Luhrs 31 Open 2007 vs Luhrs 31 Open IPS 2011 — Same Brand, Different Boat

The Luhrs 31 Open 2007 vs Luhrs 31 Open IPS 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Luhrs 31 Open 2007 at 34,0 ft versus Luhrs 31 Open IPS 2011 at 34,3 ft. At 135 lbs and 135 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 380 hp, the Luhrs 31 Open 2007 has a 120-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. Both carry nearly identical fuel loads — 3 gal and 3 gal — so range won't be a tiebreaker here.

Both boats are rated for 10 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: Performance buyers should lean toward the Luhrs 31 Open 2007 and its 380-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Luhrs 31 Open IPS 2011 with its 260-hp rating is the more economical daily driver.

Luhrs 31 Open 2007 vs Luhrs 31 Open IPS 2011 — Common Questions

Which is the larger boat — the Luhrs 31 Open 2007 or the Luhrs 31 Open IPS 2011?
The Luhrs 31 Open IPS 2011 is the longer of the two at 34,3 feet overall. The Luhrs 31 Open 2007 comes in at 34,0 feet, making it roughly 0,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Luhrs 31 Open 2007 or the Luhrs 31 Open IPS 2011?
For trailering, the Luhrs 31 Open IPS 2011 has the edge at 135 lbs dry weight versus 135 lbs for the Luhrs 31 Open 2007. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Luhrs 31 Open 2007 is rated to a maximum of 380 hp, giving it the larger power ceiling. The Luhrs 31 Open IPS 2011 tops out at 260 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Luhrs 31 Open 2007 is Coast Guard rated for 10 passengers, while the Luhrs 31 Open IPS 2011 is certified for 10. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Luhrs 31 Open 2007 and Luhrs 31 Open IPS 2011 share an 11 ft. 10 in. (3.61 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Luhrs 31 Open 2007 and Luhrs 31 Open IPS 2011?
Both boats carry similar fuel loads — 3 gallons and 3 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Luhrs 31 Open 2007 and Luhrs 31 Open IPS 2011 from the same manufacturer?
Yes — both the Luhrs 31 Open 2007 and the Luhrs 31 Open IPS 2011 are built by Luhrs. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
