Matching a modified vee Lund 1800 Pro Sport OB 2005 against a deep vee Lund 1950 Tyee 2013 means you're likely deciding between two genuinely 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 1800 Pro Sport OB 2005 at 18,0 ft versus Lund 1950 Tyee 2013 at 19,7 ft. Weight tells a clearer story for trailering families: the Lund 1950 Tyee 2013 tips the scales at 1 735 lbs — 1 607 lbs less than the Lund 1800 Pro Sport OB 2005 at 128 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 225 hp, the Lund 1950 Tyee 2013 has a 75-hp advantage over the Lund 1800 Pro Sport OB 2005's 150-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 1800 Pro Sport OB 2005 carries 32 gallons versus 5 gallons in the Lund 1950 Tyee 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 1950 Tyee 2013 is rated for 9 passengers, while the Lund 1800 Pro Sport OB 2005 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1950 Tyee 2013 could be the deciding factor.
Bottom line: Choose the Lund 1950 Tyee 2013 if your priority is putting more people on the water — it handles 9 passengers and at 19,7 ft it has the deck room to back that rating up comfortably. The Lund 1800 Pro Sport OB 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
