The odds are not that bad for forced landings.

I would rather make a flare at Vref 40 according to the flight manual parallel to the swell and dissipate the remaining energy in the flare. The ocean runway is usually large in every direction so wind direction is of not much concern. If you fly in close to stall speed you might stall prematurely. Without working donkeys often you have lost most of the hydraulics. That the success rate of glider pilots on forced landings is high, should not be a surprise.
