Many boats must display registration numbers, documentation details, or other identification. When a boat is wrapped, these markings need to be planned into the design. Getting them wrong can create problems with authorities, while getting them right is simple with some planning.
Know the rules first#
Requirements vary depending on where the boat is registered, how it is used, and whether it is documented. Rules may cover:
- What must be displayed
- Minimum letter or number size
- Placement on the hull
- Contrast with the background
- Character spacing and style
We can't give legal advice on your boat's specific requirements, so check with the relevant registration authority before finalizing the design.
Plan markings into the design#
Registration numbers are easier to integrate when planned from the start. A busy printed design can make numbers hard to read. Consider:
- Leaving a plain area of contrasting color for numbers
- Using bold, simple characters
- Keeping numbers away from fittings and curves
- Making sure they are visible from both sides
Contrast and legibility#
Required markings usually need to stand out clearly. On a dark hull, use light characters; on a light hull, use dark characters. Avoid placing numbers over patterns or photographs.
Applying numbers over a wrap#
Numbers can be cut from vinyl and applied on top of a wrap, or printed into the design. Applying them separately makes it easier to replace them if registration changes. If they're printed into the wrap, changing them later may mean replacing a panel.
Changing registration#
If you sell a boat or change its registration, the numbers may need to change too. Keep a record of the font and size so replacement graphics match.
Durability of required markings#
Required markings need to stay legible for as long as they are required, which may be longer than a decorative wrap's life. Cut vinyl numbers in a solid color often hold up well and are simple to replace. Check them as part of your regular inspections, and replace any that fade, peel, or become hard to read. Faded numbers can attract attention you don't want during an inspection on the water.
Documentation and hull ID#
The hull identification number is usually molded or fixed into the hull, often on the transom. A wrap should not cover or obscure it. Ask your installer to keep it visible.
Commercial vessels#
Commercial vessels may have additional marking requirements. Our commercial fishing regulatory markings guide covers these in more depth.
