Stratos 186 XT 2011 vs Stratos 191 FS 2006 - Boat Spec Comparison

Q: Which is the larger boat — the Stratos 186 XT 2011 or the Stratos 191 FS 2006?

The Stratos 186 XT 2011 is the longer of the two at 18,8 feet overall. The Stratos 191 FS 2006 comes in at 18,0 feet, making it roughly 0,8 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The Stratos 191 FS 2006 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Stratos 186 XT 2011 tops out at 115 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Stratos 186 XT 2011 is Coast Guard rated for 5 passengers, while the Stratos 191 FS 2006 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.

Q: Which boat is wider, and does it affect trailering?

The Stratos 186 XT 2011 measures 91" wide, compared to 89" for the Stratos 191 FS 2006. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

Q: Which boat has the larger fuel tank — the Stratos 186 XT 2011 or the Stratos 191 FS 2006?

The Stratos 191 FS 2006 has the bigger tank at 38 gallons, versus 23 gallons on the Stratos 186 XT 2011. That 15-gallon difference translates to roughly 45–75 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Stratos 186 XT 2011 and Stratos 191 FS 2006 from the same manufacturer?

Yes — both the Stratos 186 XT 2011 and the Stratos 191 FS 2006 are built by Stratos. 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.

Detailed Evaluation & Buyer Recommendation

Stratos 186 XT 2011 vs Stratos 191 FS 2006 — Same Brand, Different Boat

The Stratos 186 XT 2011 vs Stratos 191 FS 2006 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.

The power gap is worth calling out. Rated to 175 hp, the Stratos 191 FS 2006 has a 60-hp advantage over the Stratos 186 XT 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 191 FS 2006 carries 38 gallons versus 23 gallons in the Stratos 186 XT 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.

Bottom line: Performance buyers should lean toward the Stratos 191 FS 2006 and its 175-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Stratos 186 XT 2011 with its 115-hp rating is the more economical daily driver.
