When two boats share the same hull type — in this case both the Alumaweld Intruder Inboard 2013 and the Alumaweld Intruder Sterndrive 20 2008 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?
Size is the most obvious dividing line here. The Alumaweld Intruder Inboard 2013 measures 20,4 feet overall (2013), giving it roughly 18,4 additional feet of deck space compared to the Alumaweld Intruder Sterndrive 20 2008 at 2,0 feet (2008). At 176 lbs and 226 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 225 hp, the Alumaweld Intruder Sterndrive 20 2008 has a 25-hp advantage over the Alumaweld Intruder Inboard 2013's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 6 gal and 6 gal — so range won't be a tiebreaker here.
Both boats are rated for 6 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: The Alumaweld Intruder Inboard 2013 at 20,4 ft is the right call if deck space, comfort, and entertaining are top of your list. The Alumaweld Intruder Sterndrive 20 2008 at 2,0 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.
