Look at it this way, a 1/25 scale figure would be less than three inches tall (as samll as two and a half), much smaller than than a 5 inch tall action figure that would fit in the Kenner Batskiboat. Even taking into account that vehicles made for action figures are usually made smaller than they should be to be properly in scale, that Kenner Batskiboat would still be much larger than the model kit. The Kenner one could be considered as large as 1/12th scale.
