The Crestliner Kodiak 18 Tiller 2012 is a deep-V design and the Crestliner Retriever 1546 DS 2011 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 - Crestliner Kodiak 18 Tiller 2012 at 18,0 ft versus Crestliner Retriever 1546 DS 2011 at 15,0 ft. Weight tells a clearer story for trailering families: the Crestliner Kodiak 18 Tiller 2012 tips the scales at 810 lbs - 310 lbs more than the Crestliner Retriever 1546 DS 2011 at 500 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 70 hp, the Crestliner Kodiak 18 Tiller 2012 has a 30-hp advantage over the Crestliner Retriever 1546 DS 2011'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 Crestliner Kodiak 18 Tiller 2012 is rated for 6 passengers, while the Crestliner Retriever 1546 DS 2011 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Kodiak 18 Tiller 2012 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Kodiak 18 Tiller 2012 comes in at 12 lbs per hp versus 13 lbs per hp for the Crestliner Retriever 1546 DS 2011. 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.
