Buying Guide
What should you consider when choosing boat decals?
- Compliance: Ensure decals meet US Coast Guard guidelines and hull labeling requirements for your vessel type.
- Color and visibility: Choose colors that maximize readability against your hull color and under glare conditions on the water.
- Durability: Look for UV-coated vinyl and fuel-resistant formulations to withstand sun exposure and gasoline contact.
- Size and quantity: Confirm the decal height (commonly 3 inches) and the total piece count to fit your hull dimensions and lettering needs.
- Application: Favor peel-and-stick kits with clear instruction, especially for large registrations on curved surfaces.
- Finish: Solid colors vs. gradients offer different aesthetics and readability; gradients can hide minor misalignments but may require careful placement.
- Maintenance: Consider how easy it is to clean and how decal materials respond to saltwater and cleaning agents.
