One winter, Nuna logistics had a 14g and 16g cat grader, at each end of Tibbit lake NWT, from excessive speed. both partly sticking out of the ice,
Thus on big lakes, the approach speed to shore is slow, say 10kms an hour, but the may be 60-70kms an hour on open water on a big lake.

Didn't know that.
