Scuba Diving

Martini's Law is first and foremost a dive boat, built to bring ocean boat-diving experiences to the inland lakes of Oklahoma and surrounding states.

Lake Cruising

For some reason, just about everything is more fun on the water.  Going for a cruise on the lake is a great way to unwind, and you'll always find friendly faces on board Martini's Law.

Scuba Continuing Education

Working towards your Adventure, Advanced, or other certification?  Divers who train in lakes are often more confident in the ocean, and divers who train close-to-home get to enjoy more leisure diving abroad.  Martini's Law always recommends ScubaBros for top-notch PADI dive instruction.  Call ScubaBros to enroll!

What's in a Name?

What IS "Martini's Law"?

Martini's Law is the established scuba diving adage which holds as a mathematical law that nitrogen narcosis gives a diver the intoxicating feeling of one martini for every 33 feet that he goes below 66 feet.

Here's the equation:

(Depth in feet - 66) / 33 = Number of Martinis

Sounds... fun? Scary?

Popularized by terms like "rapture of the deep" and "narc'd", this phenomenon is actually well-known among certified divers and it's risks are managed through safe buddy diving practices... which includes waiting to drink alcohol until after your diving is done.
