The Bavaria Yachts E34 Fly 2017 vs Bavaria Yachts S40 HT Hard Top 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 370 hp, the Bavaria Yachts S40 HT Hard Top 2018 has a 150-hp advantage over the Bavaria Yachts E34 Fly 2017's 220-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Bavaria Yachts S40 HT Hard Top 2018 carries 198 gallons versus 79 gallons in the Bavaria Yachts E34 Fly 2017. 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 Bavaria Yachts S40 HT Hard Top 2018 is rated for 12 passengers, while the Bavaria Yachts E34 Fly 2017 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bavaria Yachts S40 HT Hard Top 2018 could be the deciding factor.
Bottom line: Choose the Bavaria Yachts S40 HT Hard Top 2018 if your priority is putting more people on the water — it handles 12 passengers and at 40,1 ft it has the deck room to back that rating up comfortably. The Bavaria Yachts E34 Fly 2017 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
