Overview
The 2009 GS 259 gets redefined for 2009. This on the water getaway is one of their twin cabin models with runabout performance and a family-friendly design. Glastron’s intent was to deliver a balance of more value, more comfort and more performance than expected. The builder takes advantage of every bit of space and still delivers over 41 mph with a MerCruiser 5.0L engine. There is 72” of headroom below, which is remarkable for this size of boat. Below you have all the basic comforts you may want for a night on the hook with the family, especially if you get the air conditioning option with a generator.

Speeds measured with Stalker ProSports radar gun. Fuel consumption (gallons per hour) measured with Floscan digital fuel-flow meter on gas inboards, sterndrives, and outboards, TechMate electronic scan tool on gas EFI inboards, Caterpillar digital fuel-flow meter on diesel engines, or permanently installed fuel-monitoring equipment. Range is based on 90% of published fuel capacity. Sound levels determined using Radio Shack digital decibel meter on A scale. 68 dBA is the level of normal conversation.
