Both the Lund 1800 Sport Angler 2011 and the Lund 2010 Pro Guide 2007 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 Sport Angler 2011 at 18,5 ft versus Lund 2010 Pro Guide 2007 at 20,0 ft. At 1 460 lbs and 1 440 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 175 hp, the Lund 1800 Sport Angler 2011 has a 60-hp advantage over the Lund 2010 Pro Guide 2007's 115-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 41 gal and 40 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Lund 2010 Pro Guide 2007 is rated for 6 passengers, while the Lund 1800 Sport Angler 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 2010 Pro Guide 2007 could be the deciding factor.
Bottom line: Choose the Lund 2010 Pro Guide 2007 if your priority is putting more people on the water - it handles 6 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Lund 1800 Sport Angler 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
