am I completely missing something, I thought Eric's boat that he detailed the building of was an 18' scaup.
		
		
	 
Eric's boat was 16 foot I believe. I know there was a guy building a 21' out of aluninum, and I thought there was someone making an 18 footer out of wood...or there was a member who knew a guy...or something like that...

Eric's was the original 16, the Eric B aluminum 21 is a scaled up of that design.  The new 18 (which I haven't seen the plans or one built) has a number of features that the rest of the duckboats don't - it is a self bailer and it has some sort of integrated longitudinal boxes that serve some sort of structural function.  The new 18 is a much more massive boat.
