Alumacraft Competitor 175 CS 2011 vs Alumacraft Competitor 175 Sport 2012 — A Close Look at Two Deep Vees

When two boats share the same hull type — in this case both the Alumacraft Competitor 175 CS 2011 and the Alumacraft Competitor 175 Sport 2012 are deep 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?

On paper these two are close siblings in the size department — Alumacraft Competitor 175 CS 2011 at 17,7 ft versus Alumacraft Competitor 175 Sport 2012 at 17,7 ft. At 1 285 lbs and 1 375 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 150 hp for the Alumacraft Competitor 175 CS 2011 and 150 hp for the Alumacraft Competitor 175 Sport 2012. 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. Both carry nearly identical fuel loads — 38 gal and 35 gal — so range won't be a tiebreaker here.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumacraft Competitor 175 CS 2011 comes in at 9 lbs per hp versus 9 lbs per hp for the Alumacraft Competitor 175 Sport 2012. 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: The Alumacraft Competitor 175 CS 2011 and Alumacraft Competitor 175 Sport 2012 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Alumacraft Competitor 175 CS 2011 vs Alumacraft Competitor 175 Sport 2012 — Common Questions

Which is the larger boat — the Alumacraft Competitor 175 CS 2011 or the Alumacraft Competitor 175 Sport 2012?
The Alumacraft Competitor 175 Sport 2012 is the longer of the two at 17,7 feet overall. The Alumacraft Competitor 175 CS 2011 comes in at 17,7 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumacraft Competitor 175 CS 2011 or the Alumacraft Competitor 175 Sport 2012?
For trailering, the Alumacraft Competitor 175 CS 2011 has the edge at 1 285 lbs dry weight versus 1 375 lbs for the Alumacraft Competitor 175 Sport 2012. 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.
How many people can each boat hold?
The Alumacraft Competitor 175 CS 2011 is Coast Guard rated for 5 passengers, while the Alumacraft Competitor 175 Sport 2012 is certified for 5. 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 Alumacraft Competitor 175 CS 2011 has a better power-to-weight ratio at 9 lbs per hp compared to 9 lbs per hp for the Alumacraft Competitor 175 Sport 2012. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Alumacraft Competitor 175 CS 2011 and Alumacraft Competitor 175 Sport 2012 share an 95 in. (2.41 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Alumacraft Competitor 175 CS 2011 or the Alumacraft Competitor 175 Sport 2012?
The Alumacraft Competitor 175 CS 2011 has the bigger tank at 38 gallons, versus 35 gallons on the Alumacraft Competitor 175 Sport 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 Alumacraft Competitor 175 CS 2011 and Alumacraft Competitor 175 Sport 2012 from the same manufacturer?
Yes — both the Alumacraft Competitor 175 CS 2011 and the Alumacraft Competitor 175 Sport 2012 are built by Alumacraft. 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.
