I’ve been back and forth on getting one for years. Issues remain
Storage. They come in a hard box. They take up room. Where to put it.
Electrical v gas. Electrical seems just fine for boat work but a PIA for recreational diving. Most of our snorkeling is- anchor, deploy dinghy, take dinghy to site then dive. So once again size matters. The device, two or three people, lunch, boots if we’re going hiking, lunch, water etc.
Which one (brand) to buy.
We’ve taken to moving after a week or so if anchored in the same harbor. Scrub chain best we can and running it through windlass seems to keep it pretty clean. We run fresh water on it and when we have access to a dock hose flush out the chain locker.
With a diver costing ~&100 and a dive every 4-6 weeks still holding off on the hookah. Also usually end up with a short haul every 6 months for thruster zincs or other maintenance anyway. Sometimes those zincs are a ***** to change. What I want is to see things I can’t with the snorkel. Oh well.....

I started to look at getting one even though on paper it would take a few years of getting a diver to clean the bottom to pay for itself. But getting a diver requires that I'm somewhere where I can get a diver and there's costs and time involved in waiting for one to get around to an unimportant transient boat they likely wouldn't see again.

Wondering if anyone out there has tried building a hookah system around this compressor...
https://pacbrake.com/product-lines/hp625-air-compressors/

Operates on 12 volts. Produces more than 2 cfm at 90 psi. Rated for 100% duty cycle. Used as the OEM compressors for a number of cars and trucks that have air-suspension and air-brake systems. Seems like it should be more than adequate, while costing a lot less than a Thomas and only needing 12 volts (though, obviously, at pretty high amps).

there's self build system plans online

I figured the cost equal to 1 anchor and 120ish ft of chain.

You may find building your own system fun and with some cost savings. I didnt....but building several..yes.

I have the airline 12v w/60' hose for a 42' boat. I paid $1,500 for the unit and an additional $100 for the aluminum deck plate with the vibration isolators. The plate has two handles which makes moving the unit much easier. I store mine in a lazerette and pull it out into the cockpit for cleaning. The 60' hose is probably a little overkill but that's the length that came with the unit. I think a 50' would be ideal.
I'm located in the Stono River in Charleston, lots of growth here so having a diver clean every 3 weeks during the warm water months was expensive, and I really like laying my eyes on the hull of my boat.
I have zero scuba experience, never taken any course but have done plenty of snorkeling. Some here on sailnet would call me an idiot for risking my life, I consider myself to be reasonably intelligent and safety conscious person. I've done a fair amount of research on diving safety and am familiar with the dangers of diving deep. I feel quite safe diving to a depth of 6 feet, my boat draws 5'-4". I have no desire to go any deeper I purchased this rig for the sole purpose of maintaining the bottom of my boat.

As a SCUBA instructor, I recommend that anyone planning to use a hooka system get at least some basic training in using SCUBA. A change in depth of only 4 feet of seawater can cause a pressure change of 2psi - enough to cause an overexpansion injury (arterial gas embolism, pneumothorax, mediastinal emphysema or subcutaneous emphysema). An alternative might be to hire a certified diver to clean the hull. For the cost of a quality hooka setup, you could hire someone many times over and avoid the risks. Better yet, if you have a friend that dives, they'd probably do it for a post-dive beer (or two, or three..) and maybe the cost of an air fill (about $8) if they dont have their own compressor. Fair winds and a clean hull! Cheers

The compressor on a hookah, or that the dive shop fills tanks with is different. This compressor is not concerned with removing contaminates (dust, dirt, oil, etc) from the compressed air, which under pressure, is really really really bad for you. Maybe drop in at a local dive shop and run the idea by them for a tecnhical explanation of how that can kill you.

I once needed to borrow a 12VAC hookah from a friend who maintains a charter fleet. He had been using his hookah for years. The compressor was labeled "Central Pneumatic." :eek:
I believe that it was this one:


After I changed my zinc, I returned it and have not borrowed it again.

No, it's not. As has been mentioned several times, all of the commercial hookah systems use compressors that were originally designed for other purposes. NO ONE builds a compressor from scratch specifically for use in hookah systems.

And, by the way, I was planning to add an air filter anyway.

The question remains... The Pacbrake HP625 -- based on its specifications -- appears to be very well suited to hookah use. So I'm still wondering if anyone has built a 12 volt system around it. At this point, I'm beginning to suspect the answer is "no."
