Alumaweld Flat Bottom 20 2008 vs Alumaweld Stryker Sport 2009 — Same Brand, Different Boat

Matching a flat Alumaweld Flat Bottom 20 2008 against a modified vee Alumaweld Stryker Sport 2009 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 Stryker Sport 2009 measures 16,0 feet overall (2009), giving it roughly 14,0 additional feet of deck space compared to the Alumaweld Flat Bottom 20 2008 at 2,0 feet (2008). At 14 lbs and 94 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 115 hp, the Alumaweld Flat Bottom 20 2008 has a 55-hp advantage over the Alumaweld Stryker Sport 2009's 60-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 Stryker Sport 2009 carries 18 gallons versus 3 gallons in the Alumaweld Flat Bottom 20 2008. 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumaweld Flat Bottom 20 2008 comes in at 0 lbs per hp versus 2 lbs per hp for the Alumaweld Stryker Sport 2009. 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: The Alumaweld Stryker Sport 2009 at 16,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Alumaweld Flat Bottom 20 2008 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.

The Alumaweld Stryker Sport 2009 is the longer of the two at 16,0 feet overall. The Alumaweld Flat Bottom 20 2008 comes in at 2,0 feet, making it roughly 14,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Alumaweld Flat Bottom 20 2008 or the Alumaweld Stryker Sport 2009?
For trailering, the Alumaweld Flat Bottom 20 2008 has the edge at 14 lbs dry weight versus 94 lbs for the Alumaweld Stryker Sport 2009. 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 Flat Bottom 20 2008 is rated to a maximum of 115 hp, giving it the larger power ceiling. The Alumaweld Stryker Sport 2009 tops out at 60 hp.

How many people can each boat hold?
The Alumaweld Flat Bottom 20 2008 is Coast Guard rated for 5 passengers, while the Alumaweld Stryker Sport 2009 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 has the better power-to-weight ratio?
The Alumaweld Flat Bottom 20 2008 has a better power-to-weight ratio at 0 lbs per hp compared to 2 lbs per hp for the Alumaweld Stryker Sport 2009. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Alumaweld Flat Bottom 20 2008 measures 95" wide, compared to 86" for the Alumaweld Stryker Sport 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.
Which boat has the larger fuel tank — the Alumaweld Flat Bottom 20 2008 or the Alumaweld Stryker Sport 2009?
The Alumaweld Stryker Sport 2009 has the bigger tank at 18 gallons, versus 3 gallons on the Alumaweld Flat Bottom 20 2008. That 15-gallon difference translates to roughly 45–75 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes — both the Alumaweld Flat Bottom 20 2008 and the Alumaweld Stryker Sport 2009 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.
