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

Matching a flat Alumaweld Flat Bottom 20 Foot 2009 against a modified vee Alumaweld Pacific 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 Pacific 2012 measures 25,3 feet overall (2012), giving it roughly 23,3 additional feet of deck space compared to the Alumaweld Flat Bottom 20 Foot 2009 at 2,0 feet (2009). At 14 lbs and 38 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 250 hp, the Alumaweld Pacific 2012 has a 135-hp advantage over the Alumaweld Flat Bottom 20 Foot 2009's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 3 gal and 1 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Alumaweld Pacific 2012 is rated for 8 passengers, while the Alumaweld Flat Bottom 20 Foot 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumaweld Pacific 2012 could be the deciding factor.

Bottom line: Choose the Alumaweld Pacific 2012 if your priority is putting more people on the water — it handles 8 passengers and at 25,3 ft it has the deck room to back that rating up comfortably. The Alumaweld Flat Bottom 20 Foot 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Alumaweld Flat Bottom 20 Foot 2009 vs Alumaweld Pacific 2012 — Common Questions

Which is the larger boat — the Alumaweld Flat Bottom 20 Foot 2009 or the Alumaweld Pacific 2012?
The Alumaweld Pacific 2012 is the longer of the two at 25,3 feet overall. The Alumaweld Flat Bottom 20 Foot 2009 comes in at 2,0 feet, making it roughly 23,3 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 Pacific 2012?
For trailering, the Alumaweld Flat Bottom 20 Foot 2009 has the edge at 14 lbs dry weight versus 38 lbs for the Alumaweld Pacific 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.
Which boat can handle a bigger outboard?
The Alumaweld Pacific 2012 is rated to a maximum of 250 hp, giving it the larger power ceiling. The Alumaweld Flat Bottom 20 Foot 2009 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 Foot 2009 is Coast Guard rated for 5 passengers, while the Alumaweld Pacific 2012 is certified for 8. 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 Pacific 2012 measures 101" wide, compared to 95" for the Alumaweld Flat Bottom 20 Foot 2009. 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.
How do the fuel tanks compare on the Alumaweld Flat Bottom 20 Foot 2009 and Alumaweld Pacific 2012?
Both boats carry similar fuel loads — 3 gallons and 1 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Alumaweld Flat Bottom 20 Foot 2009 and Alumaweld Pacific 2012 from the same manufacturer?
Yes — both the Alumaweld Flat Bottom 20 Foot 2009 and the Alumaweld Pacific 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.
