The Luhrs 31 Open IPS 2011 is a deep-V design and the Luhrs 36 Open 2008 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.

Size is the most obvious dividing line here. The Luhrs 36 Open 2008 measures 38,0 feet overall (2008), giving it roughly 3,7 additional feet of deck space compared to the Luhrs 31 Open IPS 2011 at 34,3 feet (2011). Weight tells a clearer story for trailering families: the Luhrs 36 Open 2008 tips the scales at 22 000 lbs - 8 500 lbs less than the Luhrs 31 Open IPS 2011 at 13 500 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 500 hp, the Luhrs 36 Open 2008 has a 240-hp advantage over the Luhrs 31 Open IPS 2011's 260-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Luhrs 36 Open 2008 carries 400 gallons versus 300 gallons in the Luhrs 31 Open IPS 2011. 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 Luhrs 36 Open 2008 is rated for 11 passengers, while the Luhrs 31 Open IPS 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Luhrs 36 Open 2008 could be the deciding factor.
