When two boats share the same hull type — in this case both the Lowe RV170SC 2010 and the Lowe Sport Deck - SD224 2013 are modified vee designs with aluminum 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 Lowe Sport Deck - SD224 2013 measures 22,0 feet overall (2013), giving it roughly 4,8 additional feet of deck space compared to the Lowe RV170SC 2010 at 17,3 feet (2010). Weight tells a clearer story for trailering families: the Lowe RV170SC 2010 tips the scales at 789 lbs — 571 lbs more than the Lowe Sport Deck - SD224 2013 at 218 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 175 hp, the Lowe Sport Deck - SD224 2013 has a 100-hp advantage over the Lowe RV170SC 2010's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Lowe Sport Deck - SD224 2013 is rated for 12 passengers, while the Lowe RV170SC 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe Sport Deck - SD224 2013 could be the deciding factor.
