'Cruising Scotland, the Clyde to Cape Wrath: a companion to the Clyde Cruising Club Sailing Directions'. Mike Balmforth and Edward Mason, Clyde Cruising Club Publications, 2010 published by Imray. This lavishly illustrated book celebrates the centenary of the Clyde Cruising Club with a description of many of the places on this website, and more — the whole of the west coast in fact. For the coffee table as well as the boat library.
'Pevsner' is my generic term for all those wonderfully detailed books about the buildings of England, Scotland, Ireland and Wales, which were started by Nikolaus Pevsner, the architectural historian, and first published between 1951 and 1974. The two volumes you need for this area are 'Argyll and Bute' by Frank Arneil Walker, Penguin Books 1992, and 'Highlands and Islands' by John Gifford, Yale University press, 2003.
'The Scottish Islands'. Hamish Haswell-Smith, Canongate, Edinburgh, revised and updated 2015, is the bible for these parts, albeit not by definition for the mainland of Scotland. The drawings, by the architect author, are charming and the information encyclopaedic. It has to be on the boat really. Alas here will be no more updates as the author died in 2019.
'Scotland the Best'. Peter Irvine, Collins, Glasgow, 2019, now in its 13th edition, is quite simply the best guide to Scotland — beaches, walks, pubs, hotels, everything. It is specific rather than sensitive as we say in the medical trade. In other words there are some good places missing but those that are included are almost invariably excellent. I have mentioned nearly everywhere that is listed in the guide if it is within reach of an anchorage.
