The Tige 20i 2006 vs Tige 22i 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.
On paper these two are close siblings in the size department - Tige 20i 2006 at 20,0 ft versus Tige 22i 2007 at 21,0 ft. Weight tells a clearer story for trailering families: the Tige 22i 2007 tips the scales at 3 895 lbs - 427 lbs less than the Tige 20i 2006 at 3 468 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 - 380 hp for the Tige 20i 2006 and 400 hp for the Tige 22i 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 22i 2007 carries 47 gallons versus 30 gallons in the Tige 20i 2006. 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 22i 2007 is rated for 10 passengers, while the Tige 20i 2006 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Tige 22i 2007 could be the deciding factor.
Bottom line: Choose the Tige 22i 2007 if your priority is putting more people on the water - it handles 10 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Tige 20i 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
