Mask, fins, and snorkel -- yes, you do not need to dive to see the sharks, but it is nice if you can!
SCUBA gear -- optional, you can see the sharks on snorkel from the surface cage called "The Playpen." A three to five mil suit is considered optimal by most for the half-hour dives most divers do.
Extra Weight -- you will be diving near the surface, typically no deeper than ten or twelve feet, so your wetsuit will be very buoyant. If you are in the cage and the surface is a bit "bumpy" you will need a good six or eight extra pounds to stay planted on the cage floor while enjoying the shark action all around you.
One tank per diver per day -- the diving is shallow, maybe ten feet or so, and one tank will be plenty!
Seasickness meds -- the TransDerm Scope patch is best for most people. The conditions can be a bit "bumpy" out there, particularly late in August or early in September, and we already have plenty of chum for the sharks and don't really need your personal contribution... but no worries, you wouldn't be the first to help chum for the sharks!
Sunglasses -- preferably polarized, always the best when out to sea.
A floating strap for your sunglasses -- always a good idea for your glasses when out to sea.
A hat with visor or wide brim -- with a string to hold it on, also best when out to sea.
A sweatshirt or jacket -- it can be quite chilly in the morning!
Beverages and Snacks -- water, juice, soda, chips, sandwiches, cookies -- whatever you like -- if you don't bring it you won't have it; there's nothing for sale on the boat!
Towels -- bring one if you want to dry yourself off.
Something to read -- it's about two hours out and two hours back on the boat, so you can sleep or you can read.
Cameras! -- topside and underwater. For topside, a 50mm 35-70mm zoom will probably be best for shooting sharks at the surface or when they follow the teaser bait up and out of the water. Film will depend on available light, but I use 100 speed with flash fill in sun and in clouds. Underwater, a wide angle lens will be best, something around 15mm or 20mm, with a strobe for when the sharks come in close, which is often! I use 100 speed film on sunny days, and push it to 200 on cloudy days. Disposable cameras with 400 speed film will work pretty well on sunny days, but don't use the built-in flash as it will only make for bad backscatter (see Backscatter, Cause and Cure ).
