Crestliner CR 1648 T 2006 vs Crestliner Kodiak 18 Tiller 2012 — Same Brand, Different Boat

The Crestliner CR 1648 T 2006 vs Crestliner Kodiak 18 Tiller 2012 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Crestliner CR 1648 T 2006 at 15,0 ft versus Crestliner Kodiak 18 Tiller 2012 at 18,0 ft. Weight tells a clearer story for trailering families: the Crestliner CR 1648 T 2006 tips the scales at 275 lbs — 194 lbs more than the Crestliner Kodiak 18 Tiller 2012 at 81 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 35-hp advantage over the Crestliner CR 1648 T 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 Kodiak 18 Tiller 2012 is rated for 6 passengers, while the Crestliner CR 1648 T 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 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 1 lbs per hp versus 8 lbs per hp for the Crestliner CR 1648 T 2006. 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.

Bottom line: Choose the Crestliner Kodiak 18 Tiller 2012 if your priority is putting more people on the water — it handles 6 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Crestliner CR 1648 T 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.

Crestliner CR 1648 T 2006 vs Crestliner Kodiak 18 Tiller 2012 — Common Questions

Which is the larger boat — the Crestliner CR 1648 T 2006 or the Crestliner Kodiak 18 Tiller 2012?
The Crestliner Kodiak 18 Tiller 2012 is the longer of the two at 18,0 feet overall. The Crestliner CR 1648 T 2006 comes in at 15,0 feet, making it roughly 3,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner CR 1648 T 2006 or the Crestliner Kodiak 18 Tiller 2012?
For trailering, the Crestliner Kodiak 18 Tiller 2012 has the edge at 81 lbs dry weight versus 275 lbs for the Crestliner CR 1648 T 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Crestliner Kodiak 18 Tiller 2012 is rated to a maximum of 70 hp, giving it the larger power ceiling. The Crestliner CR 1648 T 2006 tops out at 35 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Crestliner CR 1648 T 2006 is Coast Guard rated for 4 passengers, while the Crestliner Kodiak 18 Tiller 2012 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the better power-to-weight ratio?
The Crestliner Kodiak 18 Tiller 2012 has a better power-to-weight ratio at 1 lbs per hp compared to 8 lbs per hp for the Crestliner CR 1648 T 2006. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Crestliner Kodiak 18 Tiller 2012 measures 78" wide, compared to 7" for the Crestliner CR 1648 T 2006. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Are the Crestliner CR 1648 T 2006 and Crestliner Kodiak 18 Tiller 2012 from the same manufacturer?
Yes — both the Crestliner CR 1648 T 2006 and the Crestliner Kodiak 18 Tiller 2012 are built by Crestliner. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
