Both the Lund 1725 Pro Guide Tiller 2010 and the Lund 2010 Explorer SS 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 1725 Pro Guide Tiller 2010 at 17,3 ft versus Lund 2010 Explorer SS 2011 at 20,2 ft. Weight tells a clearer story for trailering families: the Lund 2010 Explorer SS 2011 tips the scales at 1 700 lbs - 580 lbs less than the Lund 1725 Pro Guide Tiller 2010 at 1 120 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 200 hp, the Lund 2010 Explorer SS 2011 has a 125-hp advantage over the Lund 1725 Pro Guide Tiller 2010's 75-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 2010 Explorer SS 2011 carries 50 gallons versus 27 gallons in the Lund 1725 Pro Guide Tiller 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 2010 Explorer SS 2011 is rated for 6 passengers, while the Lund 1725 Pro Guide Tiller 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 2010 Explorer SS 2011 could be the deciding factor.
Bottom line: Choose the Lund 2010 Explorer SS 2011 if your priority is putting more people on the water - it handles 6 passengers and at 20,2 ft it has the deck room to back that rating up comfortably. The Lund 1725 Pro Guide Tiller 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.
