Tracker Avalanche SC 2003 vs Tracker Tundra 21 WT 2007 - Boat Spec Comparison

Q: Which is easier to trailer — the Tracker Avalanche SC 2003 or the Tracker Tundra 21 WT 2007?

For trailering, the Tracker Avalanche SC 2003 has the edge at 137 lbs dry weight versus 1 965 lbs for the Tracker Tundra 21 WT 2007. 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 Tracker Tundra 21 WT 2007 is rated to a maximum of 275 hp, giving it the larger power ceiling. The Tracker Avalanche SC 2003 tops out at 175 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 Tracker Avalanche SC 2003 is Coast Guard rated for 5 passengers, while the Tracker Tundra 21 WT 2007 is certified for 7. 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: Do these boats require an oversize trailer permit to tow on US highways?

Both the Tracker Avalanche SC 2003 and Tracker Tundra 21 WT 2007 share an 96 in 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.

Q: Which boat has the larger fuel tank — the Tracker Avalanche SC 2003 or the Tracker Tundra 21 WT 2007?

The Tracker Avalanche SC 2003 has the bigger tank at 41 gallons, versus 6 gallons on the Tracker Tundra 21 WT 2007. That 35-gallon difference translates to roughly 105–175 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Tracker Avalanche SC 2003 and Tracker Tundra 21 WT 2007 from the same manufacturer?

Yes — both the Tracker Avalanche SC 2003 and the Tracker Tundra 21 WT 2007 are built by Tracker. 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

Tracker Avalanche SC 2003 vs Tracker Tundra 21 WT 2007 — Same Brand, Different Boat

The Tracker Avalanche SC 2003 vs Tracker Tundra 21 WT 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.

The power gap is worth calling out. Rated to 275 hp, the Tracker Tundra 21 WT 2007 has a 100-hp advantage over the Tracker Avalanche SC 2003's 175-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Tracker Avalanche SC 2003 carries 41 gallons versus 6 gallons in the Tracker Tundra 21 WT 2007. 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 Tracker Tundra 21 WT 2007 is rated for 7 passengers, while the Tracker Avalanche SC 2003 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Tracker Tundra 21 WT 2007 could be the deciding factor.

Bottom line: Choose the Tracker Tundra 21 WT 2007 if your priority is putting more people on the water — it handles 7 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Tracker Avalanche SC 2003 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
