Triton Boats 20RX3 2009 vs Triton Boats 21 TRX 2021 — Same Brand, Different Boat

The Triton Boats 20RX3 2009 vs Triton Boats 21 TRX 2021 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.

Both boats share a closely matched power ceiling — 250 hp for the Triton Boats 20RX3 2009 and 250 hp for the Triton Boats 21 TRX 2021. 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. Fuel capacity breaks the other way: the Triton Boats 20RX3 2009 carries 53 gallons versus 47 gallons in the Triton Boats 21 TRX 2021. 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 Triton Boats 20RX3 2009 is rated for 650 passengers, while the Triton Boats 21 TRX 2021 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats 20RX3 2009 could be the deciding factor.

Bottom line: Choose the Triton Boats 20RX3 2009 if your priority is putting more people on the water — it handles 650 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Triton Boats 21 TRX 2021 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
