When two boats share the same hull type — in this case both the Regulator 30 Express 2010 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 30 Express 2010 measures 38,0 feet overall (2010), giving it roughly 4,2 additional feet of deck space compared to the Regulator 34SS 2010 at 33,8 feet (2010). Weight tells a clearer story for trailering families: the Regulator 30 Express 2010 tips the scales at 13 208 lbs — 2 093 lbs more than the Regulator 34SS 2010 at 11 115 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 350 hp, the Regulator 34SS 2010 has a 348-hp advantage over the Regulator 30 Express 2010's 2-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 3 gallons in the Regulator 30 Express 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 11 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
