I already bought the RAM mount to mount to my steering rail/guard. Here is the plan I have. I have two ipads on the boat and one macbook pro. I have a Dual bluetooth GPS receiver and am running mac enc on my macbook pro in the nav station (i haven't picked the charting program for the ipads yet). There are a couple of programs that interface with mac enc. Anyhow, my current plan is to run the ipad/macbook pro navigation setup next to my current 10" chartplotter on our next bahamas trip and see which I like better, I'm pretty sure I know the answer already LOL.
Once all that it done I plan to, tie it in so I can run my music from the cockpit and even stream a movie from my macbook pro to one of the iPads. We have an 26 hour run each way so it's nice to have various forms of entertainment.
