A travelling rainbow, spotted from the Islay ferry MV Hebridean Isles. As spray was blown up from the bow wave a short rainbow appeared, an unexpected view.

I’ve only seen it once but I believe it is a regular practice. This is the Fast Rescue Craft being lifted up after an exercise in West Loch Tarbert by the Islay ferry MV Hebridean Isles.
Update/correction: Originally I had described the boat as a tender, the correct term is Fast Rescue Craft. Thanks to Jim MacLean for the correction.
