I've seen the kit in my local shop. It comes with a water/beach base (vac-formed, I assume) that the model sits in. The kit includes a half dozen or so figures and a couple of metal anti-landing obstacles.
As I understand it, the kit skimps on the detail for the rudder and prop, as you won't see them in the base. I think the trumpeter 1/72 kit is more accurate, at least below the waterline...
