When two boats share the same hull type — in this case both the Lund 1648M 2009 and the Lund 1700 Pro Sport Vazer 2008 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?

The power gap is worth calling out. Rated to 100 hp, the Lund 1700 Pro Sport Vazer 2008 has a 65-hp advantage over the Lund 1648M 2009's 35-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 1700 Pro Sport Vazer 2008 is rated for 5 passengers, while the Lund 1648M 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1700 Pro Sport Vazer 2008 could be the deciding factor.
