Speed to not break through ice on wheeler?

[Fishaholic2011]

I realize that if the ice is thin enough speed wont matter.There must be an optimum speed with 1 person on a 4 wheeler to lessen the likelyhood of going through if you were to hit some thin ice.

The speed varies with depth - Here is something I cut an pasted from teh Us Corps of Engineers

A load deflects the ice slightly into a bowl shape. When you drive on floating ice, this moving bowl generates waves in the water. If the speed of the waves equals the vehicle speed, the ice-sheet deflection is increased and the ice is much more likely to break. The problem is more serious for thin ice and shallow water. In general you avoid this danger by driving below 15 mph.
