Ok almost ready to go....

[maui jim]

Fish finder, glow sticks, 2 headlights in case one goes for a dip.
Big flashlight to scare away large boat heading towards you. Water, or gatoraid.
Quick reaction to smack annoying seal from jumping on your yak.
Know not to grab the morey eels they really dont like people out of the water.
Nor do sting rays for that matter...
Watch out for gooey ecky thing that somehow crawl into the hoop. Cound never figure those things out, and they do no taste like chicken.
And go with a friend...
