Now...on to the trip report. I will have lots to say, so it will be posted in segments as I have time

These are just basics. Let me know what else you're curious about and I'll be happy to expound...
First let me say that the liveaboard lifestyle is a great way to experience LOTS of diving in an effortless way. I was privileged to be a part of Stephen Frink's group and had a great time watching him practice his art.
My trip report is based solely on this week.
The way it worked aboard the Aggressor during our week:
Upon boarding, you enter past the dive deck, so it's a simple to task to stop there and unpack your dive gear before proceeding to your cabin. The dive deck had plenty of space. Each diver has their own spacious tank area with storage beneath. Wetsuits are placed on hangers around the perimeter of the deck. I selected my spot, dropped off my dive gear and never moved it again for the week. After each dive, we would simply remove the regulator from the tank and within 15 minutes we had a fresh fill of nitrox, and fills were always plentiful.
Dives were GENERALLY at 8, 10, 2, 4 and night dive at 7:30 after dinner. On a couple of days during our travels to/from Cayos Cochinos or Utila, the schedule was shifted so that we had a quick continental breakfast and started our first dive at 7. This was always followed by hot breakfast after dive completion. Every single dive day (Sunday thru Thursday) we had the opportunity to complete 4 daytime dives plus a night dive. On Friday (final day) we did two morning dives before returning to port.
All dives are done from the mother ship. A zodiac is towed behind in case it is needed.
Even with a boat the size of the Aggressor, we were able to perform several drift dives. We had a good group of divers, all of whom somehow managed to follow instructions

Drift dives were well organized. All divers assembled on the dive deck as the divemasters gave us a countdown. Three minutes...two minutes...one minute...DIVE, DIVE, DIVE! At that point, we all performed a giant stride entry and fell into formation with one divemaster (instructor level) leading the group and one "shepherd" bringing up the rear. With our group, dives were over an hour. We would all surface together and the yacht would ease alongside us with a trail line for every diver to grab. The captain was operating the controls from the deck and making sure all was well. Once all divers were on the line, we would climb up two by two...there was a nice ladder on each side of the dive deck.
On all moored boat dives, each diver had the option to either follow the divemaster or dive their own plan. Obviously, there were numerous photographers on board, so they had options. Due to their local knowledge, most divers chose to follow the guides. No matter how good you think you are at spotting critters, it almost always beneficial to follow someone who is intimate with the local facts.
Obviously, due to the size of the vessel, they are not able to moor at any dive site they wish. They have select moorings to accommodate them and I'm told they plan to add more as time progresses.
Mr. Frink was very proactive with dive site selection and itinerary. During our week aboard the Aggressor, he made the decisions about site selections based on the input of his group. Captain Nestor was very accommodating and sampled numerous different dive sites in a quest for decent visibility, which proved elusive during our week of diving. I am the "brighter side" person...I try to make the most of every opportunity. When the viz sucks, I just get closer to the reef and focus on the beauty of the structure and the small things that reside within it...one of my favorite things about Roatan
Thankfully, I managed to achieve 4 dives per day, or I probably would have gained 10 pounds! I'm not sure what I was expecting in terms of food, but all of the meals served on board were unbelievably good. I did not hear any complaints about anyone going hungry. For our last dinner, we were served Filet Mignon and Lobster! No problem with the food for sure
Friday night is spent at the dock at Romeo's Restaurant to allow for re-provisioning of the ship for the next journey. This is the only meal not included in the fare. We all dined together ashore at Romeo's. Romeo surprised Steve by pulling down a framed copy of an article he had written for Skin Diver Magazine in 1987 about the Caribbean Aggressor boats. Good times were had by all
That's it for the initial trip report. Again, please let me know if you have specific questions. I have zillions of pictures and videos.
