Overview
Glastron has a new
queen of the line
now, the GS 289
Sport Cruiser. This
all-new model is the
largest and most
luxurious twin cabin
boat Glastron has
ever produced,
according to the
company. She has
Alphastone counters,
leatherette
upholstery and more
room than I expected
below. You have
everything you need
for a weekend aboard,
away from the hustle
and noise of your
neighborhood.
Performance? Well,
how about just under
42 mph with a 300-hp
Volvo 5.7?
Considering this
boat weighs 6500lbs
before you add gas,
water, ice and
goodies, it has the
power and the
performance. Topside
she has lots of
stainless steel
where others might
try to save using
plastic. Snap-in
carpet keeps the
deck looking snappy
and the wet bar has
a standard
refrigerator to keep
the snacks and cold
drinks ready.
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.
