Q: Which is the larger boat — the Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 or the Caddo Runabout 203 BR OB 2010?

The Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 is the longer of the two at 21,7 feet overall. The Caddo Runabout 203 BR OB 2010 comes in at 20,3 feet, making it roughly 1,4 ft shorter — a meaningful difference in deck room and overall on-water presence.

Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 is Coast Guard rated for 7 passengers, while the Caddo Runabout 203 BR OB 2010 is certified for 8.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 and Caddo Runabout 203 BR OB 2010 share an 102 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.

Q: Which boat has the larger fuel tank — the Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 or the Caddo Runabout 203 BR OB 2010?

The Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 has the bigger tank at 47 gallons, versus 39 gallons on the Caddo Runabout 203 BR OB 2010. That 8-gallon difference translates to roughly 24–40 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 and Caddo Runabout 203 BR OB 2010 from the same manufacturer?

Yes — both the Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 and the Caddo Runabout 203 BR OB 2010 are built by Caddo. 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.

Detailed Evaluation & Buyer Recommendation

Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 vs Caddo Runabout 203 BR OB 2010 — Same Brand, Different Boat

Matching a tunnel Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 against a modified vee Caddo Runabout 203 BR OB 2010 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

The power gap is worth calling out. Rated to 200 hp, the Caddo Runabout 203 BR OB 2010 has a 50-hp advantage over the Caddo Rolled Gunnel 218 OB Tunnel Hull 2010's 150-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 Rolled Gunnel 218 OB Tunnel Hull 2010 carries 47 gallons versus 39 gallons in the Caddo Runabout 203 BR OB 2010. 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 Caddo Runabout 203 BR OB 2010 is rated for 8 passengers, while the Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Caddo Runabout 203 BR OB 2010 could be the deciding factor.

Bottom line: Choose the Caddo Runabout 203 BR OB 2010 if your priority is putting more people on the water — it handles 8 passengers and at 20,3 ft it has the deck room to back that rating up comfortably. The Caddo Rolled Gunnel 218 OB Tunnel Hull 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
