We just did three days of diving off West Palm and Jupiter. The first day was with Jim Abernethy's boat, and I have nothing but glowing praise for that operation. The crew were enormously helpful, loading all the gear, and providing quick and effective assistance for divers moving to the swim step and climbing the ladder. The boat was immaculate, and accomodated our group (11 divers, I think) quite easily. They'd be my first choice for a dive op, if I were to go back.
The second day, we dove with the Walker boat out of West Palm. They were good people and did a nice job of getting us to the sites, and they were helpful, but the boat isn't laid out as well and was more crowded, and the ladder sucks. (Crawling to my station didn't float MY boat.)
The third day we dove out of Jupiter Dive Center, and I had some significant issues with them. The ramp you use to board and exit the boat is not secured, either at the dock end or on the boat. It has no hand rails. The crew did not help load or unload gear, so we were walking heavy equipment up a steep metal ramp with no way to help stabilize ourselves. The fall was about 10 feet to mud. In addition, the crew while on the boat did not assist divers from their stations to the swim step, or up the ladder and back onto the boat, nor did they relieve divers of things like cameras before reboarding. I wasn't impressed.
