The Bennington 205 Si 2005 vs Bennington 2050GS 2008 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 205 Si 2005 at 2,0 ft versus Bennington 2050GS 2008 at 2,0 ft. Weight tells a clearer story for trailering families: the Bennington 2050GS 2008 tips the scales at 2 553 lbs — 2 398 lbs less than the Bennington 205 Si 2005 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.
The power gap is worth calling out. Rated to 75 hp, the Bennington 205 Si 2005 has a 52-hp advantage over the Bennington 2050GS 2008's 23-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 Bennington 2050GS 2008 is rated for 23 passengers, while the Bennington 205 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 2050GS 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Bennington 205 Si 2005 comes in at 2 lbs per hp versus 111 lbs per hp for the Bennington 2050GS 2008. 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 2050GS 2008 if your priority is putting more people on the water — it handles 23 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Bennington 205 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.
