I was fortunate enough to get on the Fling trip this past weekend 4/24/15 - 4/26/15. Signed up Friday afternoon and grabbed one of the last 2 slots.
The ride out was a little bumpy, a few new sailers hadn't prepared and had to use their garbage bags, but by the morning everyone appeared to be feeling great.
Dive breakdown:
1-2 at WFGB #2 75deg, 70' viz, moderate current
3 at HI-389 75deg, 70' viz, high swells / strong current outside the structure
4-5 at EFGB #6 75deg, 70' viz, moderate current
6-7 at Stetson 73deg, 70' viz, least current of the trip
The trip was fantastic. There were hammerheads, a tiger shark (or maybe reef, waiting on picture confirmation), stingrays, morays, silkys, and even mantas. Unfortunately, I did not get to see a hammerhead or manta, but I did witness the supposed tiger shark from a distance. The temperature was very comfortable for me in a full 3mm and hood. The rough seas caused a few issues for a few divers on the trip, but other than that everyone appeared to have a fantastic time, as usual.
