When diving off of a boat, you might be tempted to bring everything, just so you are prepared. As a boat operator out of Florida, I beg you, please don’t. To help with your decision making process, I have put together a list of essentials that are always welcome when you dive on my boat.
Dive Equipment- 
Most of the smaller items should be attached to your BCD or in a pocket
Spare Parts Kit –
Can be packaged in a small bag or dry box
Personal – 
Should be carried in a small dry bag, so please leave the beach towels at home and bring something compact.
