Given the boat has no blistering, if you are going to use it in the same manner that it has been used in the prior 19 years (same water, same season length), then I would not bother with barrier-coating (which is 4-5 coats at least).
I would proceed with recommendation 3, be sure to follow the paint prep instructions, including sanding the bottom with 80 grit paper first.
Certified...in several regards...
