When two boats share the same hull type — in this case both the Alumaweld Intruder Sterndrive 18 2008 and the Alumaweld Stryker Inboard 2013 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 Sterndrive 18 2008 at 18,0 ft versus Alumaweld Stryker Inboard 2013 at 20,3 ft. Weight tells a clearer story for trailering families: the Alumaweld Intruder Sterndrive 18 2008 tips the scales at 1 955 lbs — 290 lbs more than the Alumaweld Stryker Inboard 2013 at 1 665 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.

Both boats share a closely matched power ceiling — 220 hp for the Alumaweld Intruder Sterndrive 18 2008 and 200 hp for the Alumaweld Stryker Inboard 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Alumaweld Intruder Sterndrive 18 2008 carries 47 gallons versus 38 gallons in the Alumaweld Stryker Inboard 2013. 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.
