Sea Hunt BX 21 2006 vs Sea Hunt Ultra 235 SE 2018 — Same Brand, Different Boat

The Sea Hunt BX 21 2006 vs Sea Hunt Ultra 235 SE 2018 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 Sea Hunt Ultra 235 SE 2018 has a 50-hp advantage over the Sea Hunt BX 21 2006's 200-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Hunt Ultra 235 SE 2018 carries 98 gallons versus 58 gallons in the Sea Hunt BX 21 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 7 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.

Bottom line: The Sea Hunt Ultra 235 SE 2018 at 23,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Hunt BX 21 2006 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Sea Hunt BX 21 2006 vs Sea Hunt Ultra 235 SE 2018 — Common Questions

Which is the larger boat — the Sea Hunt BX 21 2006 or the Sea Hunt Ultra 235 SE 2018?
The Sea Hunt Ultra 235 SE 2018 is the longer of the two at 23,0 feet overall. The Sea Hunt BX 21 2006 comes in at 2,0 feet, making it roughly 21,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Sea Hunt Ultra 235 SE 2018 is rated to a maximum of 250 hp, giving it the larger power ceiling. The Sea Hunt BX 21 2006 tops out at 200 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 Sea Hunt BX 21 2006 is Coast Guard rated for 7 passengers, while the Sea Hunt Ultra 235 SE 2018 is certified for 7. 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.
Which boat has the larger fuel tank — the Sea Hunt BX 21 2006 or the Sea Hunt Ultra 235 SE 2018?
The Sea Hunt Ultra 235 SE 2018 has the bigger tank at 98 gallons, versus 58 gallons on the Sea Hunt BX 21 2006. That 40-gallon difference translates to roughly 120–200 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Hunt BX 21 2006 and Sea Hunt Ultra 235 SE 2018 from the same manufacturer?
Yes — both the Sea Hunt BX 21 2006 and the Sea Hunt Ultra 235 SE 2018 are built by Sea Hunt. 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.
