When two boats share the same hull type — in this case both the Caddo BayStealth 1880 OB Tunnel Hull 2010 and the Caddo Rolled Gunnel 173 OB Tunnel Hull 2010 are tunnel designs with composite 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 150 hp, the Caddo BayStealth 1880 OB Tunnel Hull 2010 has a 35-hp advantage over the Caddo Rolled Gunnel 173 OB Tunnel Hull 2010's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Caddo BayStealth 1880 OB Tunnel Hull 2010 carries 46 gallons versus 31 gallons in the Caddo Rolled Gunnel 173 OB Tunnel Hull 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 6 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.
