Crestliner Ambush 18 2012 vs Crestliner Batata Bay 1685 2010 — Same Brand, Different Boat

Matching a modified vee Crestliner Ambush 18 2012 against a pontoon Crestliner Batata Bay 1685 2010 means you're likely deciding between two genuinely 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 Ambush 18 2012 at 18,0 ft versus Crestliner Batata Bay 1685 2010 at 17,5 ft. Weight tells a clearer story for trailering families: the Crestliner Batata Bay 1685 2010 tips the scales at 1 575 lbs — 566 lbs less than the Crestliner Ambush 18 2012 at 1 009 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 Ambush 18 2012 has a 40-hp advantage over the Crestliner Batata Bay 1685 2010's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 22 gal and 25 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Crestliner Batata Bay 1685 2010 is rated for 7 passengers, while the Crestliner Ambush 18 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Batata Bay 1685 2010 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Crestliner Ambush 18 2012 comes in at 11 lbs per hp versus 32 lbs per hp for the Crestliner Batata Bay 1685 2010. 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 Batata Bay 1685 2010 if your priority is putting more people on the water — it handles 7 passengers and at 17,5 ft it has the deck room to back that rating up comfortably. The Crestliner Ambush 18 2012 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 Ambush 18 2012 vs Crestliner Batata Bay 1685 2010 — Common Questions

Which is the larger boat — the Crestliner Ambush 18 2012 or the Crestliner Batata Bay 1685 2010?
The Crestliner Ambush 18 2012 is the longer of the two at 18,0 feet overall. The Crestliner Batata Bay 1685 2010 comes in at 17,5 feet, making it roughly 0,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner Ambush 18 2012 or the Crestliner Batata Bay 1685 2010?
For trailering, the Crestliner Ambush 18 2012 has the edge at 1 009 lbs dry weight versus 1 575 lbs for the Crestliner Batata Bay 1685 2010. 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 Ambush 18 2012 is rated to a maximum of 90 hp, giving it the larger power ceiling. The Crestliner Batata Bay 1685 2010 tops out at 50 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 Ambush 18 2012 is Coast Guard rated for 4 passengers, while the Crestliner Batata Bay 1685 2010 is certified for 7. 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 Ambush 18 2012 has a better power-to-weight ratio at 11 lbs per hp compared to 32 lbs per hp for the Crestliner Batata Bay 1685 2010. 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 Batata Bay 1685 2010 measures 101" wide, compared to 79" for the Crestliner Ambush 18 2012. 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.
Which boat has the larger fuel tank — the Crestliner Ambush 18 2012 or the Crestliner Batata Bay 1685 2010?
The Crestliner Batata Bay 1685 2010 has the bigger tank at 25 gallons, versus 22 gallons on the Crestliner Ambush 18 2012. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crestliner Ambush 18 2012 and Crestliner Batata Bay 1685 2010 from the same manufacturer?
Yes — both the Crestliner Ambush 18 2012 and the Crestliner Batata Bay 1685 2010 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.
