NSW Boat Registration Numbers — Display Sizes and Placement

How to Register a Boat in NSW

The first step is Service NSW (for Transport for NSW): register the vessel or check an existing registration there. This page does not replace that process. Once you have a NSW number, you still need to display it on the hull at the published heights.

To register a boat in NSW, you typically need to:

• Confirm your vessel needs registration — most powered recreational boats and PWCs used on NSW waters must be registered.
• Apply through Service NSW — submit vessel details, proof of ownership and pay the applicable registration fee.
• Receive your registration number and label — Service NSW assigns your number and issues the registration label.
• Display compliant hull numbers — apply registration numbers to both sides of the hull in the size, colour and placement set out below.

What NSW Requires

Boating in New South Wales involves more than simply registering your vessel. To be legally compliant, your boat must display its registration number in a way that meets state regulations and guarantees visibility. These standards ensure that in an emergency, inspection or enforcement situation, the registration number can be easily read by authorities or rescue services from a distance.

How Big Do the Characters Need to Be?

• Standard boats: Mechanically propelled boats registered in NSW must display registration numbers with characters at least 150mm high.
• Jet skis and sailing craft: Personal watercraft (jet skis) and sailing craft may use smaller characters, with a minimum height of 100mm.

Where to Place the Numbers

• Both sides of the vessel: Your registration number must be shown on each side of the hull (or on the transom if it is a sailing vessel).
• Above the waterline: Place the numbers well above the normal waterline so they stay clearly visible even when the boat is underway.
• Nothing in the way: Numbers must not be blocked by equipment or graphics. Avoid spots where spray, hull fittings or gear could hide them.
• Visible when underway: Position the numbers so they can be seen from both the left and right sides while the vessel is moving.

Colour, Font and Layout

• Contrasting colour: Numbers must contrast with the hull so they are legible from a distance — white or light colours on dark hulls, dark colours (like black) on light hulls.
• Solid, clear text: Use uppercase letters and numerals in plain block characters, proportionate in width to height.
• One straight line: Align the characters in a single straight horizontal line — not curved or stacked.

What to Check Before You Buy

When purchasing NSW boat registration decals, confirm they meet these criteria:

• Character height of at least 150mm (or 100mm for jet skis) to meet minimum size requirements.
• A contrasting colour option against your hull for maximum visibility and readability.
• Suitable for both sides of the vessel and application above the waterline.
• One-line layout that aligns with standard readability practices.
• High-quality outdoor-rated vinyl so the numbers stay legible and adhered through sun, saltwater and constant wear.
