Odyssey 325C TT I/O 2006 vs Odyssey 725CO-4 Gate 2006: Same Brand, Different Boat

The Odyssey 325C TT I/O 2006 vs Odyssey 725CO-4 Gate 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department - Odyssey 325C TT I/O 2006 at 25,0 ft versus Odyssey 725CO-4 Gate 2006 at 24,0 ft. Weight tells a clearer story for trailering families: the Odyssey 325C TT I/O 2006 tips the scales at 2 870 lbs - 500 lbs more than the Odyssey 725CO-4 Gate 2006 at 2 370 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 300 hp, the Odyssey 325C TT I/O 2006 has a 165-hp advantage over the Odyssey 725CO-4 Gate 2006's 135-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 15 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Odyssey 325C TT I/O 2006 comes in at 10 lbs per hp versus 18 lbs per hp for the Odyssey 725CO-4 Gate 2006. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Both are inflatable designs, which means they pack down for compact storage, can be carried in a bag, and are dramatically lighter than equivalent rigid hulls. The trade-off is setup time and the need to monitor tube pressure regularly.

Bottom line: Performance buyers should lean toward the Odyssey 325C TT I/O 2006 and its 300-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Odyssey 725CO-4 Gate 2006 with its 135-hp rating is the more economical daily driver.

Odyssey 325C TT I/O 2006 vs Odyssey 725CO-4 Gate 2006 - Common Questions

Which is the larger boat - the Odyssey 325C TT I/O 2006 or the Odyssey 725CO-4 Gate 2006?
The Odyssey 325C TT I/O 2006 is the longer of the two at 25,0 feet overall. The Odyssey 725CO-4 Gate 2006 comes in at 24,0 feet, making it roughly 1,0 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Odyssey 325C TT I/O 2006 or the Odyssey 725CO-4 Gate 2006?
For trailering, the Odyssey 725CO-4 Gate 2006 has the edge at 2 370 lbs dry weight versus 2 870 lbs for the Odyssey 325C TT I/O 2006. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Odyssey 325C TT I/O 2006 is rated to a maximum of 300 hp, giving it the larger power ceiling. The Odyssey 725CO-4 Gate 2006 tops out at 135 hp. 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.
How many people can each boat hold?
The Odyssey 325C TT I/O 2006 is Coast Guard rated for 15 passengers, while the Odyssey 725CO-4 Gate 2006 is certified for 15. Note that legal capacity and comfortable capacity aren't always the same thing - on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Odyssey 325C TT I/O 2006 and Odyssey 725CO-4 Gate 2006 share an 8 ft. 6 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.
Are the Odyssey 325C TT I/O 2006 and Odyssey 725CO-4 Gate 2006 from the same manufacturer?
Yes - both the Odyssey 325C TT I/O 2006 and the Odyssey 725CO-4 Gate 2006 are built by Odyssey. 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.
