Twin Worthington HP 130 tanks used for 30 M Club encounters
Sex underwater: The idea of underwater sex, mostly SCUBA equipped dive-sex out here, seems to fascinate my readers. Perhaps that’s because it is such an exotic setting for a sexual encounter with the problems of pressure equalization and dehydration, nitrogen buildup and lubrication. For a less expensive underwater sexual encounter extended snorkels can be used in calm water or a pool, but limit a couple’s maneuverability to shallow dives or frequent returns to snorkel depth.
A variety of suits can be worn from a bikini to a drysuit, not that a woman can be successfully penetrated while submerged in a properly functioning drysuit, but she can be caressed to a clitoral orgasm with a vibi or with an experienced man’s fingers if her suit is deflated until her groin is squeezed which can be awesome if you are with the right guy!.
Adolph and the 30 Meter Club: Adolph has agreed to let our escort trainees qualify for the 30 M club in his 62 M deep training facility. Until now our trainees have been using my 20 M pool, the pit, to train, but none of them could qualify locally for the 100 ft / 30 Meter Club, until now. Anya and I became members with Chuck in the cove at my place on Virgin Gorda several Christmases ago. For dive-sex training we use single HP 130 cu ft tanks worn high in the bottle clamp of an escorts buoyancy compensator so that the woman can be penetrated from the rear w/o her tank getting in the way. For actual dive-sex at 30 M we use twin HP 130s on a wing BCD (I wear a SeaQuest Raider modified with a SeaQuest Diva LX bra and harness) so there is sufficient bottom time for the couple to savor the thrill and give the encounter the attention it deserves w/o having to rush. There is more about the calculation of bottom time below.
I’m often asked by dancer friends who aren’t divers how we determine the size tank to use and the bottom time for a dive including dive-sex. While training for entry into the 30 M Club we use approximate calculations that work well with a good safety margin and a woman won’t be inducted into the 30 M Club unless she is an experienced diver with good breath control, not that she isn’t going to suck a lot of gas (sometimes 3 or 4 times normal) during arousal and orgasm.
Typically an experienced diver escort’s surface air consumption (SAC) rate can vary between .5 and 1.1 cu ft and during orgasm it can rise to 2.5 cuft/min or more. For dive-sex training we assume an average of 2.25 cuft/min. If we assume a surface air consumption rate (SAC) for dive-sex of 2.25 cuft/min x 5 min = 11.25 cuft on the surface.
Bottom time: at 100 fsw (4 ATA) 11.25 cuft x 4 ATA = 45 cuft divided into the tank capacity 130 cuft = 2.8. To get bottom time in minutes: 2.8x5 = 14 minutes. But that is w/o any rock bottom time air for ascent and deco.
If we assume a reserve emergency / ascent gas of 1200 psi in a HP 130 for a dive to 100 ft (30 M) that is approx 30 cuft that must be subtracted from the total to calculate usable gas for bottom time. 130 cuft – 30 cu ft = 100 cuft. 45 cuft divided into 100 cuft of usable air = 2.2 x 5 = 11 minutes of usable bottom time at 100 ft with a 130 cu ft tank, which is why we induct members into the 30 M Club using twin HP 130s which should easily give a woman 20 to 25 minutes of bottom time at 100 feet for dive-sex unless she panics. Another reason for using twin HP 130s is that Adolph’s facility is 200 feet deep and if there is a buoyancy problem the additional air might keep the diver alive (if nitrogen narcosis didn’t get her) until s/he could deploy a lift bag and get to the surface. The specs on the Worthington X8-130 are:
*Volume: 130 cubic feet (16.0L)

The specs on the Worthington X8-130 are:
*Volume: 130 cubic feet (16.0L)
* Service Pressure: 3,442 psi
* Outside Diameter: 8.0"
* Weight: 43.0 lbs (empty)
* Height: 25.5 inches* Width: 8.00 inches
* Height: 25.5 inches* Width: 8.00 inches
* Buoyancy Empty: -2.0 lbs
* Buoyancy Full: -11.7 lbs
The tank buoyancy characteristics allow shedding a few pounds of lead from the weight system so after a dive with a twin-set there will be about -5 lbs. The 23 lbs when the twin-set is full can be easily handled by the SeaQuest Raider buoyancy compensator. Of course there is no offsetting buoyancy from a wetsuit because if any encasement suit is worn it’s latex with almost no buoyancy except for a tiny amount of trapped air.
Bottom time while training: In my pool (the pit) at 68 fsw (3 ATA) 11.25 cuft x 3 ATA = 33.75 cuft divided into the tank capacity 130 cuft = 3.8. To get bottom time in minutes: 3.8x5 = 19 minutes. But that is w/o any rock bottom time air for ascent and deco.
If we assume a need for emergency / ascent gas of 1200 psi in a HP 130 for a dive to 68 ft that is approx 30 cuft that must be subtracted from the total to calculate usable gas for bottom time. 130 cuft – 30 cu ft = 100 cuft. 33.75 cuft divided into 100 cuft of usable air = 2.9 x 5 = 14 minutes of usable bottom time at 68 ft with a 130 cu ft tank. The reserve air in this calculation is high and can be trimmed to give a diver another 5 or 6 minutes to extend the bottom time to 20 minutes in my pool w/o pushing the envelope.
Positions: In early DS training and at 3 ATA at the bottom of my 68 ft deep pit we use a single HP 130 so rear penetration can be accomplished which is the best position for taking well endowed men. But for admission into the 30 M Club where dual tanks are necessary woman astride is the preferred position as that is where a couples tanks are least likely to get in the way. I have worn my dual 130s so high that I can’t tip my head back to look up just to get the booted bottoms of the tanks out of Jacques way so he could take me from the rear but with the tanks that high it’s throws my center of buoyancy off – not a good thing - so woman astride is the most comfortable for a really intense encounter. And a woman who can ripple grip a man while astride 30 M down is really in the saddle for sure!
In Adolph’s well to maintain a constant depth and away from the walls we use ankle leashes to hold both the guy’s ankles at a fixed depth and inflate his buoyancy comp. to hold us there so the girl can sit astride and grip him with her vaginal muscles and legs. And, as I mentioned before the dual 130s are a safety factor for any possible buoyancy problem in the 200 ft deep facility.
Surface supplied diving and bottom time: Tank related bottom time problems can be eliminated if a diving facility has the ability to provide surface supplied air as my pit and Adolph’s well training facility do. Then a diver’s bottom time is determined by the gas s/he is using and nitrogen loading, determined by recent dive history. Both Adolph and I use Kirby Morgan helmets with the tri-valve exhaust which with Tri-mix can be used as deep as 330 FSW (100M) so the bottom of Adolph’s well at 210 ft is about mid way. Escorts are inducted into the 30 M Club wearing twin 130s so they know how to use that equipment since very few divers have access to surface supplied Kirby Morgan helmets.
The rest of the story: If you watch 30 M Club dive-sex videos on the internet you hear the theme: “Get down, get off, get up” because of the bottom time limitation of typical tank sizes since few recreational divers have access to dual 130s for a relatively leisurely boink at 30 M. No one talks about the woman’s pleasure or the problem of lubrication or the need to use a gas guard and there isn’t much about staying off the bottom while in open water so you don’t get mud or sand in the moving parts. The videos seemingly are made for guys and the woman’s contribution is to provide a hot tight vessel for the guy to shoot his wad in. I don’t think it’s an indication of guys hatred of women it’s just that so many of them don’t know enough to ask (and neither do the women) and are thinking only about their own pleasure.
