When two boats share the same hull type — in this case both the Alumaweld Blackhawk 2013 and the Alumaweld Intruder Inboard 2009 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 Blackhawk 2013 at 20,1 ft versus Alumaweld Intruder Inboard 2009 at 18,0 ft. At 146 lbs and 152 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 200 hp, the Alumaweld Intruder Inboard 2009 has a 50-hp advantage over the Alumaweld Blackhawk 2013'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 Alumaweld Intruder Inboard 2009 carries 47 gallons versus 38 gallons in the Alumaweld Blackhawk 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.
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 1 lbs per hp for the Alumaweld Blackhawk 2013. 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 Blackhawk 2013 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: The Alumaweld Blackhawk 2013 at 20,1 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.
