The Lund 1675 Impact Sport 2013 is a deep-V design and the Lund 1775 Impact SS 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 1675 Impact Sport 2013 at 16,8 ft versus Lund 1775 Impact SS 2011 at 17,8 ft. At 1 125 lbs and 1 170 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 125 hp, the Lund 1775 Impact SS 2011 has a 35-hp advantage over the Lund 1675 Impact Sport 2013's 90-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 1775 Impact SS 2011 carries 27 gallons versus 19 gallons in the Lund 1675 Impact Sport 2013. 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 Lund 1675 Impact Sport 2013 is rated for 6 passengers, while the Lund 1775 Impact SS 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1675 Impact Sport 2013 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Lund 1775 Impact SS 2011 comes in at 9 lbs per hp versus 13 lbs per hp for the Lund 1675 Impact Sport 2013. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
