Bennington 185 L 2004 vs Bennington 207 Si 2005 — Same Brand, Different Boat

The Bennington 185 L 2004 vs Bennington 207 Si 2005 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.

Size is the most obvious dividing line here. The Bennington 185 L 2004 measures 17,0 feet overall (2004), giving it roughly 15,0 additional feet of deck space compared to the Bennington 207 Si 2005 at 2,0 feet (2005). At 144 lbs and 155 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 — 75 hp for the Bennington 185 L 2004 and 75 hp for the Bennington 207 Si 2005. 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 — 26 gal and 26 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Bennington 185 L 2004 is rated for 9 passengers, while the Bennington 207 Si 2005 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 185 L 2004 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Bennington 185 L 2004 comes in at 2 lbs per hp versus 2 lbs per hp for the Bennington 207 Si 2005. 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 Bennington 185 L 2004 if your priority is putting more people on the water — it handles 9 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Bennington 207 Si 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.

Bennington 185 L 2004 vs Bennington 207 Si 2005 — Common Questions

Which is the larger boat — the Bennington 185 L 2004 or the Bennington 207 Si 2005?
The Bennington 185 L 2004 is the longer of the two at 17,0 feet overall. The Bennington 207 Si 2005 comes in at 2,0 feet, making it roughly 15,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Bennington 185 L 2004 or the Bennington 207 Si 2005?
For trailering, the Bennington 185 L 2004 has the edge at 144 lbs dry weight versus 155 lbs for the Bennington 207 Si 2005. 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 Bennington 185 L 2004 is Coast Guard rated for 9 passengers, while the Bennington 207 Si 2005 is certified for 1. 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 Bennington 185 L 2004 has a better power-to-weight ratio at 2 lbs per hp compared to 2 lbs per hp for the Bennington 207 Si 2005. 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 Bennington 185 L 2004 and Bennington 207 Si 2005 share an 8 ft 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.
How do the fuel tanks compare on the Bennington 185 L 2004 and Bennington 207 Si 2005?
Both boats carry similar fuel loads — 26 gallons and 26 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Bennington 185 L 2004 and Bennington 207 Si 2005 from the same manufacturer?
Yes — both the Bennington 185 L 2004 and the Bennington 207 Si 2005 are built by Bennington. 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.
