Boat Rego Stickers SA | South Australia Registration Numbers

Boat Rego Stickers SA - start with one measurement

If your vessel is under 3 metres, the minimum character height is different from most boats 3 metres and over. Tell us what you are putting the number on, enter the SA registration number and we will make the complete pair from premium 3M marine-grade vinyl, pre-spaced and ready for DIY installation.

You get the legal size you need without turning the side of the boat into a lettering exercise.

TOTAL PRICE $59 – includes both sides, DIY kit & express post

Under 3 metres or 3 metres and over?

That is the key South Australian sizing question for most boats:

  • Vessels less than 3 metres: characters must be at least 100 mm high.
  • Vessels 3 metres or longer: characters must generally be at least 150 mm high.
  • PWC / jet skis: registration characters must be at least 100 mm high.

The number must be displayed on both sides towards the bow, on a vertical surface, in a colour that contrasts with the hull. It must be clearly legible from at least 50 metres while the vessel is underway in clear weather.

If a highly flared bow makes the normal position impractical, South Australia provides a process to seek approval for an alternative position. That is a rules question, so we keep the full detail on the SA information page rather than burying it in the order form.

Big characters expose small mistakes

A 150 mm registration number gives you plenty of room to see when the spacing is wrong. A character tilted slightly or a gap that grows across the line can make a perfectly good boat look untidy.

So we set the spacing before the vinyl reaches you. The complete number is held together on application tape and goes onto the hull as one aligned graphic.

Position the line once. Apply it. Remove the tape. The individual characters stay where we put them.

Every DIY kit includes:

  • FREE application squeegee
  • Clear written instructions
  • Step-by-step installation videos
  • Help from us if you are unsure before you stick it down

Already know what you need?

Skip the homework.

Shipshape Guarantee - confidence before the first squeegee stroke

The difficult part of DIY lettering is usually not understanding the instructions. It is knowing you only get one first attempt.

Our Shipshape Guarantee takes that pressure away. Follow the supplied instructions and, if you make a genuine installation mistake, contact us and we will make a replacement kit FREE.

You still install it carefully. You just do not have to install it nervously.

Ocean Proof™ for SA sun, salt and long weekends afloat

Registration numbers spend their whole life outside. They sit through hot South Australian sun, salt spray, wash-downs and the weeks between trips when the hull is still exposed.

We use premium 3M marine-grade vinyl and our Ocean Proof™ production method because a boat rego number needs to stay stuck, keep a clean edge and remain easy to read long after installation day.

The lettering is cut rather than printed onto a large clear panel, so the hull remains visible between the characters and the result looks more like part of the boat.

The 50 metre test: contrast matters more than clever colour

South Australia requires the registration number to contrast with the hull and remain clearly legible from 50 metres in clear weather while the vessel is underway.

That makes colour choice simple: start with contrast. A dark hull needs a clearly lighter number. A light hull needs a clearly darker one.

Once the contrast is right, choose a clean lettering style that suits the boat. The goal is to make a compulsory number look considered without making it harder to identify.

Boat lettering experience, not just a number generator

Boat Names Australia has specialised in boat names, graphics and registration numbers since 2003, backed by more than 30 years of hands-on vinyl and boat-lettering experience.

More than 70,000 Australian boat owners have used Boat Names Australia, and the site currently displays 341 Google reviews.

That experience matters in small places: how a 150 mm character sits on a curved bow, how close letters can be without crowding, how fine corners behave and how easy the whole line is to position.

We do the fiddly work before the parcel leaves. You get the satisfying part.

How to order SA boat rego stickers

1. Enter your SA registration number

Type the letters and numerals exactly as allocated to the vessel.

2. Choose the vessel and size category

Tell us whether the boat is under 3 metres, 3 metres or longer, or a PWC so the correct minimum height is clear.

3. Pick a strongly contrasting colour

Choose a colour that stays obvious against the hull rather than disappearing into it.

4. We make and pre-space the pair

We cut the vinyl, set the spacing and apply transfer tape so each side is ready to position as one unit.

5. Apply them and get back on the water

Use the supplied squeegee, instructions and video guide to finish the job cleanly.
