The Sundance 171 Bay 2006 vs Sundance B22 CX 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.
Size is the most obvious dividing line here. The Sundance B22 CX 2006 measures 21,0 feet overall (2006), giving it roughly 4,0 additional feet of deck space compared to the Sundance 171 Bay 2006 at 17,0 feet (2006). Weight tells a clearer story for trailering families: the Sundance B22 CX 2006 tips the scales at 1 745 lbs - 255 lbs less than the Sundance 171 Bay 2006 at 1 490 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 150 hp, the Sundance B22 CX 2006 has a 60-hp advantage over the Sundance 171 Bay 2006'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 - 34 gal and 33 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sundance B22 CX 2006 is rated for 14 passengers, while the Sundance 171 Bay 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sundance B22 CX 2006 could be the deciding factor.
Bottom line: Choose the Sundance B22 CX 2006 if your priority is putting more people on the water - it handles 14 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Sundance 171 Bay 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
