When two boats share the same hull type — in this case both the Princecraft Platinum SE 176 2013 and the Princecraft Platinum SE 186 2013 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 2013 at 17,5 ft versus Princecraft Platinum SE 186 2013 at 18,5 ft. Weight tells a clearer story for trailering families: the Princecraft Platinum SE 186 2013 tips the scales at 1 545 lbs — 110 lbs less than the Princecraft Platinum SE 176 2013 at 1 435 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 175 hp, the Princecraft Platinum SE 186 2013 has a 25-hp advantage over the Princecraft Platinum SE 176 2013's 150-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 4 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 186 2013 is rated for 8 passengers, while the Princecraft Platinum SE 176 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Platinum SE 186 2013 could be the deciding factor.
