Stratos 21 MSX 2005 vs Stratos 476 SF 2008 - Boat Spec Comparison

Q: Which is the larger boat — the Stratos 21 MSX 2005 or the Stratos 476 SF 2008?

The Stratos 476 SF 2008 is the longer of the two at 17,0 feet overall. The Stratos 21 MSX 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.

Q: Which boat can handle a bigger outboard?

The Stratos 21 MSX 2005 is rated to a maximum of 250 hp, giving it the larger power ceiling. The Stratos 476 SF 2008 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 21 MSX 2005 is Coast Guard rated for 6 passengers, while the Stratos 476 SF 2008 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 21 MSX 2005 measures 97" wide, compared to 93" for the Stratos 476 SF 2008. 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 21 MSX 2005 or the Stratos 476 SF 2008?

The Stratos 21 MSX 2005 has the bigger tank at 54 gallons, versus 23 gallons on the Stratos 476 SF 2008. That 31-gallon difference translates to roughly 93–155 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Stratos 21 MSX 2005 and Stratos 476 SF 2008 from the same manufacturer?

Yes — both the Stratos 21 MSX 2005 and the Stratos 476 SF 2008 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 21 MSX 2005 vs Stratos 476 SF 2008 — Same Brand, Different Boat

The Stratos 21 MSX 2005 vs Stratos 476 SF 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.

The power gap is worth calling out. Rated to 250 hp, the Stratos 21 MSX 2005 has a 135-hp advantage over the Stratos 476 SF 2008'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 21 MSX 2005 carries 54 gallons versus 23 gallons in the Stratos 476 SF 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Stratos 21 MSX 2005 is rated for 6 passengers, while the Stratos 476 SF 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stratos 21 MSX 2005 could be the deciding factor.

Bottom line: Choose the Stratos 21 MSX 2005 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Stratos 476 SF 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
