U.S. law treats a vessel’s hull and deck design differently from a drawing, 3D model, surface decoration, or logo depicting it. Fair use may apply to some uses of copyrighted material, but it depends on the specific source and use.
This guide focuses on U.S. federal law. Other countries may apply different rules, and a particular project may also involve rights such as trademark that are outside the copyright and vessel-design analysis here.

First identify what you mean by “ship design”
A game asset can combine several different things, and they do not all receive the same legal treatment. Before assessing permission or fair use, separate the underlying vessel design from the artwork used to depict it and from any branding or decoration.

U.S. copyright guidance treats the hull and deck design of a watercraft as a useful-article design, not as copyrightable subject matter in itself. A separate federal regime may protect qualifying vessel designs.
- Drawings, plans, illustrations, photographs, and 3D models: these are expressive works that depict a ship. The fact that the ship’s hull design is not copyrightable as such does not make a drawing or model free to copy.
- Ornament and surface art: decorative artwork on or in a hull or deck may have copyright protection separate from the vessel’s overall form.
- Name, logo, or insignia: these can raise trademark or other issues that are not resolved by copyright or fair use alone.
This distinction is central to the U.S. Copyright Office’s Compendium chapter on useful articles (2021 guidance) and its explanation that drawings, models, and statuaries of vessels are not granted or denied copyright protection simply because they depict a vessel.

What Chapter 13 protects—and what it does not establish
Title 17, Chapter 13 establishes a vessel-design protection regime separate from ordinary copyright. It addresses an original design of a useful article that makes the article attractive or distinctive to the purchasing or using public, subject to the chapter’s requirements. The statute expressly addresses vessel hulls, decks, and combinations of the two, including plugs and molds.
The statutory definition of a vessel is narrower than “anything that looks like a ship.” Under 17 U.S.C. § 1301(b)(3), a “vessel” is a craft “that is designed and capable of independently steering a course on or through water through its own means of propulsion” and “that is designed and capable of carrying and transporting one or more passengers.” The statute also defines hull and deck with exclusions, including specified superstructure and attachments.
For a video game, that means you should not assume that every fictional ship, spacecraft, or digital design qualifies for Chapter 13 protection—or that none can. The statute’s definitions concern qualifying vessels and designs; they do not, on their own, settle how every purely virtual depiction should be treated. The U.S. Copyright Office’s Title 17 text reflects amendments through December 18, 2025.
The Copyright Office’s Compendium says the overall shape and form of a watercraft’s hull or deck is a useful-article design and cannot be protected by copyright law as such. It separately notes that purely ornamental two- or three-dimensional decoration on or in a hull or deck might be copyrightable. Chapter 13 does not itself provide, extend, or limit copyright protection for a drawing, model, or sculpture of a vessel.
Rank #3
When a game ship may involve ordinary copyright
The right being assessed depends on the source material and on what the game actually uses. A developer might work from public historical facts, a physical vessel, a protected plan or photograph, an existing game’s model, or a mixture of sources. A functional feature or historical fact is not the same thing as another creator’s expressive drawing, model, or ornamental art.
For example, rebuilding a ship from independent reference material is a different question from importing another game’s 3D model or tracing a distinctive illustration. The hull’s useful function does not automatically clear expressive artwork used to represent it. Conversely, the mere fact that two ships share commonplace or functional features does not establish that one copied protected expression. The analysis depends on the particular material and circumstances.
Rank #4
How the four fair-use factors apply to a game
U.S. fair use is a case-specific balancing of four statutory factors. The Copyright Office’s fair-use overview describes them as a combined inquiry; no single factor automatically decides the result.
| Factor | Questions to ask about the game |
|---|---|
| 1. Purpose and character | What is the game doing with the material? Is it using a source to criticize or comment on it, or mainly reproducing the source’s appeal? Is the use commercial, nonprofit, or educational? A commercial release matters, but does not by itself rule out fair use. A noncommercial or educational purpose does not automatically establish it. |
| 2. Nature of the copyrighted work | What kind of work was copied—for example, a technical plan, a photograph, an illustration, or a detailed game model? This factor is considered alongside the others; the work’s label alone does not settle the outcome. |
| 3. Amount and substantiality | How much was taken, and how important was the material taken in relation to the work as a whole? There is no automatic safe amount based on a small percentage, brief appearance, or limited number of assets. |
| 4. Effect on the potential market | Could the game substitute for the original or affect a relevant market for the work, such as licensing the asset? Consider the particular work and use rather than assuming that any commercial use causes market harm—or that a new audience means there is none. |
The Copyright Office says that uses adding something new with a further purpose or different character, without substituting for the original use, are more likely to be considered fair. That is guidance relevant to the purpose-and-character inquiry, not a separate rule that guarantees fair use. Its Fair Use Index overview, last updated in July 2026, also explains that the index is not comprehensive or legal advice.

A practical way to assess a ship asset before release
- Record the source. Identify whether the design came from an actual vessel, historical plan, licensed asset, public-domain material, or another game. Keep the references and any licenses or permissions with the project records.
- List what was used. Distinguish functional or commonplace features and overall hull or deck form from copied drawings, photographs, model geometry, surface decoration, names, logos, or insignia.
- Check the relevant rights separately. Ask whether a source work may be protected by copyright, whether a vessel design could meet Chapter 13’s definitions, and whether branding or other rights need a separate review. Do not treat an answer to one question as an answer to all of them.
- Apply all four fair-use factors to the actual use. Document the game’s purpose, the nature of the source, the amount and importance taken, and the plausible effect on relevant markets. Explain why the use is or is not transformative without treating that label as conclusive.
- Resolve uncertainty before a high-stakes release. If the project closely reproduces a source, ownership or license terms are unclear, or the game will be commercially released, get advice from a qualified attorney familiar with the relevant rights and jurisdiction.
What this analysis cannot decide for a particular game
These principles do not establish that a particular historical, military, fictional, or virtual ship is free to use. They also do not determine who owns an asset, whether a license permits the intended use, whether a source is in the public domain, or whether foreign law, trademark, or trade dress applies. Those questions require checking the specific source, asset, territory, and project.
