Matching a flat Alumaweld Flat Bottom 20 ft. 2010 against a modified vee Alumaweld Intruder Outboard 18 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Alumaweld Intruder Outboard 18 2008 measures 18,0 feet overall (2008), giving it roughly 16,0 additional feet of deck space compared to the Alumaweld Flat Bottom 20 ft. 2010 at 2,0 feet (2010). Weight tells a clearer story for trailering families: the Alumaweld Intruder Outboard 18 2008 tips the scales at 132 lbs — 118 lbs less than the Alumaweld Flat Bottom 20 ft. 2010 at 14 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 — 115 hp for the Alumaweld Flat Bottom 20 ft. 2010 and 115 hp for the Alumaweld Intruder Outboard 18 2008. 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 Outboard 18 2008 carries 47 gallons versus 3 gallons in the Alumaweld Flat Bottom 20 ft. 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 Flat Bottom 20 ft. 2010 is rated for 5 passengers, while the Alumaweld Intruder Outboard 18 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumaweld Flat Bottom 20 ft. 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Alumaweld Flat Bottom 20 ft. 2010 comes in at 0 lbs per hp versus 1 lbs per hp for the Alumaweld Intruder Outboard 18 2008. 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.
Bottom line: Choose the Alumaweld Flat Bottom 20 ft. 2010 if your priority is putting more people on the water — it handles 5 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Alumaweld Intruder Outboard 18 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
