Matching a modified vee Alumaweld Intruder Sterndrive 18 2008 against a inflatable non rigid Alumaweld Super Vee Pro 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 Intruder Sterndrive 18 2008 at 18,0 ft versus Alumaweld Super Vee Pro 2009 at 21,0 ft. Weight tells a clearer story for trailering families: the Alumaweld Intruder Sterndrive 18 2008 tips the scales at 1 955 lbs — 1 793 lbs more than the Alumaweld Super Vee Pro 2009 at 162 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 250 hp, the Alumaweld Super Vee Pro 2009 has a 30-hp advantage over the Alumaweld Intruder Sterndrive 18 2008's 220-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 47 gal and 45 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Alumaweld Super Vee Pro 2009 is rated for 7 passengers, while the Alumaweld Intruder Sterndrive 18 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Alumaweld Super Vee Pro 2009 could be the deciding factor.
Bottom line: Choose the Alumaweld Super Vee Pro 2009 if your priority is putting more people on the water — it handles 7 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Alumaweld Intruder Sterndrive 18 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
