I just bought a 18 foot 1990 Bluewater. Not sure of the model, but it is an open bow with a 5.7 merc I/O. Eagle maybe. The hull is pristene, hardly a scratch, even on the keel. The interior has been converted to more of a fishing boat with pedestal seats and the wiring of accessories leaves something to be desired, but it runs strong and appears to have been well maintained.
