[PSUBS-MAILIST] New video of bathtub submarine

Tue Jul 11 16:32:34 EDT 2017

Some time ago we were discussing the "Chinese oil barrel submarine"
& didn't think it safe to 15ft let alone the 30ft he thought it was capable
of.

   I got in contact with the builder via the reporter who had written the story.
The reporter said he had grave concerns at the time. I conveyed some
basic safety procedures like testing unmanned, & putting in a flood valve.
He looked at our site & was very impressed & appreciated our concern.
 I believe some psubbers also contacted an American teenager who was building
out of a plastic drain pipe.
Perhaps one of the European Psubbers could get in contact with these guys.
I thought at first this must have been an ambient sub, but looks like a 1atm
bathtub.
In the video above, the oil barrel submarine runs in to trouble!

They volunteered to "talk" to the owner to set it up (big mistake). Next thing I knew, the owner told me that a group told him about all the safety features that were needed to avoid the "danger". Not wanting the "danger" at his marina, he decided not to allow subs there anymore, including mine.

They said yes and gave me free use of the visitor center to boot. We had about 6 subs that year and had a great time. I kept my sub at Raystown for another two years diving it with no problems (or attention).

Good because they are requiring some safety items that will weed out the nuts. Bad, because now we are "on the radar". Today we already have fewer places to dive than just a few years ago.
