When two boats share the same hull type — in this case both the Stratos 476 SF 2011 and the Stratos 486 SF 2008 are deep vee designs with fiberglass 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 — Stratos 476 SF 2011 at 17,5 ft versus Stratos 486 SF 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Stratos 486 SF 2008 tips the scales at 175 lbs — 160 lbs less than the Stratos 476 SF 2011 at 15 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 150 hp, the Stratos 486 SF 2008 has a 35-hp advantage over the Stratos 476 SF 2011's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Stratos 486 SF 2008 carries 36 gallons versus 23 gallons in the Stratos 476 SF 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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 Stratos 476 SF 2011 comes in at 0 lbs per hp versus 1 lbs per hp for the Stratos 486 SF 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.
