Embrittlement in all the tangs, solid fasteners, etc. - should be MUCH heavier!!! and better quality metal.
Cranse collar is the attachment for the forestay, whiskerstays, etc. - it''s essentially a cylinder with lugs welded on. Repetetive stress loading makes it behave like a spring - and like springs, the metal gets tired. The correction should be in the shape of the Greek letter "phi" - so that there is a direct stress connection from the forestay to the dolphin striker. Without the direct connection the cranse is subject to a lot of elastic deformation - not good!
Chainplates are mostly boxed-in behind the cabinerty.
