Also found this:
"Landing on water: Over the years, there has been an on-going debate on
whether
it is better to land gear up or gear down on water. Current thought from
Tom Knauff
is to always land gear down. The rationale is that a water landing with
gear up will
result in the tail touching down first with the tail being sucked into
the water. This in
turn results in the nose pitching up and a higher angle of attack for
the wings. Given
the higher angle of attack, the glider then shoots back into the air
until it stalls. Upon
stalling, the nose drops down and dives steeply into the water. Put the
gear down in
a water landing and try to keep the tail from dropping. Dropping the
gear also results
in increasing water resistance, which further slows down the ship.
Another water l
anding aspect Tom relayed is that one always wants to land close to and
parallel to
the shoreline, but not so close as to hit the bottom in the event
something goes
wrong during the landing. You will want to maintain good aileron control
for as long as
possible. You do not want one of the wing tips hitting the water first
at a high speed
as the glider may flip. Once the glider has settled to a stop, it may
float for awhile.
I once saw a PIK that had been taken off the bottom of a lake and restored.
This one flew better than it floated. "

Hmmm, it is also said that the gear should be deployed. I understand
this is the recommended procedure in Finland. This glider certainly
did not lower his gear.

Hi Alan
Precisely!
A major reason for posting this link was to through doubt on the
claim that gliders always submarine on water landings.
Kind regards to all

Thanks Bernard,
I hope we don't see a spate of such landings now. But to me it
was useful because a fear for all would be the nose digging in
leaving the cockpit under water. Options were oft discussed in
Finland in 1976.
I think it also implies such landings should be done with the
undercarriage up. Not an option to things like Pipers and
Cessna's. Perhaps options are discussed in manuals or some study
somewhere.
Thanks and I hope I never have to get that wet.

Hello all
It appears to me that this glider pilot either left his field
selection a little late or he wanted to
imitate Captain Sullenberger! In any case, it was well done!
