Alumaweld Intruder Inboard 18 2008 vs Alumaweld Stryker Sport 2011 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the Alumaweld Intruder Inboard 18 2008 and the Alumaweld Stryker Sport 2011 are modified vee designs with aluminum 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 — Alumaweld Intruder Inboard 18 2008 at 18,0 ft versus Alumaweld Stryker Sport 2011 at 18,3 ft. Weight tells a clearer story for trailering families: the Alumaweld Stryker Sport 2011 tips the scales at 1 185 lbs — 983 lbs less than the Alumaweld Intruder Inboard 18 2008 at 202 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 330 hp, the Alumaweld Intruder Inboard 18 2008 has a 215-hp advantage over the Alumaweld Stryker Sport 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 Alumaweld Intruder Inboard 18 2008 carries 47 gallons versus 38 gallons in the Alumaweld Stryker Sport 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 Alumaweld Intruder Inboard 18 2008 and its 330-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Alumaweld Stryker Sport 2011 with its 115-hp rating is the more economical daily driver.

Alumaweld Intruder Inboard 18 2008 vs Alumaweld Stryker Sport 2011 — Common Questions

Which is the larger boat — the Alumaweld Intruder Inboard 18 2008 or the Alumaweld Stryker Sport 2011?
The Alumaweld Stryker Sport 2011 is the longer of the two at 18,3 feet overall. The Alumaweld Intruder Inboard 18 2008 comes in at 18,0 feet, making it roughly 0,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumaweld Intruder Inboard 18 2008 or the Alumaweld Stryker Sport 2011?
For trailering, the Alumaweld Intruder Inboard 18 2008 has the edge at 202 lbs dry weight versus 1 185 lbs for the Alumaweld Stryker Sport 2011. 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 Alumaweld Intruder Inboard 18 2008 is rated to a maximum of 330 hp, giving it the larger power ceiling. The Alumaweld Stryker Sport 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.
How many people can each boat hold?
The Alumaweld Intruder Inboard 18 2008 is Coast Guard rated for 5 passengers, while the Alumaweld Stryker Sport 2011 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.
Which boat is wider, and does it affect trailering?
The Alumaweld Stryker Sport 2011 measures 94" wide, compared to 89" for the Alumaweld Intruder Inboard 18 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.
Which boat has the larger fuel tank — the Alumaweld Intruder Inboard 18 2008 or the Alumaweld Stryker Sport 2011?
The Alumaweld Intruder Inboard 18 2008 has the bigger tank at 47 gallons, versus 38 gallons on the Alumaweld Stryker Sport 2011. That 9-gallon difference translates to roughly 27–45 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumaweld Intruder Inboard 18 2008 and Alumaweld Stryker Sport 2011 from the same manufacturer?
Yes — both the Alumaweld Intruder Inboard 18 2008 and the Alumaweld Stryker Sport 2011 are built by Alumaweld. 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.
