There was an exception to this early Scottish refusal to demark the firth as a separate body: the island of Lismore, Scotland (not to be confused with the various Irish Lismores), blocks the entry to Loch Linnhe in such a way as to create a shelter from weather in the Firth of Lorn. In 1816 the commissioners appointed by the British government to complete the Caledonian Canal reported that ships of 300-400 tons were running into Linnhè Loch to shelter from the weather in the firth. The loch was recognized far earlier, but not under that name. Some crown-sponsored sailing directions by a pilot, Alexandre Lindsay, who navigated for James V of Scotland on his voyage around Scotland in 1535, have survived in French from 1583. The book suggests legs for transit of the vessels of the time down the west coast of Scotland, being careful to avoid dangerous waters, which it also lists. From Ardnamurchan one sails WSW to Lismore, Scotland, necessarily in that direction through the Sound of Mull.
