Lurssen Yachts A+ Ex Topaz 2012 vs Lurssen Yachts Amadea 2017 — Same Brand, Different Boat

The Lurssen Yachts A+ Ex Topaz 2012 vs Lurssen Yachts Amadea 2017 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 7 990 hp, the Lurssen Yachts A+ Ex Topaz 2012 has a 2 224-hp advantage over the Lurssen Yachts Amadea 2017's 5 766-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 Lurssen Yachts A+ Ex Topaz 2012 is rated for 147 passengers, while the Lurssen Yachts Amadea 2017 caps at 106. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lurssen Yachts A+ Ex Topaz 2012 could be the deciding factor.

Bottom line: Choose the Lurssen Yachts A+ Ex Topaz 2012 if your priority is putting more people on the water — it handles 147 passengers and at 483,2 ft it has the deck room to back that rating up comfortably. The Lurssen Yachts Amadea 2017 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 106 that costs less to run day-to-day.

The Lurssen Yachts A+ Ex Topaz 2012 is Coast Guard rated for 147 passengers, while the Lurssen Yachts Amadea 2017 is certified for 106.
