When two boats share the same hull type — in this case both the Princecraft Sport 174 2010 and the Princecraft Starfish 20 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?

On paper these two are close siblings in the size department — Princecraft Sport 174 2010 at 17,4 ft versus Princecraft Starfish 20 2008 at 16,0 ft. Weight tells a clearer story for trailering families: the Princecraft Sport 174 2010 tips the scales at 1 289 lbs — 1 257 lbs more than the Princecraft Starfish 20 2008 at 32 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 115 hp, the Princecraft Sport 174 2010 has a 75-hp advantage over the Princecraft Starfish 20 2008's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 7 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Princecraft Starfish 20 2008 comes in at 1 lbs per hp versus 11 lbs per hp for the Princecraft Sport 174 2010. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
