In 2009 GW replaced the 282 Sailfish with the 290 Chesapeake. The 290 was last offered in 2015. I remember at the time the major reason behind the small incremental change in size was to accommodate a generator, which the Sailfish couldn't fit. I think the 30' Marlin is a lot more boat than the 290 and only a small difference in length...
Very hard to find 07 and 08 Sailfish as the economy crashed and dramatically curtailed production.
