Luhrs 28 Open 2009 vs Luhrs 31 Hardtop 2007 — Same Brand, Different Boat

The Luhrs 28 Open 2009 vs Luhrs 31 Hardtop 2007 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 28 Open 2009 at 31,0 ft versus Luhrs 31 Hardtop 2007 at 34,0 ft. Weight tells a clearer story for trailering families: the Luhrs 31 Hardtop 2007 tips the scales at 135 lbs — 134 lbs less than the Luhrs 28 Open 2009 at 1 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 Luhrs 31 Hardtop 2007 tops out at 380 hp. Engine specs for the Luhrs 28 Open 2009 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 3 gal and 3 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Luhrs 31 Hardtop 2007 is rated for 10 passengers, while the Luhrs 28 Open 2009 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Luhrs 31 Hardtop 2007 could be the deciding factor.

Bottom line: Choose the Luhrs 31 Hardtop 2007 if your priority is putting more people on the water — it handles 10 passengers and at 34,0 ft it has the deck room to back that rating up comfortably. The Luhrs 28 Open 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
