Lots of info on the WI website:
- for boat owners (with links to lots of other pages)
- for businesses. I am sure it will be useful for Waterways Ireland to have a list of businesses, especially those operating on its navigations and property.
I liked the bit on this page:
Enforcement
Boats in non-compliance with the bye-laws will enter an enforcement process. Enforcement is undertaken by Authorised Officers and will begin with a notification in the form of a sticker and if non-compliance continues may result in the craft being removed from the navigation at the owners cost.
I wonder about investing in a crane company.

i’m considering the sticker business.
