G3 Boats Bay 18 GX 2021 vs G3 Boats Outfitter V187 T 2022 — Same Brand, Different Boat

The G3 Boats Bay 18 GX 2021 vs G3 Boats Outfitter V187 T 2022 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 — G3 Boats Bay 18 GX 2021 at 18,1 ft versus G3 Boats Outfitter V187 T 2022 at 18,7 ft. Weight tells a clearer story for trailering families: the G3 Boats Bay 18 GX 2021 tips the scales at 1 350 lbs — 380 lbs more than the G3 Boats Outfitter V187 T 2022 at 970 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 115 hp, the G3 Boats Bay 18 GX 2021 has a 45-hp advantage over the G3 Boats Outfitter V187 T 2022's 70-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the G3 Boats Outfitter V187 T 2022 carries 19 gallons versus 3 gallons in the G3 Boats Bay 18 GX 2021. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: Performance buyers should lean toward the G3 Boats Bay 18 GX 2021 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the G3 Boats Outfitter V187 T 2022 with its 70-hp rating is the more economical daily driver.

The G3 Boats Outfitter V187 T 2022 is the longer of the two at 18,7 feet overall. The G3 Boats Bay 18 GX 2021 comes in at 18,1 feet, making it roughly 0,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the G3 Boats Bay 18 GX 2021 or the G3 Boats Outfitter V187 T 2022?
For trailering, the G3 Boats Outfitter V187 T 2022 has the edge at 970 lbs dry weight versus 1 350 lbs for the G3 Boats Bay 18 GX 2021. 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 G3 Boats Bay 18 GX 2021 is rated to a maximum of 115 hp, giving it the larger power ceiling. The G3 Boats Outfitter V187 T 2022 tops out at 70 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.
How many people can each boat hold?
The G3 Boats Bay 18 GX 2021 is Coast Guard rated for 5 passengers, while the G3 Boats Outfitter V187 T 2022 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The G3 Boats Bay 18 GX 2021 measures 115" wide, compared to 97" for the G3 Boats Outfitter V187 T 2022. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

The G3 Boats Outfitter V187 T 2022 has the bigger tank at 19 gallons, versus 3 gallons on the G3 Boats Bay 18 GX 2021. That 16-gallon difference translates to roughly 48–80 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the G3 Boats Bay 18 GX 2021 and G3 Boats Outfitter V187 T 2022 from the same manufacturer?
Yes — both the G3 Boats Bay 18 GX 2021 and the G3 Boats Outfitter V187 T 2022 are built by G3 Boats. 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.
