When two boats share the same hull type — in this case both the Lund 1648M 2008 and the Lund 1950 Tyee Gran Sport 2009 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?
Size is the most obvious dividing line here. The Lund 1950 Tyee Gran Sport 2009 measures 19,0 feet overall (2009), giving it roughly 4,0 additional feet of deck space compared to the Lund 1648M 2008 at 15,0 feet (2008). At 42 lbs and 19 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.
The power gap is worth calling out. Rated to 225 hp, the Lund 1950 Tyee Gran Sport 2009 has a 190-hp advantage over the Lund 1648M 2008'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 1950 Tyee Gran Sport 2009 is rated for 5 passengers, while the Lund 1648M 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lund 1950 Tyee Gran Sport 2009 could be the deciding factor.
Bottom line: Choose the Lund 1950 Tyee Gran Sport 2009 if your priority is putting more people on the water — it handles 5 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Lund 1648M 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
