When two boats share the same hull type — in this case both the Tige RZ4 2012 and the Tige Z1 2012 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?
On paper these two are close siblings in the size department — Tige RZ4 2012 at 24,0 ft versus Tige Z1 2012 at 21,0 ft. Weight tells a clearer story for trailering families: the Tige RZ4 2012 tips the scales at 4 485 lbs — 771 lbs more than the Tige Z1 2012 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.
For family outings this is probably the sharpest distinction between the two. The Tige RZ4 2012 is rated for 17 passengers, while the Tige Z1 2012 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Tige RZ4 2012 could be the deciding factor.
Bottom line: Choose the Tige RZ4 2012 if your priority is putting more people on the water — it handles 17 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Tige Z1 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
