Because Yacht Week holds a separate record about you, and it was affected too.

When you work a Yacht Week trip, you are added to the crew list for that trip. Port and border authorities require identity details for everyone on board, so that list holds your name, email address, passport number and date of birth — inside the Yacht Week system, held by the company running the trip.

The same applies if you were on the Event Team for a booking, or if someone added you to a crew list at short notice.

You have no Yacht Week account and never did. If you try to log in there, you will be told no profile exists for your email address. That is expected, not an error.

Two companies, two separate records, two notices. Keep both — each one lists what applied to that record, and each is your evidence of what was involved.

This is where your login is, and Quarterdeck account passwords were among the data copied. Change yours now, and change it anywhere you have used the same or a similar one — see Do I need to change my Quarterdeck password?

You can also download or delete your Quarterdeck data yourself from your profile page at quarterdeck.co. Use the red Delete my account button — not Go off radar, which only deactivates and erases nothing. See How do I close my account and delete my data?

That one has to be handled in writing, because there is no account to log in to. Write to notice@theyachtweek.com with the name and email address you were listed under, and ask for a copy or for it to be deleted.

Crew lists already submitted to port and border authorities cannot be withdrawn — once sent, they are out of Yacht Week's hands.

Yacht Week's own answers about the incident are at help.theyachtweek.com. Deleting one account does not touch the other.
