When two boats share the same hull type — in this case both the Tahoe Boats Q5i SF 2013 and the Tahoe Boats Q7 SF 2011 are modified vee designs with fiberglass 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 — Tahoe Boats Q5i SF 2013 at 19,4 ft versus Tahoe Boats Q7 SF 2011 at 20,5 ft. Weight tells a clearer story for trailering families: the Tahoe Boats Q5i SF 2013 tips the scales at 2 722 lbs — 2 694 lbs more than the Tahoe Boats Q7 SF 2011 at 28 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 300 hp, the Tahoe Boats Q7 SF 2011 has a 80-hp advantage over the Tahoe Boats Q5i SF 2013's 220-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Tahoe Boats Q7 SF 2011 carries 45 gallons versus 19 gallons in the Tahoe Boats Q5i SF 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Tahoe Boats Q7 SF 2011 is rated for 9 passengers, while the Tahoe Boats Q5i SF 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Tahoe Boats Q7 SF 2011 could be the deciding factor.
