Matching a flat Shallow Stalker Cat 204 2010 against a modified vee Shallow Stalker V-20 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 — Shallow Stalker Cat 204 2010 at 20,3 ft versus Shallow Stalker V-20 2009 at 19,8 ft. At 118 lbs and 108 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 150 hp, the Shallow Stalker Cat 204 2010 has a 60-hp advantage over the Shallow Stalker V-20 2009's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 4 gal and 4 gal — so range won't be a tiebreaker here.
Both boats are rated for 6 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: Performance buyers should lean toward the Shallow Stalker Cat 204 2010 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Shallow Stalker V-20 2009 with its 90-hp rating is the more economical daily driver.
