When two boats share the same hull type — in this case both the Champion Boats 19 Sea Champ 2006 and the Champion Boats 20 Sea Champ 2006 are modified vee 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?
Size is the most obvious dividing line here. The Champion Boats 19 Sea Champ 2006 measures 18,0 feet overall (2006), giving it roughly 16,0 additional feet of deck space compared to the Champion Boats 20 Sea Champ 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Champion Boats 19 Sea Champ 2006 tips the scales at 175 lbs — 157 lbs more than the Champion Boats 20 Sea Champ 2006 at 18 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.
Both boats share a closely matched power ceiling — 115 hp for the Champion Boats 19 Sea Champ 2006 and 115 hp for the Champion Boats 20 Sea Champ 2006. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 53 gal and 52 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Champion Boats 20 Sea Champ 2006 is rated for 6 passengers, while the Champion Boats 19 Sea Champ 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Champion Boats 20 Sea Champ 2006 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Champion Boats 20 Sea Champ 2006 comes in at 0 lbs per hp versus 2 lbs per hp for the Champion Boats 19 Sea Champ 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.
Bottom line: Choose the Champion Boats 20 Sea Champ 2006 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Champion Boats 19 Sea Champ 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
