Both the Xpress HDSC Series - HD20SCA 2008 and the Xpress Striker 16 2013 are modified-V designs, both built in aluminium, so 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?
Size is the most obvious dividing line here. The Xpress HDSC Series - HD20SCA 2008 measures 20,0 feet overall (2008), giving it roughly 4,0 additional feet of deck space compared to the Xpress Striker 16 2013 at 16,0 feet (2013). Weight tells a clearer story for trailering families: the Xpress HDSC Series - HD20SCA 2008 tips the scales at 1 190 lbs - 523 lbs more than the Xpress Striker 16 2013 at 667 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 130 hp, the Xpress HDSC Series - HD20SCA 2008 has a 90-hp advantage over the Xpress Striker 16 2013's 40-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 Xpress HDSC Series - HD20SCA 2008 is rated for 6 passengers, while the Xpress Striker 16 2013 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Xpress HDSC Series - HD20SCA 2008 could be the deciding factor.
Bottom line: Choose the Xpress HDSC Series - HD20SCA 2008 if your priority is putting more people on the water - it handles 6 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Xpress Striker 16 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
