Caledonian
The ‘Caley’, as it is known will save you approximately 250 to 500 miles depending on the number of stops. The benefit comes not only from the shorter distance; but it is also more sheltered, though the wind can be funnelled down the glens, which results.
Crinan
At just 9 miles long, it is the shortest canal and is described as Scotland’s prettiest short cut. The canal crosses mid Argyll, from Ardrishaig, Loch Fyne and emerges at Crinan, allowing you to miss out the Mull of Kintyre, which is known for its strong tides.
Forth and Forth
The restored canal reopened in 2001, and connects the Firths of Clyde and Forth. This route takes you through large towns with busy areas and also peaceful countryside and passes the Falkirk Wheel, the first rotating boat lift. You will need to unstep your mast for this route.
If you use one of the canals, not only do they provide short cuts, but they provide a break, in terms of a different pace and time to just enjoy the scenery. Remember canals are fresh water so you will need to add 10cm to your draft.
