Both the Nitro 898 2008 and the Nitro Z-6 2008 are modified-V designs, both built in aluminium, so 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 898 2008 at 20,0 ft versus Nitro Z-6 2008 at 17,0 ft. Weight tells a clearer story for trailering families: the Nitro 898 2008 tips the scales at 1 760 lbs - 410 lbs more than the Nitro Z-6 2008 at 1 350 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.
The power gap is worth calling out. Rated to 225 hp, the Nitro 898 2008 has a 95-hp advantage over the Nitro Z-6 2008's 130-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Nitro 898 2008 carries 48 gallons versus 31 gallons in the Nitro Z-6 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 4 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 Nitro 898 2008 at 20,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Nitro Z-6 2008 at 17,0 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.
