What type of ship is SEA PORPOISE?+
SEA PORPOISE is classified as a dredger vessel registered under the TT flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full dredger fleet at /vessel-type/military-special and full TT flag list at /flag/tt.
