The Tige 20V 2005 vs Tige 21i 2006 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 2006 measures 21,0 feet overall (2006), giving it roughly 19,0 additional feet of deck space compared to the Tige 20V 2005 at 2,0 feet (2005). At 388 lbs and 388 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.
Both boats share a closely matched power ceiling — 380 hp for the Tige 20V 2005 and 380 hp for the Tige 21i 2006. 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. Both carry nearly identical fuel loads — 38 gal and 36 gal — so range won't be a tiebreaker here.
Both boats are rated for 1 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Tige 21i 2006 at 21,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Tige 20V 2005 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
