Maybe but not necessarily, you be surprised how many commercial kits provide a plan to build a stand but not the stand or material to construct one and some no stand plan at all!
Looking at the 'kit' the stand the boat's photographed on is similar but its not clear enough to make out if its the same as pictured above.
Still it don't explain that white mark on the stern of hull though which was my original though of it actually being sold on ebay, I could be wrong but to many things odd about this as it is so I'm sticking with my previous bet, same boat, until proven otherwise.
