Speaking as a member of the Stuck under Bursledon Bridge Club, understimating your air draft can be rather unfortunate, especially on a rising tide.

You should understand a vessel's listed 'air draft' in the context of a bridge's - or a suspended powercable's - safe overhead clearance ( or 'air draft' ). This latter is depicted on marine charts - see your national authority's publication of IHO Symbols as adopted in 1982 and amended subsequently.
Small vessels are too frequently hazarded, in many river estuaries, by overslung power cables 'sagging' - sometimes with fatal results.
