When two boats share the same hull type — in this case both the Alumaweld Intruder Inboard 2009 and the Alumaweld Stryker Inboard 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 2009 at 18,0 ft versus Alumaweld Stryker Inboard 2011 at 20,3 ft. Weight tells a clearer story for trailering families: the Alumaweld Stryker Inboard 2011 tips the scales at 1 665 lbs — 1 513 lbs less than the Alumaweld Intruder Inboard 2009 at 152 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 — 200 hp for the Alumaweld Intruder Inboard 2009 and 200 hp for the Alumaweld Stryker Inboard 2011. 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 Inboard 2009 carries 47 gallons versus 38 gallons in the Alumaweld Stryker Inboard 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumaweld Intruder Inboard 2009 comes in at 1 lbs per hp versus 8 lbs per hp for the Alumaweld Stryker Inboard 2011. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
The Alumaweld Intruder Inboard 2009 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Alumaweld Stryker Inboard 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The Alumaweld Stryker Inboard 2011 at 20,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Alumaweld Intruder Inboard 2009 at 18,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
