Composite chainplates: The ideal solution for composite hulls Sometimes, old ways of doing things survive simply because "that's how it's always been". From time to time, though, it is useful to look at the old ways to see if, in the context of modern knowledge, they still make sense. If they don't, perhaps they should be changed. In today's article, I'd like to take a look at a key component of many sailing yachts- the chainplate. Current chainplate designs date back to before the Industrial Revolution, and I think they're overdue for a redesign.
