Measuring air draft

Tomorrow we hope to head across to the Gulf coast through the Okeechobee Waterway but there is the small matter of a railway bridge with a open height of 49 feet in the way ten miles west of Indiantown. Fellow Westsailers, Dick and Libby have gone under the bridge several times but my mast is not original so I had to check it's height.
It turns out that my mast is 44 feet high from the deck to about a foot above the top to allow for the tricolour and the VHF antenna.

Checking the height of the mast step above the water is a bit of a challenge too. We laid a pole horizontally on the deck and measured each end above the waterline and averaged them. Bottom line is that our air draft is a little bit over 48 feet so in theory we should be able to get under the bridge. Wahoo!
