Okay, Let me beat this dead horse some more.
1) The gas units used in Marinas
in the Miami
area can't be heard more than two boat slips away. They are pretty quiet and when someone is cleaning
, it's almost impossible to tell.
2) As a Hookah owner (Brownie) and a SCUBA
Instructor, I encourage you to do two things. A) Become open water
certified. B) Take the on-line course that Brownie offers at no additional charge.
Failure to do either of those can (and usually will) result in severe injury and possibly death - even as shallow as 12 feet of water.
Hope this answers your questions.
Best of luck
