Both the Lund 1600 Alaskan 2005 and the Lund Classic 1775 SS 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 1600 Alaskan 2005 at 16,0 ft versus Lund Classic 1775 SS 2006 at 17,0 ft. At 850 lbs and 950 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.
Both boats share a closely matched power ceiling - 75 hp for the Lund 1600 Alaskan 2005 and 90 hp for the Lund Classic 1775 SS 2006. 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 6 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.
At this size, power-to-weight ratio matters more than outright horsepower. The Lund Classic 1775 SS 2006 comes in at 11 lbs per hp versus 11 lbs per hp for the Lund 1600 Alaskan 2005. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: The Lund 1600 Alaskan 2005 and Lund Classic 1775 SS 2006 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
