The Hewescraft 180 SM 2012 is a modified-V design and the Hewescraft ProV 2013 is a deep-V design, so you're likely deciding between two noticeably 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 - Hewescraft 180 SM 2012 at 18,4 ft versus Hewescraft ProV 2013 at 20,3 ft. Weight tells a clearer story for trailering families: the Hewescraft ProV 2013 tips the scales at 1 700 lbs - 650 lbs less than the Hewescraft 180 SM 2012 at 1 050 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 Hewescraft ProV 2013 has a 60-hp advantage over the Hewescraft 180 SM 2012's 115-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Hewescraft ProV 2013 is rated for 7 passengers, while the Hewescraft 180 SM 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Hewescraft ProV 2013 could be the deciding factor.
Bottom line: Choose the Hewescraft ProV 2013 if your priority is putting more people on the water - it handles 7 passengers and at 20,3 ft it has the deck room to back that rating up comfortably. The Hewescraft 180 SM 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.
