Try this course for Moorings briefing....

Its not a bad course. If you have been in the last year to a briefing or are a regular there they let you skip the briefing. I will ask regardless if there is anything new that I need to know. The one thing I always like to have every time is the boat review. I think this is what will hold you up at 600 pm on any night and it is "controlled chaos" in the AM at Moorings base as everyone is trying to depart..

I believe Riteway/C&C closes at 700? so you may want to have your boat pre provisioned.

IMHO I would get an earlier ferry back to STT as with what you have you will have less than 2 hours at STT airport departing. You have to have the boat back by 1000 anyways and it can be kind of crowded in Road Harbor around 10:00 with boats returning so we try to get back to base by 0800.

Have a great time
