My first trip will be in November so I will let other more experienced divers comment. I thought you should know about the fire that sunk the Red see Aggressor I and resulted in the death of one of the customers. My understanding is that Aggressor is a franchise and so you cannot exactly expect the safety standards of one LOB to be the same of others in the fleet. Just be aware:
The Rescue of 18 tourists and one American is dead in a boat fire in Marsa Alam | Hurghadians Sources : the dead American tourist tried to save her laptop from the fire. | Hurghadians

I havent checked the validity of the postings from the survivors, but it's worth a read.
I also inquired about the event when I tried to book with the Red Sea Aggressor II for my trip, and they declined to comment.
