Educated guess at an empty weight of 1860kg, calculated from SPIFR with other (but similar weight) kit in place of left seat PFD/ND screens & second sticks.
What's a winch & floats? Say 140kg?, plus 200kg for pilots & kit - so 2200 for cash ZFW. 1:30 to 1:45 endurance from arrival at first winch job, if Droopy's calculations are OK'd by CAA!
