Hi I am new to this site, however, both ALLIGATOR & CROCODILE are listed in a book written by Bill Hannan, ex Shipping Master Devonpot, entitled Fifty Years of Naval Tugs - ISBN 0-907771-25-4. It adds nothing to the date of ALLIGATOR's loss other than being based in Ceylon under C in C East Indies. It states, however, that CROCODILE was wrecked on the SW Coast of India on 03.05.46 and was salvaged and sold out of service in January 1947. They were 116' 9" Long x 26' 6" Beam x 13' draught at 395 tons Displacement. Coal fired, Steam Triple Expansion 1000IHP, Twin Screw, Speed 12kts Hope this is of some help.
