Both the Lund 1800 Fisherman OB 2006 and the Lund 1825 Pro Guide 2011 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 1800 Fisherman OB 2006 at 18,0 ft versus Lund 1825 Pro Guide 2011 at 18,3 ft. Weight tells a clearer story for trailering families: the Lund 1800 Fisherman OB 2006 tips the scales at 1 475 lbs - 255 lbs more than the Lund 1825 Pro Guide 2011 at 1 220 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 175 hp, the Lund 1800 Fisherman OB 2006 has a 85-hp advantage over the Lund 1825 Pro Guide 2011's 90-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 Fisherman OB 2006 carries 40 gallons versus 32 gallons in the Lund 1825 Pro Guide 2011. 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 1800 Fisherman OB 2006 is rated for 8 passengers, while the Lund 1825 Pro Guide 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1800 Fisherman OB 2006 could be the deciding factor.
