Same in Europe for Schleicher. Our club had to spend a similar amount for putting an otherwise undamaged ASK21 in service, after a lake landing. I guess the days of let-it-dry and rig are finished.
Nobody got hurt in Italy for water landings. Minor concussions for a spin and water crash (glider destroyed).

Schempp policy for water landing is that all pushrods get changed in the gliders, they cannot risk corrosion and resulting ADs 10-20 years later. I once asked factory guy how much this is, answer was that around 20k euros (lots of holes in wings)
