When two boats share the same hull type — in this case both the Alumaweld Free Drifter 2013 and the Alumaweld Intruder Sterndrive 2010 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 Free Drifter 2013 at 18,1 ft versus Alumaweld Intruder Sterndrive 2010 at 18,2 ft. Weight tells a clearer story for trailering families: the Alumaweld Intruder Sterndrive 2010 tips the scales at 1 955 lbs — 1 859 lbs less than the Alumaweld Free Drifter 2013 at 96 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 220 hp, the Alumaweld Intruder Sterndrive 2010 has a 105-hp advantage over the Alumaweld Free Drifter 2013'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 Sterndrive 2010 carries 47 gallons versus 37 gallons in the Alumaweld Free Drifter 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.
