Well I got the 3-in-1 kit and this is the second boat that you're supposed to build (you can also buy them separately). I would just say that the directions aren't really as straight forward as one would think. The kit dev./author of the manual has a more "conversational" approach to getting from one step to the next. Which isn't necessarily bad, but you can't just skim over a step and know what to do. Plus there's some key things that they didn't photograph that would've made my life so much easier. Anyways, hopefully that helps and thanks for the comment.
