Don't know how Kim measured his but I taped the bottom third of a long dowel to
the main halyard, attached a 100 foot tape to the top of the dowel and hoisted
it so the tape, when viewed from down the pier, was even with the points I
wanted to measure; mast head, windex, wind instrument, antenna, etc.
I lowered the tape to the waterline. That should be an inch or so longer than
the actual height if swung to the vessel's centerline, i.e., my safety factor.
As for transiting bridges, some bridges have more clearance 1 or 2 openings
left or right of the marked channel. The center opening(s) often have a deep
steel girder due to the wider span. The other openings may have shorter
concrete spans. If there is adequate depth, the adventurous sailboat owner may
pass through one of the side openings.
I've heard of boaters using golf rangefinders to estimate vertical clearance.
If so, they are at the mercy of the accuracy of the device.
