The Pro-Drive X 17 x 54 (21 in. sides) 2007 vs Pro-Drive X 20 x 60 (18in. sides) 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.
For family outings this is probably the sharpest distinction between the two. The Pro-Drive X 20 x 60 (18in. sides) 2007 is rated for 6 passengers, while the Pro-Drive X 17 x 54 (21 in. sides) 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pro-Drive X 20 x 60 (18in. sides) 2007 could be the deciding factor.
Bottom line: Choose the Pro-Drive X 20 x 60 (18in. sides) 2007 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Pro-Drive X 17 x 54 (21 in. sides) 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
