Matching a modified vee Princecraft Platinum SE 176 FnP 2011 against a deep vee Princecraft Sport 172 SC 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Princecraft Platinum SE 176 FnP 2011 at 17,5 ft versus Princecraft Sport 172 SC 2012 at 17,4 ft. Weight tells a clearer story for trailering families: the Princecraft Platinum SE 176 FnP 2011 tips the scales at 1 331 lbs — 157 lbs more than the Princecraft Sport 172 SC 2012 at 1 174 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.
Both boats share a closely matched power ceiling — 125 hp for the Princecraft Platinum SE 176 FnP 2011 and 125 hp for the Princecraft Sport 172 SC 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 26 gal and 26 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Princecraft Platinum SE 176 FnP 2011 is rated for 7 passengers, while the Princecraft Sport 172 SC 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Platinum SE 176 FnP 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Princecraft Sport 172 SC 2012 comes in at 9 lbs per hp versus 11 lbs per hp for the Princecraft Platinum SE 176 FnP 2011. 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.
Bottom line: Choose the Princecraft Platinum SE 176 FnP 2011 if your priority is putting more people on the water — it handles 7 passengers and at 17,5 ft it has the deck room to back that rating up comfortably. The Princecraft Sport 172 SC 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
