No idea how anyone would be partying so hard @ night during NWF
(well I guess once you've been there - or seen the videos - it gets a bit more logical ??)
Anyway....a "similar" batten will be more functional than no batten or a broken one.
And sailing with a marginal one better than not sailing...
While there's no requirement to replace the batten with a genuine one, the Reflex's are a pretty dialled in sail, built to highest performance with very tight tolerances. Keeping the sail as close to original in terms of shape/twist etc is obviously preferable... Severne does support the order/supply of spare parts for all the race sails as a service item, so the original item could/can be obtained thru the Severne Dealer network if required/desired etc.
