Both the Tahoe Boats Q4 SF 2012 and the Tahoe Boats Q4i SF 2013 are modified-V designs, both built in fibreglass, so 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 Q4 SF 2012 at 18,1 ft versus Tahoe Boats Q4i SF 2013 at 18,1 ft. Weight tells a clearer story for trailering families: the Tahoe Boats Q4 SF 2012 tips the scales at 2 270 lbs - 945 lbs more than the Tahoe Boats Q4i SF 2013 at 1 325 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 - 135 hp for the Tahoe Boats Q4 SF 2012 and 135 hp for the Tahoe Boats Q4i SF 2013. 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. Both carry nearly identical fuel loads - 18 gal and 19 gal - so range won't be a tiebreaker here.

Both boats are rated for 8 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.
