Sylvan 2240 Space Ship I/O 2005 vs Sylvan Mirage 8522 F-N-C 2011 — Same Brand, Different Boat

The Sylvan 2240 Space Ship I/O 2005 vs Sylvan Mirage 8522 F-N-C 2011 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 — Sylvan 2240 Space Ship I/O 2005 at 24,0 ft versus Sylvan Mirage 8522 F-N-C 2011 at 22,3 ft. Weight tells a clearer story for trailering families: the Sylvan 2240 Space Ship I/O 2005 tips the scales at 2 945 lbs — 2 924 lbs more than the Sylvan Mirage 8522 F-N-C 2011 at 21 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 425 hp, the Sylvan 2240 Space Ship I/O 2005 has a 275-hp advantage over the Sylvan Mirage 8522 F-N-C 2011's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sylvan 2240 Space Ship I/O 2005 carries 51 gallons versus 24 gallons in the Sylvan Mirage 8522 F-N-C 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 13 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 Sylvan 2240 Space Ship I/O 2005 and its 425-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sylvan Mirage 8522 F-N-C 2011 with its 150-hp rating is the more economical daily driver.

Sylvan 2240 Space Ship I/O 2005 vs Sylvan Mirage 8522 F-N-C 2011 — Common Questions

Which is the larger boat — the Sylvan 2240 Space Ship I/O 2005 or the Sylvan Mirage 8522 F-N-C 2011?
The Sylvan 2240 Space Ship I/O 2005 is the longer of the two at 24,0 feet overall. The Sylvan Mirage 8522 F-N-C 2011 comes in at 22,3 feet, making it roughly 1,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sylvan 2240 Space Ship I/O 2005 or the Sylvan Mirage 8522 F-N-C 2011?
For trailering, the Sylvan Mirage 8522 F-N-C 2011 has the edge at 21 lbs dry weight versus 2 945 lbs for the Sylvan 2240 Space Ship I/O 2005. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Sylvan 2240 Space Ship I/O 2005 is rated to a maximum of 425 hp, giving it the larger power ceiling. The Sylvan Mirage 8522 F-N-C 2011 tops out at 150 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.
How many people can each boat hold?
The Sylvan 2240 Space Ship I/O 2005 is Coast Guard rated for 13 passengers, while the Sylvan Mirage 8522 F-N-C 2011 is certified for 13. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Sylvan 2240 Space Ship I/O 2005 and Sylvan Mirage 8522 F-N-C 2011 share an 102 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Sylvan 2240 Space Ship I/O 2005 or the Sylvan Mirage 8522 F-N-C 2011?
The Sylvan 2240 Space Ship I/O 2005 has the bigger tank at 51 gallons, versus 24 gallons on the Sylvan Mirage 8522 F-N-C 2011. That 27-gallon difference translates to roughly 81–135 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sylvan 2240 Space Ship I/O 2005 and Sylvan Mirage 8522 F-N-C 2011 from the same manufacturer?
Yes — both the Sylvan 2240 Space Ship I/O 2005 and the Sylvan Mirage 8522 F-N-C 2011 are built by Sylvan. 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.
