Will she sail or won't she?

I suddenly realised on Thursday that I needed to do a refresher course on Crew Resource Management before the end of the month or I wouldn't be eligible to fly. Thankfully a course was available on Monday,but all the flights are booked up and I will have to go by ferry. No hardship - I quite like a trip on the boat. But today the forecast is for high winds and the website says disruption is likely. I walk the dog and see the ferry. Will she sail later with me on it? Or will I be left floundering on the wrong side of the Minch?
