Matt Allen bought Shogun V in mid-2015 and renamed her Ichi Ban. After a new keel fin and mast were added, she raced for the first time in the 2015 Sydney Gold Coaster, minus Allen, who was competing in the Transpac Race and Gordon Maguire skippered her to 12^th overall. Allen returned to dominate Division 1 at 2015 Airlie Beach Race Week, then ran second in Division A to the new Beau Geste at the Australian IRC Championship. Ichi Ban won every race in Division 1 at the 2016 Sydney Harbour Regatta, repeating that result to claim the 2016 NSW IRC Championship.

Further mods for offshore racing and Ichi Ban notably won the 2016 Sydney Gold Coast race by nearly six hours. Beau Geste beat Ichi Ban to the punch again for Division 1 of the 2016 Australian IRC Championship before she finished the Flinders Islet Race second overall. After finishing second overall in the Bird Island Race, Ichi Ban is second in the BWPS, four points behind Chinese Whisper. This is the TP52 to beat, should the President of Australian Sailing take this boat and not his Carkeek 60 of the same name.
