What you're seeing is likely a combination of pre-bend, & induced bend. The former can be done when the spar is built, or at any time in it's life. And the latter is tuneable via the shrouds, stays, deck
blocking, & step position. With the amount o bend varying from boat to boat (design) as well as on how a boat is tuned for prevailing conditions, & so that the spars work well in conjunction with the sails
However there should be a set of measurements available which state what the normal range of bend on this boat's spar are. Available from; the designer/the original plans, owner's associations, tuning guides for the boat, or owner's associations.
