The Bennington 185SL 2009 vs Bennington 205 Si 2004 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 — Bennington 185SL 2009 at 18,0 ft versus Bennington 205 Si 2004 at 19,0 ft. Weight tells a clearer story for trailering families: the Bennington 185SL 2009 tips the scales at 1 611 lbs — 1 456 lbs more than the Bennington 205 Si 2004 at 155 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.
Both boats share a closely matched power ceiling — 60 hp for the Bennington 185SL 2009 and 75 hp for the Bennington 205 Si 2004. 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.
For family outings this is probably the sharpest distinction between the two. The Bennington 185SL 2009 is rated for 23 passengers, while the Bennington 205 Si 2004 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bennington 185SL 2009 could be the deciding factor.
Bottom line: Choose the Bennington 185SL 2009 if your priority is putting more people on the water — it handles 23 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Bennington 205 Si 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
