If you want to run courses to restore the fitness to drive of drivers who have committed alcohol or drug offences, you need to be recognised by the authority responsible under state law.

If you do not hold a Lake Constance skipper's license, but another skipper's license from a country bordering Lake Constance, you can temporarily obtain a vacation or vacation skipper's license (temporary Lake Constance skipper's license) to operate a boat on Lake Constance. It is valid for 30 days at a stretch within a calendar year and is issued only once a year.

Note: To drive a vessel registered on Lake Constance, you generally need the Bodenseeschifferpatent if

• the ship or boat is operated with an engine and the engine power is more than 4.4 kilowatts
• the sailboat has more than 12 square meters of sail area.

The vessel must have a license or registration for Lake Constance regardless of the temporary Lake Constance skipper's license.

Tip: On the websites of the responsible district offices you will find more information about the:

• Vacationer's patent of the district office Bodenseekreis
• Holidaymaker's license of the Constance District Office

Holders of a driving licence may, on application, extend it to include a further driving licence (class).
