When two boats share the same hull type — in this case both the Nitro 901 CDX 2008 and the Nitro 929 CDX 2008 are modified vee designs with aluminum 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 Nitro 901 CDX 2008 measures 19,0 feet overall (2008), giving it roughly 17,0 additional feet of deck space compared to the Nitro 929 CDX 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Nitro 929 CDX 2008 tips the scales at 1 919 lbs — 204 lbs less than the Nitro 901 CDX 2008 at 1 715 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 300 hp, the Nitro 929 CDX 2008 has a 100-hp advantage over the Nitro 901 CDX 2008'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 — 57 gal and 57 gal — so range won't be a tiebreaker here.
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 901 CDX 2008 at 19,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Nitro 929 CDX 2008 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.
