba club that met there and offered scuba lessons. They had a compressor there that someone had made from an old Harley panhead engine. It was driven by an electric motor and included a pressure monitoring gauge and water extractor.

I got about 20 minutes training on how to fill the tanks and it became my job to fill them. On the night after scuba class I would refill all the tanks. Also there were times when they took the class out on weekend diving trips to area lakes and I filled all of the tanks after those trips as well. I did that for about 2 years and that homemade compressor worked well the whole time. Of course back then, there was no Nitrox or Trimix. It was straight compressed air.

If you're cruising anyway, the cost of cruising doesn't matter. If your already diving with your own gear, then the costs of scuba gear don't matter. The financial picture then comes down to the costs of the compressor and it's upkeep vs the costs of diving with someone else (using the 'go pay to dive with someone else alternative).

A 2-tank morning dive with Stuart's Cove in Nassau will run you $134 per person. So you and your dive buddy/cruising partner are spending $268 to each do 2 dives. Diving 4 times per week will this cost over $1k each week at those prices.

Cruise the Bahamas and dive each week at those prices for 2 months and you could have bought your own compressor and generator and had plenty of money left over for spares.

I haven't checked everywhere, but I'm not aware of any requirements to dive with a guide in Aruba, the Bahamas, BVI, USVI, Tortuga, etc etc.

The more I hear about cruising the Caribbean, the less interest I have in doing it. This is a perfect example of why. "Not allowed" unless you pay a local?? Talk about protectionism.

Re: Scuba tank system on sailboat

A possible alternative to tanks and a compressor is a dive hookah system. Takes up much less space onboard, and you are not reliant on shops to fill your tanks.

Re: Scuba tank system on sailboat

Look at names like Brownie's Third Lung (Fort Laud). A real compressor for dive tanks, that produces DIVE QUALITY OIL FREE AIR, with moisture traps and filters, ain't small or cheap. And they need more than AA cells to run. It is not impossible but it IS a major undertaking, you're going to need a lot of diving to make it pay.

Some countries will not fill you US-stamped tanks, just as the US won't fill other tanks, and many Canadian shops won't fill US tanks. And then there are some countries like Greece where they are afraid divers may be stealing antiquities, if you don't have a local permit to dive...you go to jail.

By renting tanks locally you can lose spontaneity, but also save a lot of "stuff on the boat". And if you get your own compressor, the filters and maintenance aren't trivial, and not attending to them can be deadly. You might want to look into DAN or other chamber and medevac insurance as well. Places like Indonesia have dive resorts that are 6 hours away (in daylight, by boat) from the nearest chamber. And in Hawaii, the last civilian chamber is being shut down. Be careful, please.

Re: Scuba tank system on sailboat

I'm not sure what "OIL FREE OIL" is exactly, but yes Brownies are good systems that don't put oil into the air. A good dive set with traditional tanks aint cheap either.
But a good hookah can allow freedom to dive in remote places without the need for storing tanks, nor trips to the local dive shop - which in third world countries may be pumping up those tanks with who knows what kind of oil compressor. Just another alternative to tanks and filling.
