Have to agree with Bruce on this one. To my knowledge this sort of thing has been talked about regularly in the 29 years I've lived in the area. Don't make the mistake of thinking that the local council is in any way forward looking, thinking about the success of the town - except for the bit that they (the councillors) own, or care a jot about what the local people want.
You've only got to see what they've done to the thriving airport since they 'took it over - or back' again. Banana republic comes to mind.
Something might happen, there may be a pontoon for a while - like there was many years ago, but it'll soon disappear like the other one did, or break up in a northwesterly.
The thinking at the time of the 'town fathers' about the other initiative was that yachtsmen were no real asset to the town, after all, they bring their food with them and don't spend anything and all those masts make a dreadful noise in the wind. Better off with coaches full of senior citizens. They spend a fortune in McTavish's.... er. Oh dear, that's closed down. Still, without them the hotels wouldn't be able to serve Christmas dinners in November.
If you're in a boat, Oban's a great place to sail past.

There, that feels better. PS As Bruce says, they're thinking about sailing boats and I suppose, so was I really.
