I don't see the wind or wave conditions advancing with time on the route. It appears the predicted weather conditions over the entire route are shown only for the starting time. Actual route planning would show how the weather will change as the vessel proceeds along the route, based on the selected starting time and vessel speed. This should be shown on the one screen without having to mouse along the timeline. An additional feature would be some marks on the route line for a chosen increment of time.
On Route planner, weather conditions are changing along the route according to the time.
The diagram shows the conditions that you will encounter during the trip, "on one screen without having to mouse along the timeline". Or do you get a bug?
The map, of course, shows the weather as forecast for each position of the boat.
At least could you show a screenshot ?
