An international competition involving small boats called skiffs is set to begin at Ullapool.
The St Ayles Skiff World Championships in Loch Broom will run until Sunday.
St Ayles skiffs are rowing boats measuring 22ft long and 5ft 6in in breadth and built to the design of a traditional Fair Isle skiff.
Enthusiasts can buy the craft in a kit form. Boats entered include one from the US that doubles as a musical instrument.
The Sephira, also known as the Musical Ark, was constructed by staff and students at Moravian Academy in Bethlehem, Pennsylvania.
