The Smoker Craft 171 Pro Bass 2013 vs Smoker Craft S-8521 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.
Size is the most obvious dividing line here. The Smoker Craft S-8521 2007 measures 21,0 feet overall (2007), giving it roughly 3,2 additional feet of deck space compared to the Smoker Craft 171 Pro Bass 2013 at 17,8 feet (2013). Weight tells a clearer story for trailering families: the Smoker Craft 171 Pro Bass 2013 tips the scales at 1 075 lbs — 880 lbs more than the Smoker Craft S-8521 2007 at 195 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 125 hp, the Smoker Craft S-8521 2007 has a 35-hp advantage over the Smoker Craft 171 Pro Bass 2013's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 21 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 2007 is rated for 12 passengers, while the Smoker Craft 171 Pro Bass 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Smoker Craft S-8521 2007 could be the deciding factor.
Bottom line: Choose the Smoker Craft S-8521 2007 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 171 Pro Bass 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
