In case of drought alert

The drought alert does not prevent you to navigate. It only needs a heightened attention. Carefully follow the instruction given during your training, especially regarding the more “technical” parts of the river that will be described to you. Follow with precision the navigation channel drawn on the navigation map on board.

In the event of a serious drought, some portions of the river can develop cyanobacterias (the water then takes a bright green color). It is then advised, or sometime even forbidden to swim and do activities such as kayak, paddle, etc … Moreover, it is advised to properly wash yourself anytime you get in contact with water.

Drought can also results in lock passage restriction in some areas when the water level are too low. In that case, the lock keepers will gather several boat at once : you can expect to wait a little bit at some locks. It is advised in that case to communicate with lock keepers and other crews to anticipate the locks to avoid any wait.

In case of high water level alert

The high water level alert do not prevent you from navigating either. It only asks a heightened attention, mostly due to the force of current.

Carefully prepare in advance all your manoeuvers to dock or go through a lock. A maximum amount of crew members should be correctly positioned to help you protect the boat and handle the ropes quickly.

As it will be explained during your training : you should absolutely do your docking manoeuvers against the current (turn around if necessary). The safety jacket is very much advised when you are navigating through a strong current. Children supervision also needs to be reinforced.

Go through a lock autonomously

Depending on the time of the year, it is possible that part of or all the locks needs to be done autonomously (you handle the lock by yourselves). Like said before, if you are navigating at a time of the year where locks are done autonomously, we advise to make sure that the crew is able :

  • Have at least two people in good physical condition
  • In case you embark young children that need constant watch, make sure to have enough crew members to do the surveillance while two others are focused on doing the lock

Do not hesitate, in doubt, to reach us : we will know how to estimate the capability for any specific crews.

Here are a few tips to form a true crew :

  • Share our online boat hire course (click here to see the webpage) to the whole crew and invite them to take the test

  • Communicate during your manoeuvers ; why not choose a head navigator / captain to coordinate everyone ?
