Both the Crestliner C 2070 V 2010 and the Crestliner Kodiak 18 Tiller 2011 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?

On paper these two are close siblings in the size department - Crestliner C 2070 V 2010 at 20,0 ft versus Crestliner Kodiak 18 Tiller 2011 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner C 2070 V 2010 tips the scales at 1 340 lbs - 530 lbs more than the Crestliner Kodiak 18 Tiller 2011 at 810 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.

Both boats share a closely matched power ceiling - 60 hp for the Crestliner C 2070 V 2010 and 65 hp for the Crestliner Kodiak 18 Tiller 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

For family outings this is probably the sharpest distinction between the two. The Crestliner C 2070 V 2010 is rated for 7 passengers, while the Crestliner Kodiak 18 Tiller 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner C 2070 V 2010 could be the deciding factor.
