When two boats share the same hull type — in this case both the Lund 1625 Classic SS 2007 and the Lund SSV 18 Tiller 2007 are modified vee designs with aluminum construction — 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 1625 Classic SS 2007 at 16,0 ft versus Lund SSV 18 Tiller 2007 at 18,0 ft. Weight tells a clearer story for trailering families: the Lund 1625 Classic SS 2007 tips the scales at 665 lbs — 619 lbs more than the Lund SSV 18 Tiller 2007 at 46 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 — 40 hp for the Lund 1625 Classic SS 2007 and 60 hp for the Lund SSV 18 Tiller 2007. 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.

For family outings this is probably the sharpest distinction between the two. The Lund SSV 18 Tiller 2007 is rated for 5 passengers, while the Lund 1625 Classic SS 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund SSV 18 Tiller 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Lund SSV 18 Tiller 2007 comes in at 1 lbs per hp versus 17 lbs per hp for the Lund 1625 Classic SS 2007. 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.
