When two boats share the same hull type — in this case both the Tige 20i 2013 and the Tige Z3 2013 are modified vee designs with fiberglass construction — 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?
Size is the most obvious dividing line here. The Tige Z3 2013 measures 23,0 feet overall (2013), giving it roughly 21,0 additional feet of deck space compared to the Tige 20i 2013 at 2,0 feet (2013). Weight tells a clearer story for trailering families: the Tige 20i 2013 tips the scales at 3 268 lbs — 2 804 lbs more than the Tige Z3 2013 at 464 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.
For family outings this is probably the sharpest distinction between the two. The Tige Z3 2013 is rated for 16 passengers, while the Tige 20i 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Tige Z3 2013 could be the deciding factor.
Bottom line: Choose the Tige Z3 2013 if your priority is putting more people on the water — it handles 16 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Tige 20i 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
