How to Name (or Rename) Your Boat: The Complete Guide

By Nelson — Director & Owner, Waterline

At Waterline I turn photographs of readers' boats into artwork, which means I read a lot of transoms. And the name on the back of a boat is never random — it's the one thing an owner agonises over, the punchline of a decade of family jokes, or the quiet tribute nobody on the dock quite understands.

This is the complete guide: where the traditions come from, why sailors still swear renaming is bad luck, the full denaming-and-renaming ceremony word for word, how to letter a name so it's actually legal, and 150+ ideas to get you started. Let's get into it.

Why we name boats (and why "she")

Naming a vessel is older than almost any tradition still practised on the water. The Greeks, Egyptians and Romans believed a boat's name established a spiritual connection with the guardians of the sea — Poseidon to the Greeks, Neptune to the Romans — and that the right name was itself a form of protection against everything the ocean could throw at you.

That's also where the champagne comes from. The modern christening — a bottle broken across the bow — descends directly from ancient libations poured to the gods for safe passage. Wine, once; champagne, now.

As for why a boat is "she": nobody can prove it, but the tradition runs deep — the vessel as a protective mother sheltering her crew from an angry sea. (Lloyd's List, the shipping journal, switched to "it" back in 2002, but out on the water "she" is going nowhere.)

Is it really bad luck to rename a boat?

Here's the legend, and it's a good one.

When a boat is christened, sailors believe its name is entered into the Ledger of the Deep — the Book of the Deep — kept personally by Neptune, ruler of the sea. Every named vessel afloat is known to him by name. There's a second court to satisfy too: Aeolus, keeper of the winds, and his four wind gods — Boreas (north), Notus (south), Eurus (east) and Zephyrus (west).

Rename a boat carelessly and you now have two conflicting entries in the Ledger — you're trying to slip something past the gods, and the folklore says you'll be punished for the deception. Robert Louis Stevenson put it in Treasure Island, in Long John Silver's mouth: "What a ship was christened, so let her stay."

Now the honest part: there is zero evidence that renaming a boat brings bad luck. Boats are renamed constantly and every documentation system on earth supports it. But sailors are a wonderfully superstitious bunch, and the ceremony below is a genuinely lovely ritual — so most owners do it anyway, for the story if not the storm gods.

The denaming & renaming ceremony, step by step

The canonical version is the Interdenominational Denaming Ceremony written by marine author John Vigor when he renamed his sloop. Almost every version you'll find online is a variation of his. Here's the full sequence.

The golden rule: you must purge the old name completely first, then rename. Never have both names present at once, and never put the new name anywhere on the boat until the old one is gone.

Step 1 — Purge every trace of the old name (before the ceremony)

The gods must find no trace of the old name aboard. Before you do anything ceremonial:

  • Take the old logbook ashore — don't keep it on the boat.
  • Remove the name from the transom, topsides, dinghy, oars, life rings and fenders.
  • Hunt down every hidden instance: key rings, coffee mugs, glassware, towels, charts, trophies, plaques, books.
  • Remove all paperwork bearing the old name from aboard.
  • Bring nothing carrying the new name aboard yet.

A nice optional touch: write the old name on a metal tag in water-soluble ink, to drop into the sea during the ceremony.

Step 2 — Provision

  • Good champagne, in quantity — Vigor is emphatic that you don't use the cheap stuff, because "one of the things the gods of the sea despise most is meanness." Enough for the sea and the crew.
  • Optional: a silver coin for the mast step, a ship's bell to open.

Step 3 — The denaming invocation

Open with Vigor's lines:

"In the name of all who have sailed aboard this ship in the past, and in the name of all who may sail aboard her in the future, we invoke the ancient gods of the wind and the sea to favour us with their blessing today."

Then ask Neptune to strike the old name from the Ledger (commonly cited wording):

"Oh mighty and great ruler of the seas and oceans, to whom all ships and we who venture upon your vast domain are required to pay homage, implore you in your graciousness to expunge for all time from your records and recollection the name [OLD NAME], which has ceased to be an entity in your kingdom."

Step 4 — Libation for the denaming

Drop the metal tag bearing the old name into the sea from the bow, and pour a good libation of champagne into the water, traditionally from east to west. (Vigor's ceremony has five movements — invocation, gratitude, supplication, re-dedication and libation — and insists the words must actually be spoken to count.)

Step 5 — The renaming invocation

Now enter the new name in the Ledger:

"Oh mighty and great ruler of the seas and oceans, we implore you to take unto your records and recollection this worthy vessel, hereafter and for all time known as [NEW NAME], guarding her with your mighty arm and trident and ensuring her safe and rapid passage throughout her journeys within your realm."

