Glastron GT 185 2008 vs Glastron GT 185 Bowrider 2007 — Same Brand, Different Boat

The Glastron GT 185 2008 vs Glastron GT 185 Bowrider 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Glastron GT 185 2008 at 18,0 ft versus Glastron GT 185 Bowrider 2007 at 18,0 ft. At 2 315 lbs and 2 315 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 190 hp, the Glastron GT 185 2008 has a 55-hp advantage over the Glastron GT 185 Bowrider 2007's 135-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 23 gal and 23 gal — so range won't be a tiebreaker here.

At this size, power-to-weight ratio matters more than outright horsepower. The Glastron GT 185 2008 comes in at 12 lbs per hp versus 17 lbs per hp for the Glastron GT 185 Bowrider 2007. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Performance buyers should lean toward the Glastron GT 185 2008 and its 190-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Glastron GT 185 Bowrider 2007 with its 135-hp rating is the more economical daily driver.

Glastron GT 185 2008 vs Glastron GT 185 Bowrider 2007 — Common Questions

Which is the larger boat — the Glastron GT 185 2008 or the Glastron GT 185 Bowrider 2007?
The Glastron GT 185 Bowrider 2007 is the longer of the two at 18,0 feet overall. The Glastron GT 185 2008 comes in at 18,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Glastron GT 185 2008 or the Glastron GT 185 Bowrider 2007?
For trailering, the Glastron GT 185 Bowrider 2007 has the edge at 2 315 lbs dry weight versus 2 315 lbs for the Glastron GT 185 2008. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Glastron GT 185 2008 is rated to a maximum of 190 hp, giving it the larger power ceiling. The Glastron GT 185 Bowrider 2007 tops out at 135 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
Which boat has the better power-to-weight ratio?
The Glastron GT 185 2008 has a better power-to-weight ratio at 12 lbs per hp compared to 17 lbs per hp for the Glastron GT 185 Bowrider 2007. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Glastron GT 185 2008 and Glastron GT 185 Bowrider 2007 share an 88 in. (2.24 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Glastron GT 185 2008 and Glastron GT 185 Bowrider 2007?
Both boats carry similar fuel loads — 23 gallons and 23 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Glastron GT 185 2008 and Glastron GT 185 Bowrider 2007 from the same manufacturer?
Yes — both the Glastron GT 185 2008 and the Glastron GT 185 Bowrider 2007 are built by Glastron. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
