When two boats share the same hull type — in this case both the Lund 1600 Pro Sport OB 2005 and the Lund Classic 1625 Tiller 2006 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 1600 Pro Sport OB 2005 at 16,0 ft versus Lund Classic 1625 Tiller 2006 at 16,0 ft. Weight tells a clearer story for trailering families: the Lund 1600 Pro Sport OB 2005 tips the scales at 971 lbs — 908 lbs more than the Lund Classic 1625 Tiller 2006 at 63 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 90 hp, the Lund 1600 Pro Sport OB 2005 has a 50-hp advantage over the Lund Classic 1625 Tiller 2006's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

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.

At this size, power-to-weight ratio matters more than outright horsepower. The Lund Classic 1625 Tiller 2006 comes in at 2 lbs per hp versus 11 lbs per hp for the Lund 1600 Pro Sport OB 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.
