is there a way to identify this mast, or determine it's bend characteristics?
A 2005 XJ that I sail against at Lake Lanier has a Riba mast. There is actually a Riba sticker under the clear-coat near where you feed in the sail. It is difficult to see. If Bimare was using Riba masts in 96 you might look for a similar sticker under the clear-coat to help ID the mast.
