Boat christening invitations: berth, boarding time, seasickness

Your uncle calls from the car park. He's at gate C, the boat is at berth 4, and there are eleven minutes between the two. Boat christening invitations get read once, in a hurry, usually standing up. Multiply that car park by thirty guests and you see the problem.

A baptism on the water is a logistics day with a ceremony attached. Nobody remembers the font you picked for the baby's name. Everybody remembers whether they found the boat. So the invitation has three jobs: get people to the exact spot, say honestly what the crossing feels like, and stay correct if the berth changes two days beforehand.

Boat christening invitations: name the harbour, not the city

'The marina' is not an address. Most ports have several entrances, and the one guests drive to by default is usually the wrong one. Write it the way a delivery driver would need it, then add the two times people mix up: when boarding closes and when the boat actually leaves.

• Official name of the marina, plus pier and berth number. 'Port Olimpic, pier 4, berth 12' gets people there; 'the port' gets you seven phone calls.
• Boarding time and departure time, kept apart. If boarding closes at 11:15 and you sail at 12:00, a guest arriving at 11:55 watches you leave.
• The boat's name and one landmark you can see from the car: 'grey hull, opposite the fish market', 'past the blue crane, last pontoon'.
• A map link that opens in the guest's own maps app, and the exact moment you'd change the plan: 'if the forecast turns, we decide at 09:00 and update this same link'.

Seasickness belongs in the invitation, not in an apology on board

If the crossing runs longer than twenty minutes, put the number in writing. 'Forty minutes in open water' lets each guest decide with real information, and it saves you from a queasy friend at the rail who didn't want to make a fuss.

You are not asking about anyone's medical history, you are describing the ride. Suggest that guests who usually feel it take their tablet an hour before, and mention there is a covered area on board where the air is still. Then offer the simple way out: stay ashore and step on later. A grandparent, or anyone with a baby, can wait at the quay and join for the toast once you're back at the pontoon.

The invitation's job isn't to make the boat sound lovely. It's to have the right people on the right pontoon at the right time.

The dress code changes when the floor moves

Ask for grip: flat soles, deck shoes, trainers. A wet deck plus a thin heel is a fall with a schedule. Warn about wind even if the marina is dead calm, because a light layer or a shawl earns its place on the way back, once the sun has dropped. And if the child is wearing white, say it plainly: salt water and a long christening gown don't mix, so pack a change of clothes and leave it in the car.

You can't control the weather, but you can control the confusion. Send the invitation as a link or a QR code, keep the port, the hour and the seasickness note in one place, and when the berth changes, edit it. The same link shows the updated version, nothing gets reprinted, nothing gets re-sent, and the confirmations land in one ordered list so you know who is actually stepping aboard.
