When two boats share the same hull type — in this case both the Lowe RV170 Bay 2010 and the Lowe V1257 2012 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 RV170 Bay 2010 measures 17,3 feet overall (2010), giving it roughly 5,2 additional feet of deck space compared to the Lowe V1257 2012 at 12,1 feet (2012). Weight tells a clearer story for trailering families: the Lowe RV170 Bay 2010 tips the scales at 789 lbs — 661 lbs more than the Lowe V1257 2012 at 128 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 75 hp, the Lowe RV170 Bay 2010 has a 65-hp advantage over the Lowe V1257 2012's 10-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 RV170 Bay 2010 is rated for 4 passengers, while the Lowe V1257 2012 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe RV170 Bay 2010 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Lowe RV170 Bay 2010 comes in at 11 lbs per hp versus 13 lbs per hp for the Lowe V1257 2012. 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.
