How old is the boat? What was it history before you...
If the boat is many, many years old and the boat previously was left in the water over the summer and it hasn't blistered, the likelihood that it will blister now is very low, so I wouldn't barrier coat it at all if that is the case.
That being said, if you want to barrier coat it, do in the off season as you will need to blast/sand away all the paint and you will need to let the bottom full dry of any trapped moisture, else the barrier coat is useless.
So moving forward:
Wake up early on your free Sunday, tape it and wet sand/scotchbrite it and wet rag it to remove the dust. Allow it to dry while you drink a cup of coffee and suit up for painting, paint it, clean-up, have breakfast, drive to the water, launch it and paint the few places that were covered by the trailer during the launch and sail it for the rest of the day. Easy Peasy.
End of Season, get boat. Decide if you want to barrier coat it then.
If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.
