When two boats share the same hull type — in this case both the Regulator 26 FS 2012 and the Regulator 34SS 2010 are modified vee 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 Regulator 34SS 2010 measures 33,8 feet overall (2010), giving it roughly 8,0 additional feet of deck space compared to the Regulator 26 FS 2012 at 25,8 feet (2012). Weight tells a clearer story for trailering families: the Regulator 34SS 2010 tips the scales at 11 115 lbs — 4 899 lbs less than the Regulator 26 FS 2012 at 6 216 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 500 hp, the Regulator 26 FS 2012 has a 150-hp advantage over the Regulator 34SS 2010's 350-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Regulator 34SS 2010 carries 38 gallons versus 2 gallons in the Regulator 26 FS 2012. 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 Regulator 34SS 2010 is rated for 11 passengers, while the Regulator 26 FS 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Regulator 34SS 2010 could be the deciding factor.
