Due to the forecast the NorthLink ferry Hrossey headed down to Orkney and onwards to Aberdeen about 2 and half hours early. It made good time at over 20 knots for most of the first leg of the trip. Looking at heavy seas the rest of the weekend so probably no boats north or south tomorrow night.
The ferry is passing the Bressay Lighthouse at this point about 20 minutes into the trip which is about where any calm waters will have ended.
