When two boats share the same hull type — in this case both the Shallow Sport 21 ft. Modified V 2012 and the Shallow Sport Latitude 27 ST 2011 are tunnel designs with composite 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?

The power gap is worth calling out. Rated to 300 hp, the Shallow Sport Latitude 27 ST 2011 has a 100-hp advantage over the Shallow Sport 21 ft. Modified V 2012's 200-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 21 ft. Modified V 2012 carries 65 gallons versus 15 gallons in the Shallow Sport Latitude 27 ST 2011. 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 Latitude 27 ST 2011 is rated for 11 passengers, while the Shallow Sport 21 ft. Modified V 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Shallow Sport Latitude 27 ST 2011 could be the deciding factor.
