The Marine Management Organisation (MMO) has confirmed that owners of under-12 metre English fishing vessels fitted with Succorfish SC2 devices will be able to register for a Nemo device from CLS UK. These will be provided and installed at no charge to eligible fishermen.
‘We acknowledge that circumstances over the past few months have been challenging, and we are grateful for the patience shown by impacted fishermen. We will support those who have already secured an I-VMS device to comply with their licence condition by ensuring they have devices that transmit positional data to the UK VMS Hub,’ said MMO Head of Regulatory Assurance Sean Douglas.
‘We have made every effort to streamline the process to reduce the financial and administrative impact on individuals who register by the deadline. I-VMS data is central to our understanding of what is happening in our inshore waters and England’s marine environment, and we are committed to moving forward with I-VMS for the benefit of both fishers and fisheries management.’
Fishermen with SC2 devices are reminded to check their contractual obligations with Succorfish regarding airtime, warranties, access to positional data and purchase of their device. Devices should not be switched off or removed before the replacement Nemo device has been installed.
The MMO states that removal and disposal of a device is the responsibility of the vessel owner and should always be undertaken by a certified engineer and in accordance with local environmental guidelines and MMO guidance, at certified WEEE recycling providers.
The deadline to register for a replacement device is 11.59pm on Sunday 12th July 2026.
Vessels fishing in the Devon & Severn IFCA district are included in this roll-out and should register for a Nemo device to be compliant with the licence condition for English waters. Fishermen are advised to contact the IFCA directly with any queries about Rewire devices.
