Looking at a little señera meter sailing cruiser that has the chain plates bolted to the outside of the hull,hopefully the rest of the boat has the same standard of simplicity?

My 2014 Bavaria Cruiser 37 has the chain plates bolted to the outside of the hull - but they're covered with a GRP panel.

EDIT: here's a pic showing the GRP trim panel.

There are some considerable merits in that approach - including no penetrations through the deck, a lesser likelihood of crevice corrosion, ease of inspection, and ease of replacement should corrosion be suspected.

Exactly! However, the "ease of inspection" doesn't apply to my Bavaria. I had some rusty stain marks on the hull from the bottom of the GRP trim panel, and I suspected that there was insufficient drainage in the cavity covered by the trim panel. My first attempt to inspect the area was unsuccessful, there was no way the trim panel was going to be removed without destroying it. So I ordered a new trim panel from Germany and proceeded to remove the old trim panel by chopping it up with a multitool. Once removed, it was obvious why it was difficult to remove - it had been attached with a very generous amount of a Sikaflex-type glue. Inside, there was no obvious rusting of the chainplate or fixings. I modified the lower edge of the new trim panel to ensure it had better drainage, and attached it with OB1, although I had to rig up a weighted lever to apply just the right pressure to hold the panel in until the OB1 set.

Traditionally rigging was brought down to chain plates bolted thru from the outside,great for grinding grp topsides?
My Stella's chainplates were bolted to the hull; but they were on the inside & the heads of the bolts were flush with the outside.The chain plates were carefully packed to timber, cut to fit to the clinker planks so they effectively sat on a flat surface internally. All neat & tidy.

Yes indeed there are many ways to do it on the boat I am viewing it has neat stainless chain plates with thee bolts neatly spaced ,certainly not a bodge?
