What this means for your charter
Rain or cloud
Charters go ahead. The boat has a full soft-top cover and side windows, and the lake is often at its most atmospheric.
Storms and strong wind
The captain decides 30 minutes before departure. If it is unsafe, the charter is cancelled and fully refunded.
Swimming
On cruises of two hours or more, when the water, the weather and the traffic allow. Best from July to early September.
