The MV Loch Buie, Loch Buidhe in Gaelic, is the perfect design for the busy passenger crossing from Mull to Iona. The lounge has windows on all sides - designed so you can see as much of the short, scenic crossing as possible. When you're not looking out for seals and seabirds on the crossing, have a look at the wheelhouse: it's painted like a CalMac funnel.
