| Totals | 26 ships, 79,456 tons. 6 were small vessels often not included in sinkings, amd not credited to Seawolf in JANAC. Also not credited to Seawolf was a midget submarine, lost when the vessel towing it (Yamazuru Maru) was sunk. Seawolf shared credit with USS Whale in the sinking of Tarushima Maru. JANAC - 18 ships, 71,609 tons, plus shared credit with USS Whale for sinking Tarushima Maru. Note that the criteria JANAC used included all Japanese Naval vessels (although JANAC did not usually count warships less than 500 tons that were converted from merchant ships) and all Japanese merchant vessels of 500 or more gross tons known or believed to have been lost during the war. Differences between JANAC figures and current research are noted above. Alden-McDonald credit Seawolf with 26 ships and 79,456 tons sunk, including shared credit with USS Whale in the sinking of Tarushima Maru. SORG credits Seawolf with 25 ships and 109,600 tons sunk, including a sampan of unknown tonnage.. Wrecksite credits Seawolf with ships and tons sunk. |
