The Caddo Deckliner 183 OB Tunnel Hull 2010 is a tunnel hull design and the Caddo Deckliner 191 IO Vee Hull 2010 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department - Caddo Deckliner 183 OB Tunnel Hull 2010 at 18,3 ft versus Caddo Deckliner 191 IO Vee Hull 2010 at 19,2 ft. Weight tells a clearer story for trailering families: the Caddo Deckliner 191 IO Vee Hull 2010 tips the scales at 3 500 lbs - 300 lbs less than the Caddo Deckliner 183 OB Tunnel Hull 2010 at 3 200 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 225 hp, the Caddo Deckliner 191 IO Vee Hull 2010 has a 75-hp advantage over the Caddo Deckliner 183 OB Tunnel Hull 2010's 150-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 46 gal and 46 gal - so range won't be a tiebreaker here.

Both boats are rated for 7 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.
