Q: Which is the larger boat — the Triton Boats 1550 SS 2008 or the Triton Boats TR-21X HP 2006?

The Triton Boats TR-21X HP 2006 is the longer of the two at 21,0 feet overall. The Triton Boats 1550 SS 2008 comes in at 15,0 feet, making it roughly 6,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

The Triton Boats TR-21X HP 2006 is rated to a maximum of 250 hp, giving it the larger power ceiling. The Triton Boats 1550 SS 2008 tops out at 25 hp.

The Triton Boats 1550 SS 2008 is Coast Guard rated for 3 passengers, while the Triton Boats TR-21X HP 2006 is certified for 6.

The Triton Boats TR-21X HP 2006 measures 94" wide, compared to 72" for the Triton Boats 1550 SS 2008. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

Yes — both the Triton Boats 1550 SS 2008 and the Triton Boats TR-21X HP 2006 are built by Triton Boats.

The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Triton Boats 1550 SS 2008 vs Triton Boats TR-21X HP 2006 — Same Brand, Different Boat

The Triton Boats 1550 SS 2008 vs Triton Boats TR-21X HP 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.

The power gap is worth calling out. Rated to 250 hp, the Triton Boats TR-21X HP 2006 has a 225-hp advantage over the Triton Boats 1550 SS 2008's 25-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Triton Boats TR-21X HP 2006 is rated for 6 passengers, while the Triton Boats 1550 SS 2008 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Triton Boats TR-21X HP 2006 could be the deciding factor.

Bottom line: Choose the Triton Boats TR-21X HP 2006 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Triton Boats 1550 SS 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
