Alumaweld Flat Bottom 20 Foot 2009 vs Alumaweld Stryker Inboard 2009 — Same Brand, Different Boat

Matching a flat Alumaweld Flat Bottom 20 Foot 2009 against a modified vee Alumaweld Stryker Inboard 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.

On paper these two are close siblings in the size department — Alumaweld Flat Bottom 20 Foot 2009 at 2,0 ft versus Alumaweld Stryker Inboard 2009 at 2,0 ft. Weight tells a clearer story for trailering families: the Alumaweld Stryker Inboard 2009 tips the scales at 154 lbs — 140 lbs less than the Alumaweld Flat Bottom 20 Foot 2009 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 200 hp, the Alumaweld Stryker Inboard 2009 has a 85-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. Fuel capacity breaks the other way: the Alumaweld Stryker Inboard 2009 carries 38 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Alumaweld Flat Bottom 20 Foot 2009 comes in at 0 lbs per hp versus 1 lbs per hp for the Alumaweld Stryker Inboard 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: Performance buyers should lean toward the Alumaweld Stryker Inboard 2009 and its 200-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Alumaweld Flat Bottom 20 Foot 2009 with its 115-hp rating is the more economical daily driver.
