Matching a deep vee Regal 2520 FasDeck 2008 against a modified vee Regal 2860 Window Express 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Regal 2860 Window Express 2008 measures 29,0 feet overall (2008), giving it roughly 4,0 additional feet of deck space compared to the Regal 2520 FasDeck 2008 at 25,0 feet (2008). Weight tells a clearer story for trailering families: the Regal 2520 FasDeck 2008 tips the scales at 465 lbs — 456 lbs more 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 power gap is worth calling out. Rated to 375 hp, the Regal 2520 FasDeck 2008 has a 373-hp advantage over the Regal 2860 Window Express 2008'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 Regal 2520 FasDeck 2008 carries 62 gallons versus 1 gallons in the Regal 2860 Window Express 2008. 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 Regal 2860 Window Express 2008 is rated for 8 passengers, while the Regal 2520 FasDeck 2008 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Regal 2860 Window Express 2008 could be the deciding factor.
Bottom line: Choose the Regal 2860 Window Express 2008 if your priority is putting more people on the water — it handles 8 passengers and at 29,0 ft it has the deck room to back that rating up comfortably. The Regal 2520 FasDeck 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
