Both the Crestliner C 2070 V 2008 and the Crestliner Sportsman 14 SC 2006 are modified-V designs, 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 Crestliner C 2070 V 2008 measures 20,0 feet overall (2008), giving it roughly 6,0 additional feet of deck space compared to the Crestliner Sportsman 14 SC 2006 at 14,0 feet (2006). Weight tells a clearer story for trailering families: the Crestliner C 2070 V 2008 tips the scales at 1 340 lbs - 930 lbs more than the Crestliner Sportsman 14 SC 2006 at 410 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 60 hp, the Crestliner C 2070 V 2008 has a 25-hp advantage over the Crestliner Sportsman 14 SC 2006's 35-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 Crestliner C 2070 V 2008 is rated for 7 passengers, while the Crestliner Sportsman 14 SC 2006 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner C 2070 V 2008 could be the deciding factor.
Bottom line: Choose the Crestliner C 2070 V 2008 if your priority is putting more people on the water - it handles 7 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Crestliner Sportsman 14 SC 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
