The Tige 20i 2007 vs Tige 21i 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 Tige 21i 2007 measures 21,0 feet overall (2007), giving it roughly 19,0 additional feet of deck space compared to the Tige 20i 2007 at 2,0 feet (2007). Weight tells a clearer story for trailering families: the Tige 20i 2007 tips the scales at 3 468 lbs — 3 080 lbs more than the Tige 21i 2007 at 388 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.
Both boats share a closely matched power ceiling — 400 hp for the Tige 20i 2007 and 400 hp for the Tige 21i 2007. 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. Fuel capacity breaks the other way: the Tige 21i 2007 carries 36 gallons versus 3 gallons in the Tige 20i 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 Tige 20i 2007 is rated for 8 passengers, while the Tige 21i 2007 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Tige 20i 2007 could be the deciding factor.
Bottom line: Choose the Tige 20i 2007 if your priority is putting more people on the water — it handles 8 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Tige 21i 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
