I've seen more than one row boat pictured in various model exhibits. No idea if they were kits, or not, but sort of doubt it. If you wouldn't mind scratch building an R/C row boat there is at least one "toy" one available commercially. Buying one, tearing it apart to see how it's 'done', would at least give you some idea of how to go about building one. (Saw a 'toy' one advertised in some catalogue, couldn't stand it so got one. Found out real quick that I'm not much of a scratch builder, so didn't copy it. I'm sure it's possible though.) Good luck!
