Port propane holder modified for a scuba tank

[Tucsonsailor]

Hi All:
I own a 380 Hunter. As you who own this boat know there are built in containers on the port and starboard stern of the 380 that facilitates to propane tanks.
Has anyone given any consideration to modifying one of those for a scuba tank. My thought process is that if mounted in one of those areas, I could use a hookah line and regulator and then have the ability to clean the bottom of my 380, without always having to store my tank elsewhere. I can have a smaller tank than an 80 CF, but just wanted to test the waters with any Hunter owners to determine advantages or disadvantages.
Your input would be appreciated.

Thanks,

Have you considered a pump, surface supplied hookah pump?

Hi Thanks
Yes I did, however they make two kinds as you probably know. Gas and electric. I didn't want gas on my boat, and I thought it would be more trouble hooking up a compressor system to the batteries, (which is the way I would want to do it) than configure the port LPG area for an air tank of some type. Your thoughts?

First, I'm a certified diver, 'though I haven't in quite a while. That said, I'm a bit of an equipment nerd, and I have a variety of equipment including a scuba compressor. The issue, as I see it, is bringing the tank back and forth for refills. A 12VDC hookah compressor is available. If you are at a dock with AC power, no problem. If on a mooring, you might want a mast as an air intake, since you might have to run the engine to keep up with the power draw. But, I prefer the hookah compressor solution to the tank. But for me, it's all speculative, since I'm not doing it!

I am a certified dive-master, and I use an older gas powered Brownies Third Lung hookah system for this. It weighs about the same as a scuba tank, but you don't have to go back to shore to refill it. By adding an extra 100 feet of hose it makes it really nice to be able to explore shallow reefs while at anchor. If we want to explore more, we put it in the dinghy, and go.
