In brief
- Treat digital access as part of joining and leaving the yacht.
- Separate guest convenience from operational systems and permissions.
- Practise a response that does not depend on the affected service.
Map the access that comes with a role
A crew member may receive Wi-Fi credentials, a shared provisioning account, a maintenance-system login and access to a group containing guest movements. Each permission can be reasonable on its own. Together they create a digital footprint that may outlast the employment relationship. Start with a role-based access list and a named person responsible for granting and removing each permission.
Include temporary crew, contractors and relief staff. A short stay is not a reason to use an unlimited shared account. Keep administrative privileges separate from everyday use and arrange access through an approved process. The aim is not to prevent people doing their jobs, but to know who can reach what and why.
Put current maritime guidance into practice
IMO's revised maritime cyber guidance addresses governance, third-party risks and the separation of operational and information-technology networks. It frames cyber risk as part of safe management rather than merely an internet-support problem. Implementation and formal obligations depend on the vessel and applicable regime. [1]
For a yacht, a useful starting exercise is to ask what would happen if the guest network, the crew email service or a remote supplier account were compromised. Do not assume those systems are technically isolated because they have different names. Ask the authorised IT provider to verify the architecture and document approved connections. Crew should not reconfigure safety-critical networks themselves.
Close the supplier-access gap
Remote support may be essential, especially away from a major service centre. The access should still have a purpose, an owner and a defined duration. Before work begins, confirm the supplier's identity through an established contact and record the systems they are authorised to reach. Avoid granting broad access in response to an unsolicited urgent message.
At completion, confirm what changed, capture the service record and remove temporary permissions. Include connectivity and audiovisual contractors in the same process as other technical suppliers. Where permanent remote support is genuinely required, have the authorised provider explain the controls, monitoring and revocation method. An arrangement that nobody can describe is difficult to manage.
Teach the moments that cause mistakes
Use short, realistic examples during induction: a changed bank-account request, a link claiming to contain a revised guest list, or a message asking a new crew member to share a verification code. Explain how to verify these requests without relying on the contact details inside the suspicious message.
Make reporting easy and non-punitive. Someone who clicked a link should know whom to call immediately. The first response should protect operations and preserve useful information, not blame the reporter. Give crew an out-of-band contact route for incidents affecting email or messaging. Never ask an untrained person to investigate compromised operational equipment while the yacht is relying on it.
Make departure a controlled event
Add digital offboarding to the departure checklist. Review mailboxes, shared folders, messaging groups, supplier portals, access tokens and any local administrator account issued to the person. Transfer business records to the authorised custodian without treating a departing person's private accounts as company property. Confirm the outcome rather than merely asking whether access was removed.
Finally, run a tabletop exercise with the captain, management and technical provider. Choose one service failure and work through who decides, who communicates and how essential work continues. A useful cyber plan can be understood under pressure. It is not complete merely because a sophisticated document exists somewhere on the network that has just failed.
