Heesen Yachts Irisha 2018 vs Heesen Yachts Ultra G 2023 — Same Brand, Different Boat

The Heesen Yachts Irisha 2018 vs Heesen Yachts Ultra G 2023 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 5 500 hp, the Heesen Yachts Ultra G 2023 has a 887-hp advantage over the Heesen Yachts Irisha 2018's 4 613-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 Heesen Yachts Ultra G 2023 is rated for 59 passengers, while the Heesen Yachts Irisha 2018 caps at 51. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Heesen Yachts Ultra G 2023 could be the deciding factor.

Bottom line: Choose the Heesen Yachts Ultra G 2023 if your priority is putting more people on the water — it handles 59 passengers and at 196,1 ft it has the deck room to back that rating up comfortably. The Heesen Yachts Irisha 2018 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 51 that costs less to run day-to-day.

Heesen Yachts Irisha 2018 vs Heesen Yachts Ultra G 2023 — Common Questions

Which is the larger boat — the Heesen Yachts Irisha 2018 or the Heesen Yachts Ultra G 2023?
The Heesen Yachts Ultra G 2023 is the longer of the two at 196,1 feet overall. The Heesen Yachts Irisha 2018 comes in at 167,4 feet, making it roughly 28,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Heesen Yachts Ultra G 2023 is rated to a maximum of 5 500 hp, giving it the larger power ceiling. The Heesen Yachts Irisha 2018 tops out at 4 613 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 Heesen Yachts Irisha 2018 is Coast Guard rated for 51 passengers, while the Heesen Yachts Ultra G 2023 is certified for 59. 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 is wider, and does it affect trailering?
The Heesen Yachts Ultra G 2023 measures 445" wide, compared to 355" for the Heesen Yachts Irisha 2018. 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.
Are the Heesen Yachts Irisha 2018 and Heesen Yachts Ultra G 2023 from the same manufacturer?
Yes — both the Heesen Yachts Irisha 2018 and the Heesen Yachts Ultra G 2023 are built by Heesen Yachts. 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.
