"Mayflower Sails 2020" was planned
for May, in Boston Harbor.
Postponement is the word they are using now,
not cancellation;
"new dates coming soon," says the website.

(In order to board Mayflower II,
one has to have a ticket,
although the tickets are free;
ticketholders are being asked to hold on to their tickets
while waiting for the rescheduling.)
