Both the Tige 22i 2009 and the Tige Z1 2008 are modified-V designs, both built in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department - Tige 22i 2009 at 21,0 ft versus Tige Z1 2008 at 21,0 ft. Weight tells a clearer story for trailering families: the Tige 22i 2009 tips the scales at 3 895 lbs - 181 lbs more than the Tige Z1 2008 at 3 714 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 400 hp, the Tige 22i 2009 has a 40-hp advantage over the Tige Z1 2008's 360-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Tige 22i 2009 carries 47 gallons versus 38 gallons in the Tige Z1 2008. 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 2009 is rated for 10 passengers, while the Tige Z1 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Tige 22i 2009 could be the deciding factor.
Bottom line: Choose the Tige 22i 2009 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 Z1 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
