We are building an new skilake near Vienna/Austria.
Is there any Information on safety distances, such as slalom buoy to shore, boat turn radius at ends, ramp to shore, etc. available?
Layout see: https://sketchfab.com/3d-models/skipark-2021-01-17-a0024e9d98654333ad8a01cc7e0bd595
Thank you

Our club lake is 250 feet wide by 2150 feet long. We have a jump and the clearances are sufficient to shore.

The boat turn radius is about 130-140 feet (260 feet diameter) at one end and about 100-120 feet (about 210 feet diameter) on the other end. Using the smaller radius end to spin the skier and continue for another pass is really for expert drivers and skiers only, especially since the starting dock is on that already smaller end. I would probably recommend a bit more radius overall - like 150 feet of radius (300 feet diameter).

For slalom buoy distance to shore, I would think you need about 75 feet to provide a safety buffer for novices and beginners who might not have as much control on the water as others. For experienced skiers, you can probably have a little less distance to shore.

Others may have more information or recommendations, but these are the characteristics and observations from our site.

Good luck.

Thank you very much, is there a chance to see your site at google-maps/earth?

By the way, if you click in the lower left corner of Google Earth on the year indicator (e.g., 1992), it will give you a slider control in the upper left to select and view pictures of different years. There is at least one (from 2016) that will show the jump installed. You can use the measure tools in Google Earth to get distances.

@SkiparksKurt Click on the BOS Home drop down menu and look for Google Earth. Click on the link and it will bring you to Google Earth with pinned ski lakes all over the world.

Nice looking design! What are the approximate dimensions of your lake? I am assuming your will be building from scratch or is there a body of water existing and you are going to expand/revitalize it?

Have a look at some of the UK ski lakes, they are all small. Thorpe Park is a good one 51.40283892426805, -0.5178079090601809 as you can see the jump and course

I'd also add, do you have an Austrian Water Ski Association? If not there is the IWWF and the BWSW in the UK. Get in contact with them and they will have the requirements for tournament level ski lakes and usually assist you in planning, regulation approval etc

the new lake is beeing digged from scratch and about 30% ready by now. skiing start will not be before 2022. See google-earth 48°19'47.16"N 16° 1'42.14"E. Lenght is 630m or 2066 ft. Did not get many information from the austrian waterski federation, will try IWWF.

One thought from someone who is NOT an expert: if the cost isn't prohibitive, and the space allows it, go longer, maybe 2400 feet. This allows a bit more setup time for both skier and driver and is a bit more friendly to recreational skiing and (am I really saying this?) wakeboarding.

Another thing to consider is weed propagation, wave wash back, water depth, and max water temperature. Our lake is 2000’ by 240’ wide. We do not jump on our lake. For skiing the width we have is definitely wide enough - I’m not sure about jumping. I’d rely on those that have experience with jumping.

I really love the 3D concept of your lake. You certainly put some thought into this and it shows. Besides safety aspects of a purpose built ski/jump lake do you have any other questions? Feel free to PM me with any other questions.
