Nitro 640 LX 2005 vs Nitro Bay 1800 VL 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Nitro 640 LX 2005 or the Nitro Bay 1800 VL 2004?

For trailering, the Nitro Bay 1800 VL 2004 has the edge at 119 lbs dry weight versus 1 092 lbs for the Nitro 640 LX 2005. 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.

Q: Which boat can handle a bigger outboard?

The Nitro Bay 1800 VL 2004 is rated to a maximum of 125 hp, giving it the larger power ceiling. The Nitro 640 LX 2005 tops out at 90 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.

Q: How many people can each boat hold?

The Nitro 640 LX 2005 is Coast Guard rated for 4 passengers, while the Nitro Bay 1800 VL 2004 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.

Q: Which boat is wider, and does it affect trailering?

The Nitro Bay 1800 VL 2004 measures 85" wide, compared to 84" for the Nitro 640 LX 2005. 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.

Q: Which boat has the larger fuel tank — the Nitro 640 LX 2005 or the Nitro Bay 1800 VL 2004?

The Nitro Bay 1800 VL 2004 has the bigger tank at 36 gallons, versus 24 gallons on the Nitro 640 LX 2005. That 12-gallon difference translates to roughly 36–60 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Nitro 640 LX 2005 and Nitro Bay 1800 VL 2004 from the same manufacturer?

Yes — both the Nitro 640 LX 2005 and the Nitro Bay 1800 VL 2004 are built by Nitro. 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.

Detailed Evaluation & Buyer Recommendation

Nitro 640 LX 2005 vs Nitro Bay 1800 VL 2004 — Same Brand, Different Boat

The Nitro 640 LX 2005 vs Nitro Bay 1800 VL 2004 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.

The power gap is worth calling out. Rated to 125 hp, the Nitro Bay 1800 VL 2004 has a 35-hp advantage over the Nitro 640 LX 2005's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Nitro Bay 1800 VL 2004 carries 36 gallons versus 24 gallons in the Nitro 640 LX 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Nitro Bay 1800 VL 2004 is rated for 5 passengers, while the Nitro 640 LX 2005 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nitro Bay 1800 VL 2004 could be the deciding factor.

Bottom line: Choose the Nitro Bay 1800 VL 2004 if your priority is putting more people on the water — it handles 5 passengers and at 0,0 ft it has the deck room to back that rating up comfortably. The Nitro 640 LX 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
