Will yacht Wi-Fi or Starlink be reliable enough for work?
Ask about the service plan and onboard network, not just the presence of an antenna. Starlink’s maritime information distinguishes ocean service and priority-data arrangements, including changes in service after a data allowance is exhausted. (starlink.com)

Give the yacht a realistic workload: simultaneous video calls, VPN access, large uploads, streaming and the number of devices.
Then request:
- Current service provider and plan.
- Coverage relevant to the proposed route.
- Included data and additional-data authorization.
- Recent performance observations, with location and date.
- Guest-network coverage in the cabin or office you will use.
- Backup connectivity and the person responsible for it.
- The plan for a genuinely time-critical meeting.
Our recommendation: do not make an irreplaceable business obligation depend on an untested promise of “high-speed Wi-Fi.” Schedule a trial with the yacht’s team where feasible and agree a practical fallback, such as a suitable shore location.
Do not mistake a successful speed test on one day for a service guarantee for the whole charter.