Break or pour champagne over the bow for the new name.

Step 6 — The Four Winds

Face each direction in turn and fling a little champagne to the wind, asking each wind god's favour:

  • North — Boreas: "Great Boreas, exalted ruler of the North Wind, grant us permission to use your mighty powers in the pursuit of our lawful endeavours, ever sparing us the overwhelming scourge of your frigid breath."
  • South — Notus, East — Eurus, West — Zephyrus: repeat the same, naming each wind.

Step 7 — Christen and celebrate

Optionally set a silver coin under the mast, state your intent to care for the vessel, toast her new name, and finish the champagne with your crew. Done properly, it's one of the best afternoons you'll spend on a boat that isn't moving.

How to legally document a boat name

There are two systems in the US, and which one you're in changes whether the name is a legal identifier at all.

State-registered boats (most recreational craft). Your legal identifier is the state registration number on the bow (e.g., "FL 1234 AB"), not the name. A name here is essentially decorative and optional — letter whatever you like. (Rules vary slightly by state; check your state agency.)

USCG-documented vessels (roughly 5 net tons / ~26 ft+). Here the name is federally regulated:

  • A name and hailing port are required.
  • 33-character maximum, using Latin letters or Arabic/Roman numerals only — no symbols or emoji.
  • No name confusingly similar to a distress term (nothing near "Mayday"), and nothing obscene or a slur.
  • **Uniqueness is not required** — the vessel is legally identified by its Official Number, so plenty of boats share a name.
  • Name and hailing port must be lettered on the hull in characters at least 4 inches high, durable and legible; on a recreational vessel they can appear together in one spot (the transom).

(These federal specifics are set by 46 CFR — verify the current text before relying on it, and confirm your state's rules for state-registered boats.)

The most popular boat names

BoatUS has tracked the most-requested names for around 25 years from its boat-graphics orders — the closest thing to real data we have. Recent lists have been topped by names like Andiamo (Italian, "let's go"), Osprey, Serenity, Second Wind, Grace and Shenanigans; past winners include Aquaholic, Squid Pro Quo, Feelin' Nauti and Why Knot?

The themes that win, year after year: relaxation (Serenity, Island Time), a fresh chapter (Second Wind, Next Chapter, At Last), fishing (Reel Time, Reel Therapy), the good life (Pura Vida, Seas the Day) and wordplay (Aquaholic, Squid Pro Quo).

How to choose a name that actually works

A few hard-won rules of thumb:

  • Keep it short. You'll spell your boat's name over a crackly VHF radio to marinas, bridges and — one day, hopefully never — the Coast Guard. Fewer letters is fewer to spell.
  • Radio-test it with the phonetic alphabet. Try saying it: "Whiskey-Hotel-Yankee…". If your clever name is a nightmare over the radio, reconsider — in an emergency, clarity is safety.
  • Avoid anything near a distress call. Nothing close to "Mayday," "Pan-Pan" or "Sécurité" — it's prohibited for documented vessels and dangerous on air.
  • Think about the transom. A great name reads cleanly on the back of the boat at a distance and in glare. Length, font and spacing all matter.
  • A distinctive name saves confusion. There are a lot of "Serenity"s out there.

Once you've got the name, the back of the boat is where it lives — and it's worth doing beautifully. A custom boat name & port graphic of your exact boat, or your name flown on a custom boat flag, turns the name you agonised over into something you actually see every time you walk down the dock.

FAQ

Is it bad luck to rename a boat? By tradition, yes — unless you properly "denamed" it first by striking the old name from Neptune's Ledger of the Deep. There's no real evidence, but most owners do the ceremony anyway.

How do you rename a boat properly? Remove every trace of the old name from the boat, perform a denaming ceremony asking Neptune to expunge the old name, then a renaming invocation and a Four Winds ceremony with champagne. Full word-for-word version above.

Does a boat name have to be unique? No. Even for USCG-documented vessels, the name doesn't have to be unique — the boat is legally identified by its Official Number.

How big do the letters on my boat have to be? For USCG-documented vessels, the name and hailing port must be at least 4 inches high. State-registered boats are identified by their bow numbers, so the name lettering is up to you.

What are the most popular boat names? Recent BoatUS lists have featured Andiamo, Serenity, Osprey, Second Wind, Grace and Shenanigans, with wordplay names like Aquaholic and Squid Pro Quo perennial favourites.
