Smoker Craft Millentia 172 2004 vs Smoker Craft S-8521 2006 — Same Brand, Different Boat

The Smoker Craft Millentia 172 2004 vs Smoker Craft S-8521 2006 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.

Both boats share a closely matched power ceiling — 125 hp for the Smoker Craft Millentia 172 2004 and 125 hp for the Smoker Craft S-8521 2006. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 24 gal and 24 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Smoker Craft S-8521 2006 is rated for 12 passengers, while the Smoker Craft Millentia 172 2004 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Smoker Craft S-8521 2006 could be the deciding factor.

Bottom line: Choose the Smoker Craft S-8521 2006 if your priority is putting more people on the water — it handles 12 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Smoker Craft Millentia 172 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Smoker Craft Millentia 172 2004 vs Smoker Craft S-8521 2006 — Common Questions

Which is easier to trailer — the Smoker Craft Millentia 172 2004 or the Smoker Craft S-8521 2006?
For trailering, the Smoker Craft Millentia 172 2004 has the edge at 126 lbs dry weight versus 195 lbs for the Smoker Craft S-8521 2006. 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.
How many people can each boat hold?
The Smoker Craft Millentia 172 2004 is Coast Guard rated for 5 passengers, while the Smoker Craft S-8521 2006 is certified for 12. 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 Smoker Craft S-8521 2006 measures 102" wide, compared to 91" for the Smoker Craft Millentia 172 2004. 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.
How do the fuel tanks compare on the Smoker Craft Millentia 172 2004 and Smoker Craft S-8521 2006?
Both boats carry similar fuel loads — 24 gallons and 24 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Smoker Craft Millentia 172 2004 and Smoker Craft S-8521 2006 from the same manufacturer?
Yes — both the Smoker Craft Millentia 172 2004 and the Smoker Craft S-8521 2006 are built by Smoker Craft. 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.
