Luhrs 31 Hardtop 2007 vs Luhrs 35 Convertible 2008 — Same Brand, Different Boat

The Luhrs 31 Hardtop 2007 vs Luhrs 35 Convertible 2008 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.

Size is the most obvious dividing line here. The Luhrs 35 Convertible 2008 measures 38,0 feet overall (2008), giving it roughly 4,0 additional feet of deck space compared to the Luhrs 31 Hardtop 2007 at 34,0 feet (2007). At 135 lbs and 235 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 480 hp, the Luhrs 35 Convertible 2008 has a 100-hp advantage over the Luhrs 31 Hardtop 2007's 380-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 4 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Luhrs 35 Convertible 2008 is rated for 11 passengers, while the Luhrs 31 Hardtop 2007 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Luhrs 35 Convertible 2008 could be the deciding factor.

Bottom line: Choose the Luhrs 35 Convertible 2008 if your priority is putting more people on the water — it handles 11 passengers and at 38,0 ft it has the deck room to back that rating up comfortably. The Luhrs 31 Hardtop 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.

Luhrs 31 Hardtop 2007 vs Luhrs 35 Convertible 2008 — Common Questions

Which is the larger boat — the Luhrs 31 Hardtop 2007 or the Luhrs 35 Convertible 2008?
The Luhrs 35 Convertible 2008 is the longer of the two at 38,0 feet overall. The Luhrs 31 Hardtop 2007 comes in at 34,0 feet, making it roughly 4,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Luhrs 31 Hardtop 2007 or the Luhrs 35 Convertible 2008?
For trailering, the Luhrs 31 Hardtop 2007 has the edge at 135 lbs dry weight versus 235 lbs for the Luhrs 35 Convertible 2008. 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 35 Convertible 2008 is rated to a maximum of 480 hp, giving it the larger power ceiling. The Luhrs 31 Hardtop 2007 tops out at 380 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 Hardtop 2007 is Coast Guard rated for 10 passengers, while the Luhrs 35 Convertible 2008 is certified for 11. 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.
Which boat is wider, and does it affect trailering?
The Luhrs 35 Convertible 2008 measures 174" wide, compared to 142" for the Luhrs 31 Hardtop 2007. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
How do the fuel tanks compare on the Luhrs 31 Hardtop 2007 and Luhrs 35 Convertible 2008?
Both boats carry similar fuel loads — 3 gallons and 4 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 Hardtop 2007 and Luhrs 35 Convertible 2008 from the same manufacturer?
Yes — both the Luhrs 31 Hardtop 2007 and the Luhrs 35 Convertible 2008 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.
