Pretty much any council beach has wardens in the summer and need to register cheaper to register with Anglesey council in advance and pay the fees locally than register on the beach. Conwy, Gwenydd and Anglesey recognise each other registrations but might have slightly different rules
You might get away not registering if not using a trailer if engine is small but even under 10hp are supposed to register.

This scheme offers considerable advantage to any Anglesey Registered Launchers because Denbighshire, Gwynedd and Conwy Councils will accept Anglesey Registration.
