Excellent, glad to hear you all arrived safely. I haven't yet done Channel Islands by RIB, as I tend to only have the RIB in over winter, but is still on my "to do" list. The afternoon was the best part of the day in Guernsey yesterday - wind significantly dropped after 13:00 or so, and sea state much better. I wanted to go to Herm yesterday afternoon, but got stuck replacing a nav light smashed off by a wayward French charter yacht...!
We'll be sailing back up to Alderney this afternoon, and then wind looks good for a passage back to Poole on Tuesday. Not sure we'll manage sub 5 hours, but 8 hours is reasonable for us!
You should have a much faster and smoother passage back today - have fun.
