I rebed my stanchions 2 years ago using the Mainsail method. you can reach all the nuts by taking off the little piece of trim under each one that is attached to the liner. The chain plate come through the deck and turns into a rod the attached at the seat at the bulkhead next to the sink and the icebox. i have not done the chain plates yet. The stanchions at the bow and the stern are a little more trouble but can still be reached. no need to cut any fiberglass.
