When two boats share the same hull type — in this case both the Alumaweld Free Drifter 2013 and the Alumaweld Intruder Inboard 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 Inboard 2010 at 20,1 ft. At 96 lbs and 176 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 2010 has a 85-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 Free Drifter 2013 carries 37 gallons versus 6 gallons in the Alumaweld Intruder Inboard 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Alumaweld Intruder Inboard 2010 is rated for 6 passengers, while the Alumaweld Free Drifter 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumaweld Intruder Inboard 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumaweld Free Drifter 2013 comes in at 1 lbs per hp versus 1 lbs per hp for the Alumaweld Intruder Inboard 2010. 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 2010 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Alumaweld Free Drifter 2013 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: Choose the Alumaweld Intruder Inboard 2010 if your priority is putting more people on the water — it handles 6 passengers and at 20,1 ft it has the deck room to back that rating up comfortably. The Alumaweld Free Drifter 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
