In the July, 2008 edition of "Gliding International", edited by John
Roake, there's this word on water landings:
Walter Schneider and Wolf Lemke of LS fame carried out water landing
test and ditched an LS1 prior to the World Championships in Finland.
They were worried about the lack of land out options and the
proliferation of lakes. They assumed that landing wheel up would be
the preferred option, but discovered that the glider 'bounced' off the
surface and dropped a wing as the fuselage entered the water because
of its shape. They tried it again with the wheel down, deliberately
put the tail down first and discovered that the wheel acted as a
gentle brake and controlled the whole process much better."
