Matching a modified vee Princecraft Platinum SE 176 2011 against a deep vee Princecraft Xpedition 170 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 2011 at 17,5 ft versus Princecraft Xpedition 170 SC 2012 at 16,9 ft. Weight tells a clearer story for trailering families: the Princecraft Platinum SE 176 2011 tips the scales at 1 435 lbs — 380 lbs more than the Princecraft Xpedition 170 SC 2012 at 1 055 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 150 hp, the Princecraft Platinum SE 176 2011 has a 35-hp advantage over the Princecraft Xpedition 170 SC 2012's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 4 gal and 2 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 2011 is rated for 7 passengers, while the Princecraft Xpedition 170 SC 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Platinum SE 176 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Princecraft Xpedition 170 SC 2012 comes in at 9 lbs per hp versus 10 lbs per hp for the Princecraft Platinum SE 176 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 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 Xpedition 170 SC 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
