aisdb.wsa.wetted_surface_area(tracks)

regression of Denny-Mumford WSA formula using ship type

Parameters:

tracks (aisdb.webdata.marinetraffic.vessel_info()) – track generator with vessel_info appended

Yields:

track dicts with submerged surface area in square meters appended to key ‘submerged_hull_m^2’
