The Lund 1775 Pro-V SE 2013 is a deep-V design and the Lund 2075 Pro-V SE 2011 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Lund 1775 Pro-V SE 2013 at 17,8 ft versus Lund 2075 Pro-V SE 2011 at 20,7 ft. Weight tells a clearer story for trailering families: the Lund 2075 Pro-V SE 2011 tips the scales at 1 900 lbs - 550 lbs less than the Lund 1775 Pro-V SE 2013 at 1 350 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 300 hp, the Lund 2075 Pro-V SE 2011 has a 150-hp advantage over the Lund 1775 Pro-V SE 2013's 150-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Lund 2075 Pro-V SE 2011 carries 62 gallons versus 32 gallons in the Lund 1775 Pro-V SE 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 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.
Bottom line: The Lund 2075 Pro-V SE 2011 at 20,7 ft is the right call if deck space, comfort, and entertaining are top of your list. The Lund 1775 Pro-V SE 2013 at 17,8 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
