When two boats share the same hull type — in this case both the Princecraft Platinum SE 176 FnP 2013 and the Princecraft Xpedition 170 BT 2012 are deep 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 Platinum SE 176 FnP 2013 at 17,4 ft versus Princecraft Xpedition 170 BT 2012 at 16,9 ft. Weight tells a clearer story for trailering families: the Princecraft Platinum SE 176 FnP 2013 tips the scales at 1 331 lbs — 1 234 lbs more than the Princecraft Xpedition 170 BT 2012 at 97 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 125 hp, the Princecraft Platinum SE 176 FnP 2013 has a 50-hp advantage over the Princecraft Xpedition 170 BT 2012's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Princecraft Platinum SE 176 FnP 2013 carries 26 gallons versus 2 gallons in the Princecraft Xpedition 170 BT 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Princecraft Platinum SE 176 FnP 2013 is rated for 7 passengers, while the Princecraft Xpedition 170 BT 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 FnP 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Princecraft Xpedition 170 BT 2012 comes in at 1 lbs per hp versus 11 lbs per hp for the Princecraft Platinum SE 176 FnP 2013. 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 2013 if your priority is putting more people on the water — it handles 7 passengers and at 17,4 ft it has the deck room to back that rating up comfortably. The Princecraft Xpedition 170 BT 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.
