In my view the domain is good, but it would be difficult to sell. The obvious end user would be a swimming club. I don't think they have a budget for that.
Or you need to find an Olympic organization that would want a generic domain.
The other possibility would be a swimwear shop but most end users would not use a .org in commerce.
It's true that .org is not heavily used in France, they mostly use .fr/.com.
There are French speakers in Canada too. The problem is that the pool of possible buyers for this type of domain is almost nil imho.
Good luck.
