A very nice way to spend a few days -- the epitome of "slow travel", moving at 5 kph, and for a great deal of the time being away from the hustle and bustle of towns and busy roads. The boats are easy enough to handle: about 30-60 minutes' tuition and the application of common sense, and you should be okay.
Emerald Star are cutting back greatly on their Irish operation, but there are other good companies out there also.
A few of us of thinking about a long weekend away and were thinking about hiring a boat for something different. Anyone done it and what did they think?
.. but it would have been nice to visit a pub on our way from Portumna to Carrig on Shannon with some entertainment or life in them.
