When two boats share the same hull type — in this case both the Regal 2860 Window Express 2008 and the Regal 4080 Sportyacht 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 Regal 4080 Sportyacht 2010 measures 40,1 feet overall (2010), giving it roughly 11,1 additional feet of deck space compared to the Regal 2860 Window Express 2008 at 29,0 feet (2008). Weight tells a clearer story for trailering families: the Regal 4080 Sportyacht 2010 tips the scales at 193 lbs — 184 lbs less than the Regal 2860 Window Express 2008 at 9 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 Regal 2860 Window Express 2008 carries a rated maximum of 2 hp.

On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
