Virgin Voyages has indefinitely delayed the launch of its fourth ship, Brilliant Lady, citing staffing, supply chain and construction issues.

Brilliant Lady was supposed to set sail in December; but Virgin now has canceled its two festive inaugural sailings, a five-day roundtrip Christmas cruise from Miami and a seven-day New Year’s Eve from Miami, and its regular sailings from San Juan in January, March and April and the April 20 repositioning cruise from the Caribbean to Europe. No firm start date is being announced at this time.

Sailors, as Virgin calls its guests, can switch to similar itineraries on Scarlet Lady or Valiant Lady. Virgin likely also will offer refunds to those who wish to cancel altogether, though it has not yet announced what the policy will be.

The delay follows in the steps of Scarlet Lady and Resilient Lady, both of which also were delayed.
