It seems to me that the fastest way to glue the deck to the hull is to tape it up as everyone does, lay the kayak on it's side and glue/tape the inside of the seem (port side for this instance)  Would it be a time safer to then after the inside port seem set and cured is to turn the kayak on the other side so the inside seem of the starboard side be down then of course FG tape it, noticing the now port side is facing upward that I could now FG tape the outside seem of the port side?  It seems the instructions state to tape the inside seems then later the outside.  Again it seems that the outside seem that already has a dried glued seem in the inside can be done at the same time.  I hope this maked sense.
