Golden Shellback Ceremony: Cross the IDL at 180° Longitude

Mark the moment you become a 'Golden Shellback' — the rarest of nautical honours — by standing precisely at the intersection of the International Date Line and the Equator at 0°, 180°. This is a once-in-a-lifetime celestial milestone celebrated with full ceremony aboard your vessel.

What to expect

Your ship's officers preside over a solemn yet joyous Neptune's Court ceremony on deck, dressed in full regalia. You are officially proclaimed a Golden Shellback — a distinction held by only a fraction of all ocean travellers. A beautifully printed, personalised certificate is presented, and the moment is photographed for posterity. Champagne is poured as the ship holds its course precisely on the 180th meridian.

Good to know

The crossing occurs at sea — no tender or all-aboard timing to worry about. Check your daily programme the evening before for the exact time of crossing. Pre-register your interest with the voyage desk to ensure your name appears on the certificate. Dress for a deck event; tropical-weight layers recommended.
