When two boats share the same hull type — in this case both the Nitro 290 Sport 2011 and the Nitro Z-7 2011 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 — Nitro 290 Sport 2011 at 19,4 ft versus Nitro Z-7 2011 at 18,7 ft. At 235 lbs and 165 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 225 hp, the Nitro 290 Sport 2011 has a 25-hp advantage over the Nitro Z-7 2011's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 46 gal and 45 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Nitro 290 Sport 2011 is rated for 8 passengers, while the Nitro Z-7 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nitro 290 Sport 2011 could be the deciding factor.
