Re: Tartan 31 or 28?
What are your goals with the boat? Does seem to be a very specific item to make a choice on a boat. I would venture to guess that most boats have chainplates mounted on the bulkhead. Makes for easy inspection! Biggest issue I see is that if there is leakage, you can wind up with some rotting. As long as this bulkhead is solid and well tabbed, should not be an issue. The one thing I do not like at all is chainplates that are fiber glassed in, they allow no inspection and it creates a perfect place for crevice corrosion. So for me it is best if they are visible for inspection. I also don't like when they are behind lots of cabinetry, easy to forget about them.
