Alumaweld Flat Bottom 20 Foot 2009 vs Alumaweld Super Vee LS 19 2008 — Same Brand, Different Boat

Matching a flat Alumaweld Flat Bottom 20 Foot 2009 against a modified vee Alumaweld Super Vee LS 19 2008 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 Super Vee LS 19 2008 measures 19,0 feet overall (2008), giving it roughly 17,0 additional feet of deck space compared to the Alumaweld Flat Bottom 20 Foot 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Alumaweld Super Vee LS 19 2008 tips the scales at 985 lbs — 971 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.

Both boats share a closely matched power ceiling — 115 hp for the Alumaweld Flat Bottom 20 Foot 2009 and 115 hp for the Alumaweld Super Vee LS 19 2008. 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 Super Vee LS 19 2008 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 Super Vee LS 19 2008 at 19,0 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.
