When two boats share the same hull type — in this case both the Crestliner C 2070 VS 2007 and the Crestliner Retriever 1650 DS 2011 are modified 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?

Size is the most obvious dividing line here. The Crestliner Retriever 1650 DS 2011 measures 16,0 feet overall (2011), giving it roughly 14,0 additional feet of deck space compared to the Crestliner C 2070 VS 2007 at 2,0 feet (2007). Weight tells a clearer story for trailering families: the Crestliner C 2070 VS 2007 tips the scales at 1 365 lbs — 1 308 lbs more than the Crestliner Retriever 1650 DS 2011 at 57 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 90 hp, the Crestliner C 2070 VS 2007 has a 40-hp advantage over the Crestliner Retriever 1650 DS 2011's 50-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 VS 2007 is rated for 7 passengers, while the Crestliner Retriever 1650 DS 2011 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 VS 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Retriever 1650 DS 2011 comes in at 1 lbs per hp versus 15 lbs per hp for the Crestliner C 2070 VS 2007. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
