Calmac Ferry to Bute

This was calculated using the summed sequential ’Vincenty’ (ellipsoid) great circle distances[1] in R, grouped by MMSI with data.tables.

Given the advertised ferry travels on https://www.calmac.co.uk these are realistic calculations, given that Coruisk is a replacement ferry for Bute and Argyle and the Loch Shira does > 25 travels in winter, with the odd replacement from other ferries.
