erhaps the general solution would be to lower the speed of ALL Allied ships when the weather is bad.

That would be a nice solution! In bad weather conditions all ships reduce speed, due to several reasons: First of all they become more controllable and have more reserve power to make hard maneuvers, second they hit softer against the sea, and third they prevent the risk of over-revving the engine when the screw comes out of the water.

Probably the perfect solution would be to link a progressive percentual reduction in ship speed according to the existing 4 wind states, as that means also sea states. Something like: Windspeed0 and 1 = 100% speed, windspeed 2= 90% speed, and windspeed 3= 70% speed.

This all would also fix the bug you mentioned of convoys keeping speed no matter what weather. In reality, when plotting an intercept the commanders had to guesstimate the speed reduction of convoys when they were affected by bad weather, hence the importance of weather reports and forecast.
