If you're not a rivet conter, I'd say that the waterline joint between the upper and lower hulls might be a PITA; in many cases the lower piece "clenches" as it cools so that it winds up being annoyingly narrower than the upper hull. Some have used wooden dowels to spread it back out.
I cut the locating tabs off my deck pieces and sanded the joints true; fit was near perfect.
Otherwise, enjoy the build.
