When two boats share the same hull type — in this case both the Shallow Sport 15 ft. Scooter 2009 and the Shallow Sport 20 ft. Classic 2013 are tunnel designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Shallow Sport 15 ft. Scooter 2009 measures 15,0 feet overall (2009), giving it roughly 13,0 additional feet of deck space compared to the Shallow Sport 20 ft. Classic 2013 at 2,0 feet (2013). At 65 lbs and 85 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 200 hp, the Shallow Sport 20 ft. Classic 2013 has a 70-hp advantage over the Shallow Sport 15 ft. Scooter 2009's 130-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Shallow Sport 20 ft. Classic 2013 carries 43 gallons versus 35 gallons in the Shallow Sport 15 ft. Scooter 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Shallow Sport 20 ft. Classic 2013 is rated for 6 passengers, while the Shallow Sport 15 ft. Scooter 2009 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Shallow Sport 20 ft. Classic 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Shallow Sport 20 ft. Classic 2013 comes in at 0 lbs per hp versus 1 lbs per hp for the Shallow Sport 15 ft. Scooter 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: Choose the Shallow Sport 20 ft. Classic 2013 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Shallow Sport 15 ft. Scooter 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
