Orkney Ferries officers have voted for industrial action in a pay dispute.
The Nautilus International union said its members opted to strike by a "massive majority", with a ballot showing 21 senior staff voting in favour and one against.
The union is willing to meet management for further talks, however.
Nautilus ferry organiser Micky Smyth said: "The ballot results are very clear and reflect the long-running frustration of our members about their pay and conditions.
