All new for 2009, the GS 289 is an extraordinary twin-cabin cruiser. The largest, most luxurious and most well-appointed twin-cabin model we’ve ever produced—and we’ve really outdone ourselves this time. Above and below deck, the GS 289 attains a new level of refinement for Glastron Sport Cruisers. Luxury, purpose and performance meet to create a totally pleasurable big boat experience. This is sport cruising at its finest.
