Deck-only chainplates

[mrx]

Good time-of-the-day!

I am currently considering buying a boat and have a concern I'd really like to discuss with more experienced boat people

The boat is Contest 33, 30something years old.

It appears that the chainplates on this boat are only connected to the deck. There are 3 sets of shrouds wach side (at angles forward and back and one going straight), all connected to loops in the deck. As far as see, those loops are held to some sort of a backing plate embedded in fiberglass under the deck. This is all. No connection to main bulkhead, nothing goes to the hull.

I got into a brief conversation with designers of the yacht (or, rather, people that took over - original designer passed long time ago) and they say that this is not an unusual design.

Still, I'd like a bit more guidance on this - this is one issue I am not sure I entirely understand the implications of.

So, how common is this? What are the things to consider?

Any help would be appreciated!
