The Tige 21i 2007 vs Tige Switch i 2005 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 Switch i 2005 at 2,0 feet (2005). At 388 lbs and 337 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 400 hp, the Tige 21i 2007 has a 60-hp advantage over the Tige Switch i 2005's 340-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 21i 2007 carries 36 gallons versus 3 gallons in the Tige Switch i 2005. 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 Switch i 2005 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 Switch i 2005 could be the deciding factor.
Bottom line: Choose the Tige Switch i 2005 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.
