I don't really like the name 'Boating' but it seems to be the best collective term for 'self-drive' holidays on the water.
If you want steer your boat through the Scottish lochs, along the French canals, or around the West Indies, the lists of companies who do that, are here.
If, on the other hand, you want someone to bring you a drink while your hotel barge or cruise ship docks, then you're looking for the cruise lists.
Having said that, while the Boating category covers self-drive flotilla sailing holidays in the Mediterranean, motor boats in the Morbihan (Brittany) and narrowboats on the Grand Union canal, I'm also including some lists with 'skippered' as well as 'bareboat' charter companies. So technically 'Boating' covers self-drive & private charter.
There are three general lists...
And two destination-specific lists...
