The Trophy 163 CC 2010 is a deep-V design and the Trophy 1901 Bay Boat 2008 is a modified-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 - Trophy 163 CC 2010 at 16,0 ft versus Trophy 1901 Bay Boat 2008 at 19,0 ft. Weight tells a clearer story for trailering families: the Trophy 1901 Bay Boat 2008 tips the scales at 1 900 lbs - 600 lbs less than the Trophy 163 CC 2010 at 1 300 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 Trophy 1901 Bay Boat 2008 has a 90-hp advantage over the Trophy 163 CC 2010's 60-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Trophy 1901 Bay Boat 2008 carries 56 gallons versus 20 gallons in the Trophy 163 CC 2010. 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 Trophy 1901 Bay Boat 2008 is rated for 5 passengers, while the Trophy 163 CC 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Trophy 1901 Bay Boat 2008 could be the deciding factor.
Bottom line: Choose the Trophy 1901 Bay Boat 2008 if your priority is putting more people on the water - it handles 5 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Trophy 163 CC 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
