Alumaweld Flat Bottom 20 Foot 2009 vs Alumaweld Free Drifter 2012 — Same Brand, Different Boat

Matching a flat Alumaweld Flat Bottom 20 Foot 2009 against a modified vee Alumaweld Free Drifter 2012 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 Free Drifter 2012 measures 18,1 feet overall (2012), giving it roughly 16,1 additional feet of deck space compared to the Alumaweld Flat Bottom 20 Foot 2009 at 2,0 feet (2009). At 14 lbs and 96 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.

Both boats share a closely matched power ceiling — 115 hp for the Alumaweld Flat Bottom 20 Foot 2009 and 115 hp for the Alumaweld Free Drifter 2012. 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 Free Drifter 2012 carries 37 gallons versus 3 gallons in the Alumaweld Flat Bottom 20 Foot 2009. 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 Free Drifter 2012 at 18,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Alumaweld Flat Bottom 20 Foot 2009 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 Foot 2009 vs Alumaweld Free Drifter 2012 — Common Questions

Which is the larger boat — the Alumaweld Flat Bottom 20 Foot 2009 or the Alumaweld Free Drifter 2012?
The Alumaweld Free Drifter 2012 is the longer of the two at 18,1 feet overall. The Alumaweld Flat Bottom 20 Foot 2009 comes in at 2,0 feet, making it roughly 16,1 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumaweld Flat Bottom 20 Foot 2009 or the Alumaweld Free Drifter 2012?
For trailering, the Alumaweld Flat Bottom 20 Foot 2009 has the edge at 14 lbs dry weight versus 96 lbs for the Alumaweld Free Drifter 2012. 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.
How many people can each boat hold?
The Alumaweld Flat Bottom 20 Foot 2009 is Coast Guard rated for 5 passengers, while the Alumaweld Free Drifter 2012 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 Foot 2009 measures 95" wide, compared to 84" for the Alumaweld Free Drifter 2012. 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 Foot 2009 or the Alumaweld Free Drifter 2012?
The Alumaweld Free Drifter 2012 has the bigger tank at 37 gallons, versus 3 gallons on the Alumaweld Flat Bottom 20 Foot 2009. That 34-gallon difference translates to roughly 102–170 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Alumaweld Flat Bottom 20 Foot 2009 and Alumaweld Free Drifter 2012 from the same manufacturer?
Yes — both the Alumaweld Flat Bottom 20 Foot 2009 and the Alumaweld Free Drifter 2012 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.
