Lake Constance (Untersee!!): Private & guided Boat Tour

The best thing about this Lake Constance boat tour is its setting: the Untersee is calmer and more intimate than the larger eastern part of the lake. You cruise aboard a polished Sea Ray SPXE190, stopping your way for views, sun, or a swim rather than following a rigid sightseeing script. I like the private format and the fact that a skipper handles the 200-horsepower motor while you simply enjoy the water.

I also like the generous bow lounge for sunbathing and the broad stern platform made for easy swims. The main consideration is the two-hour limit. That is enough for a pleasant outing, but not a full-day cruise, and there is no toilet on board. A harbor stop can be arranged if needed.

Key points at a glance

• The Untersee setting: A quieter part of Lake Constance with calm cruising and attractive natural views.
• A private Sea Ray for up to five: Your group gets the whole boat, rather than sharing space with strangers.
• A flexible two-hour plan: Use the time for cruising, sightseeing, sunbathing, swimming, or a mix of all four.
• A 200 PS MerCruiser engine: The boat has plenty of power, while the skipper manages the driving and safety.
• Swimming from the stern platform: The rear of the boat makes getting into and out of the lake simple.
• Pickup from Gaienhofen-Horn: Regional German or Swiss harbor pickup is possible in the Untersee area for an added charge.

Why the Untersee makes a better boat outing

Lake Constance is large enough to feel different from one shore to the next. The Untersee, at the western end, has a quieter character than the busier eastern section. This tour uses that calmer setting well, giving you two hours on the water without the feel of a crowded group excursion.

You are not signing up for a fixed list of monuments or timed stops. The value is the setting itself: open water, shore views, small coves, and the chance to slow down. If you want a boat ride that feels personal rather than packaged, this format makes sense.

The tour begins at the harbor in Gaienhofen-Horn. Pickup is at the end of the landing stage, so you should contact the provider ahead of time to make sure you meet at the right point. Pickup from another harbor in the German or Swiss Untersee area is possible, but it costs extra.

Boarding the Sea Ray SPXE190

The boat is a Sea Ray SPXE190 bowrider, a compact but stylish motorboat designed for relaxed time on the water. It holds up to five people, which is an important limit to remember. This is best for a small family, a couple with friends, or a group that wants a private outing without filling a large tour boat.

The bow has a lounge area where you can sit back or sunbathe while the boat is moving. At the stern, a large swim platform gives you a practical place to sit before and after getting into the lake. Those two areas give the boat different moods: the front for watching the shoreline and feeling the breeze, the back for water time.

The 200 PS MerCruiser inboard motor gives the Sea Ray strong performance. You do not need to know anything about operating a boat, and you are not expected to handle the controls. The skipper takes care of driving, navigation, and safety, leaving you free to enjoy the ride.

Shoes are not allowed on board, so wear something easy to remove. Pets are also not permitted. These rules are simple, but knowing them in advance helps you arrive prepared.

How your two hours can unfold

This is not a tour with a set route published in advance. The private format lets you shape the outing around your group, which is one of its strongest features.

You might begin with a period of steady cruising, using the first part of the ride to enjoy the Untersee from the water. The view changes as you move, and a boat gives you a different angle on the shoreline than a road or walking path. If sightseeing is your priority, tell the skipper before setting out so the route can reflect that.

You can also make the outing mostly about relaxation. The bow lounge is suited to sitting in the sun, and you can ask to visit a quiet cove for sunbathing. This works well if you have already spent days touring towns and want a slower break.

Swimming is another central option. The stern platform is built for water access, so you can use part of the trip for a refreshing bath in the lake. The exact amount of swimming time depends on your plan and the conditions, but the skipper can adjust the outing around your wishes.

Most groups will probably want a combination: cruise first, stop for a swim, then spend the remaining time floating, drying off, or returning through the scenery. With only two hours, I would decide before boarding which activity matters most. Trying to fit too many separate aims into a short trip can make the outing feel rushed.

The boat is supplied with bottled water. Food is not included, and alcoholic drinks are available only by advance order. If you want refreshments beyond water, arrange them before departure rather than assuming you can buy them on board.

What the skipper adds

The skipper is more than a person at the wheel. On a private motorboat, good judgment affects the whole mood of the trip. The skipper provides attentive service, manages the powerful engine, and keeps the ride comfortable and safe.

The operator offers service in German, English, and French. That makes the tour easier to arrange for an international group, especially when you want to explain whether you prefer sightseeing, swimming, or a quiet cruise.

Nicole, the host named in the booking information, is described as flexible with timing when weather conditions changed. That matters on a boat tour, where a small shift in weather can affect comfort. The ability to adjust the departure time helped one group of four choose a better-weather period on the same day.

