Both the Lund 1850 Tyee 2010 and the Lund 2000 Fisherman OB 2006 are modified-V designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department - Lund 1850 Tyee 2010 at 18,5 ft versus Lund 2000 Fisherman OB 2006 at 19,0 ft. Weight tells a clearer story for trailering families: the Lund 2000 Fisherman OB 2006 tips the scales at 1 730 lbs - 200 lbs less than the Lund 1850 Tyee 2010 at 1 530 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 2000 Fisherman OB 2006 has a 25-hp advantage over the Lund 1850 Tyee 2010's 200-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 2000 Fisherman OB 2006 carries 55 gallons versus 40 gallons in the Lund 1850 Tyee 2010. 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 2000 Fisherman OB 2006 is rated for 10 passengers, while the Lund 1850 Tyee 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 2000 Fisherman OB 2006 could be the deciding factor.
Bottom line: Choose the Lund 2000 Fisherman OB 2006 if your priority is putting more people on the water - it handles 10 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Lund 1850 Tyee 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
