When two boats share the same hull type — in this case both the Regulator 28 FS 2011 and the Regulator 34SS 2011 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 2011 measures 33,8 feet overall (2011), giving it roughly 6,3 additional feet of deck space compared to the Regulator 28 FS 2011 at 27,6 feet (2011). Weight tells a clearer story for trailering families: the Regulator 34SS 2011 tips the scales at 11 115 lbs — 10 289 lbs less than the Regulator 28 FS 2011 at 826 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 Regulator 28 FS 2011 carries a rated maximum of 600 hp. Engine data for the Regulator 34SS 2011 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Regulator 28 FS 2011 carries 235 gallons versus 38 gallons in the Regulator 34SS 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 Regulator 34SS 2011 is rated for 11 passengers, while the Regulator 28 FS 2011 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Regulator 34SS 2011 could be the deciding factor.
