It is not possible to see the boat before booking it.
However, the Click&Boat internal messaging system allows you to ask all your questions directly to the owner. You can ask the owner to publish more photos on his listing to give you a better idea of the boat.
Click&Boat regularly offers owners the opportunity to improve the attractiveness of their listings and the rental potential of their boats through high definition photos.
The reviews left by renters after a rental are a good indicator of the level of maintenance and comfort of a boat. Don't hesitate to have a look at them!
