F-35 Pedrick Mast Height Above Waterline

I was wondering if anyone knows the exact mast height above waterline for a F-35 Pedrick design. The overall mast length is 55.7 feet but the mast step appears to be about 12 - 18" below the waterline.

P = 45.3’

Thanks

The Pedrick F-35 has a mast above water height of 54.5 ft. Add your antenna and/or masthead lights to get the total clearance. I have measured this and it is consistent with the published number.

Thanks for the info. 54.5 is about what I estimated.
