The Lund 1800 Alaskan Tiller 2009 is a modified-V design and the Lund SSV 16 2013 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Lund 1800 Alaskan Tiller 2009 at 18,0 ft versus Lund SSV 16 2013 at 16,0 ft. Weight tells a clearer story for trailering families: the Lund 1800 Alaskan Tiller 2009 tips the scales at 975 lbs - 625 lbs more than the Lund SSV 16 2013 at 350 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 75 hp, the Lund 1800 Alaskan Tiller 2009 has a 35-hp advantage over the Lund SSV 16 2013's 40-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Lund SSV 16 2013 is rated for 6 passengers, while the Lund 1800 Alaskan Tiller 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund SSV 16 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Lund SSV 16 2013 comes in at 9 lbs per hp versus 13 lbs per hp for the Lund 1800 Alaskan Tiller 2009. 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: Choose the Lund SSV 16 2013 if your priority is putting more people on the water - it handles 6 passengers and at 16,0 ft it has the deck room to back that rating up comfortably. The Lund 1800 Alaskan Tiller 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
