Some boat model number reshuffling and LOA changes happened at Chaparral Boats between 2009 and 2010. Since the 2010 model line change, there is only one "pocket cruiser" Signature, it is Signature 270 with LOA 27'00". Since then the pre-2010 Sig 250 became Sig 270. and pre-2010 Sig 280 became Sig 290. The Sig 250 and Sig 280 model numbers are gone after 2009.
