The Bavaria Yachts S30 Open Open 2015 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.
Both boats share a closely matched power ceiling — 350 hp for the Bavaria Yachts S30 Open Open 2015 and 370 hp for the Bavaria Yachts S40 HT Hard Top 2018. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Bavaria Yachts S40 HT Hard Top 2018 carries 198 gallons versus 137 gallons in the Bavaria Yachts S30 Open Open 2015. 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 S30 Open Open 2015 caps at 8. 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 S30 Open Open 2015 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
