When two boats share the same hull type — in this case both the Alumacraft Angler Tiller 2010 and the Alumacraft Navigator 175 Sport 2007 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?

On paper these two are close siblings in the size department — Alumacraft Angler Tiller 2010 at 16,0 ft versus Alumacraft Navigator 175 Sport 2007 at 17,0 ft. Weight tells a clearer story for trailering families: the Alumacraft Navigator 175 Sport 2007 tips the scales at 1 357 lbs — 892 lbs less than the Alumacraft Angler Tiller 2010 at 465 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 Alumacraft Navigator 175 Sport 2007 tops out at 150 hp. Engine specs for the Alumacraft Angler Tiller 2010 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Alumacraft Navigator 175 Sport 2007 is rated for 5 passengers, while the Alumacraft Angler Tiller 2010 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumacraft Navigator 175 Sport 2007 could be the deciding factor.
