Take the following as truth: Yachtsmen should bear in mind a Deauville if you can see the port of Le Havre, it will rain in the afternoon, and if you can't, it's already raining.
Then the following statement: "If a Yachtsmen can see the port of Le Havre it will rain in the afternoon, and if you're unable to, it's already raining." is true, false, or inconclusive?
