In the forces (Royal Navy) we aimed to have1 to 6 hours expected survival time in 10 degree water. Age, fitness and underlying health conditions being the major factor.
If anyone is still in the water, it is likely they are dead.
A) Swimmer
Or
B) RIB (rigid inflatable)
In the water by 6 minutes with a man overboard scenario.
