[IC27A] Height of Mast

[Michael]

Hello all,
Does anyone have a ballpark figure for the height of the mast with an average 
weight C27 (average stocked stores, equipment etc.)? I have a couple of bridges 
close by and always look with mild fear as I pass under them. Invaribly, some 
bridge operator will ask what the height of the mast is. I would like to have 
the answer for him/her.
Thanks,
Mike (So. Cal)