That flexibility should not be confused with a guarantee of unlimited changes. Contact the provider if conditions are poor or your schedule shifts. The published cancellation policy allows a full refund when you cancel at least 24 hours ahead.

Swimming, sunbathing, and the no-toilet issue

The boat is well suited to a warm-weather outing centered on the lake. The bow lounge gives you room to stretch out, and the stern platform makes swimming more convenient than climbing over a side rail.

Still, you should plan around the boat’s limits. There is no toilet on board. A harbor stop can be made if necessary, but you should use facilities before departure and avoid treating this as a boat with full onboard amenities.

There is also no food included. Bring this into your planning if you are booking around lunch or dinner, while remembering that any drinks beyond bottled water need to be arranged in advance. The experience is about the boat and the lake, not onboard dining.

The tour is not suitable for children under two or for people prone to seasickness. Even a smooth lake can feel uncomfortable for someone sensitive to motion. If that is a concern in your group, the short duration may help, but the provider specifically lists seasickness as a reason this activity may not be suitable.

Is $363 good value for a private boat?

The price is $363 for a private group of up to five people. At full capacity, that works out to about $72.60 per person for two hours, including the skipper, fuel, bottled water, and pickup from Gaienhofen-Horn.

That is not a bargain-priced public boat ride, but it is a different product. You are paying for privacy, a high-quality boat, a professional skipper, and control over how the time is used. For five people, the per-person cost is easier to justify. For two people, the same fixed price feels much steeper.

Fuel is included, which is useful because the boat’s 200 PS motor could otherwise make pricing less predictable. You also avoid the work and responsibility of renting and operating the boat yourself. For a special afternoon, a family outing, or a small celebration, those details add real value.

The value drops if you want a long cruise or a structured sightseeing program. Two hours passes quickly, particularly if you want both sightseeing and a substantial swim. Compare this tour with a standard public cruise if your main goal is simply to be on Lake Constance for as long as possible at the lowest cost.

Who will enjoy this boat trip most?

I would recommend this tour most strongly to people who value privacy and flexibility. A group of friends can build the outing around swimming and sun, while a family can choose a gentler cruise with time to look at the shore.

It is also a good fit for couples who want a polished, quiet boat ride rather than a large shared vessel. The boat’s design gives you places to sit together, and the skipper can adapt the outing instead of following a fixed narration.

This is less suitable for anyone seeking a detailed historical tour. The information provided focuses on cruising, scenery, swimming, and relaxation. If you want constant commentary about towns, architecture, or local history, ask the provider how much guiding is planned before you book.

The five-person maximum also matters. A larger family or group cannot simply add another person. For the right-sized group, though, the limit is exactly what keeps the outing private and comfortable.

Weather and timing matter more than usual

A boat trip depends on conditions, and comfort can change quickly with sun, wind, or rain. The flexible scheduling offered by the host is helpful, especially for visitors with some room in their itinerary.

If you have several possible times available, ask about the best departure window rather than choosing blindly. A group of four was able to shift its time on the day to find better weather, which shows why it pays to communicate with the provider.

The boat trip lasts two hours, with starting times based on availability. I would avoid booking it as the final activity before a train, meal reservation, or long drive unless you leave plenty of time. Harbor pickup sounds simple, but you still need time to find the landing stage and contact the skipper if you are unsure where to meet.

Practical planning before you book

Wear swimwear beneath comfortable clothes if you plan to use the lake. Since shoes are not allowed, choose clothing and bags that are easy to manage barefoot. The information does not specify storage space, so avoid bringing more than you need.

Bring sun protection, though the boat’s exact shade arrangements are not specified. Bottled water is provided, but food is not. Alcoholic drinks can be ordered ahead, but they are not included.

Confirm the harbor location before the day of the trip. Standard pickup is from Gaienhofen-Horn, while another harbor in the Untersee region may involve a surcharge. The provider asks you to use the listed phone number, 0049 1514 4933300, to make sure you and the skipper find each other.

You can reserve now and pay later, which helps if you are still arranging the rest of your plans. Cancellation is free up to 24 hours in advance for a full refund.

Should you book the Untersee boat tour?

Book it if you have up to five people, want a private boat, and care more about personal time on the water than a long, scripted sightseeing route. The strongest reasons are the calm Untersee setting, the polished Sea Ray, the attentive skipper, and the freedom to choose between cruising, sunbathing, and swimming.

Think twice if you need a toilet on board, want included meals, dislike boat motion, or hope to spend most of the day on the lake. The $363 price makes the most sense when shared by four or five people and when you treat the outing as a special two-hour break.

For a small group looking for an easy, flexible afternoon at Lake Constance, this is a strong choice. Just arrive ready to go barefoot, keep your plans focused, and decide in advance whether the priority is sightseeing, swimming, or simply enjoying the Untersee from a very comfortable boat.
