found boat - FC

i loaned a boat to a buddy and was sent back a boat that wasn’t mine! the boat is either a yak or llama, is blue, has aftermarket lash points glued to the floor, a red oral inflation valve for the main boat, no deck and looks otherwise in good (but used) condition. the letters FC are near the valve on a small white spot. Is this anyones? In addition i’m missing my boat, an undecked yak with a repair job on the front left side. the main tube had a 6 inch vertical gash that the folks at alpacka repaired. other than this the boat, at least when i sent it in - was only lightly used, though i’m not sure how hammered it got by my buddy.
