Alumaweld Flat Bottom 20 ft. 2010 vs Alumaweld Intruder Sterndrive 2010 — Same Brand, Different Boat

Matching a flat Alumaweld Flat Bottom 20 ft. 2010 against a modified vee Alumaweld Intruder Sterndrive 2010 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 Sterndrive 2010 measures 18,2 feet overall (2010), giving it roughly 16,2 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 Sterndrive 2010 tips the scales at 1 955 lbs — 1 941 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.

The power gap is worth calling out. Rated to 220 hp, the Alumaweld Intruder Sterndrive 2010 has a 105-hp advantage over the Alumaweld Flat Bottom 20 ft. 2010'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 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.

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.

Bottom line: The Alumaweld Intruder Sterndrive 2010 at 18,2 ft is the right call if deck space, comfort, and entertaining are top of your list. The Alumaweld Flat Bottom 20 ft. 2010 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.

Alumaweld Flat Bottom 20 ft. 2010 vs Alumaweld Intruder Sterndrive 2010 — Common Questions

Which is the larger boat — the Alumaweld Flat Bottom 20 ft. 2010 or the Alumaweld Intruder Sterndrive 2010?
The Alumaweld Intruder Sterndrive 2010 is the longer of the two at 18,2 feet overall. The Alumaweld Flat Bottom 20 ft. 2010 comes in at 2,0 feet, making it roughly 16,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumaweld Flat Bottom 20 ft. 2010 or the Alumaweld Intruder Sterndrive 2010?
For trailering, the Alumaweld Flat Bottom 20 ft. 2010 has the edge at 14 lbs dry weight versus 1 955 lbs for the Alumaweld Intruder Sterndrive 2010. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Alumaweld Intruder Sterndrive 2010 is rated to a maximum of 220 hp, giving it the larger power ceiling. The Alumaweld Flat Bottom 20 ft. 2010 tops out at 115 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Alumaweld Flat Bottom 20 ft. 2010 is Coast Guard rated for 5 passengers, while the Alumaweld Intruder Sterndrive 2010 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Alumaweld Flat Bottom 20 ft. 2010 measures 95" wide, compared to 89" for the Alumaweld Intruder Sterndrive 2010. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Alumaweld Flat Bottom 20 ft. 2010 or the Alumaweld Intruder Sterndrive 2010?
The Alumaweld Intruder Sterndrive 2010 has the bigger tank at 47 gallons, versus 3 gallons on the Alumaweld Flat Bottom 20 ft. 2010. That 44-gallon difference translates to roughly 132–220 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumaweld Flat Bottom 20 ft. 2010 and Alumaweld Intruder Sterndrive 2010 from the same manufacturer?
Yes — both the Alumaweld Flat Bottom 20 ft. 2010 and the Alumaweld Intruder Sterndrive 2010 are built by Alumaweld. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
