Extra Tank

It just occured to me that we have not accounted for an extra tank in our daily needs, and it’s best that we do so.

All dive shops will toss on the boat at least one extra tank. Example:

6 divers x 2 tanks each = 12 tanks

1 dive pro x 2 tanks = 2 tanks

12 + 2 = 14 tanks obviously.

This boat still needs a +1 extra tank.

Thus, 14 + 1 = 15 tanks would be needed for this activity.

We will need an extra tank for every boat that departs, and every shore dive activity.

Some shops may use two extra tanks - one for air and one for nitrox.

But yeah we want our boat crews and tank guy getting that 15 tank number and not the 14 tank number. However we can get a +1 on each activity.
