Chaseh's or Dan's posts might be open to interpretation, but it is not all that uncommon for the Utila Aggressor to only dive at just CCV's dive sites all week. Gas has gotten very costly.
I'm sorry but this just isn't true. It is very rare for the Aggressor to stay at or near one dive site for more than a day at most. The only exceptions are weather or guests requests. I've been on this boat and visited 4 different islands, lived in Utila and saw the boat move around the Island, and lived in Roatan and saw the boat move around that Island.
Yes , you can't get off the boat often but then again, you can dive 5 times a day in comfort with almost no effort and visit more dive sites than any land based operation. Yes it cost more but you get more dives, great food and drinks and outstanding service.
