The owner was very accommodating to scheduling the dives we wanted to do with much attention placed on surface intervals and flight schedules. Underwater Diversions has an office in San Juan Capistano, Ca. also and they can arrange all the details of the trip for you. Underwater Diversions is also American owned and it really shows. I heard everything from the divemaster didn't know how to dive and could care less if you drowned, to lousy dive sites picked, and poor condition of rental gear. U.D. with out a doubt has the nicest dive boat in the harbor.
Many operators have pongas, which are wooden boats with outboard motors.
The pongas usually have a tarp over them to provide some shade. U.D.'s boat has a head, inside cabin, upper deck with covered seating and a great view. It also has standard tank ranks and gear stowage on the main deck and looked like it was built for diving. The crew was great and even rinsed, dried, and repacked our gear bags each day. M ost shops are comparable in prices but not in service.
