If you are buying a new boat from Mothership Marine you will probably want us to paint your ‘index number’ in the colour scheme of the boat. In order to do this you need to sign up to the Canal and River Trust online licensing portal. licensing.canalrivertrust.org.uk  Once registered with your personal details, navigate to the ‘My Boats’ section and choose ‘Buy an index number’. The charge to buy an index number is £20 and normally takes 3-5 working days for the CRT to issue.
