Both the Lund 1675 Explorer Sport 2011 and the Lund 1800 Alaskan 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 1675 Explorer Sport 2011 at 16,7 ft versus Lund 1800 Alaskan SS 2011 at 18,8 ft. Weight tells a clearer story for trailering families: the Lund 1675 Explorer Sport 2011 tips the scales at 1 190 lbs - 160 lbs more than the Lund 1800 Alaskan SS 2011 at 1 030 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.
Both boats share a closely matched power ceiling - 90 hp for the Lund 1675 Explorer Sport 2011 and 90 hp for the Lund 1800 Alaskan SS 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 19 gal and 19 gal - so range won't be a tiebreaker here.
Both boats are rated for 5 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Lund 1800 Alaskan SS 2011 at 18,8 ft is the right call if deck space, comfort, and entertaining are top of your list. The Lund 1675 Explorer Sport 2011 at 16,7 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
