Q: How many people can each boat hold?

The Tahoe Boats Q3 SF I/O 2003 is Coast Guard rated for 7 passengers, while the Tahoe Boats Q4 SS 2008 is certified for 8.

Both the Tahoe Boats Q3 SF I/O 2003 and Tahoe Boats Q4 SS 2008 share an 90.5 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads.

The Tahoe Boats Q3 SF I/O 2003 has the bigger tank at 23 gallons, versus 2 gallons on the Tahoe Boats Q4 SS 2008. That 21-gallon difference translates to roughly 63–105 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes — both the Tahoe Boats Q3 SF I/O 2003 and the Tahoe Boats Q4 SS 2008 are built by Tahoe Boats. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
