Ohio boat lettering guide

Ohio Boat Registration Number Requirements

A clear guide to Ohio boat registration number size, placement, spacing, color contrast, and validation decal positioning.

Where Ohio Boat Numbers Go

Display the OH number on each side of the forward half where it is clearly legible. The number should remain visible, legible, and free from other markings that could make it hard to identify.

Core Display Requirements

  • Use the state prefix OH exactly as assigned on your registration.
  • Use plain block characters at least three inches high.
  • Read the complete number from left to right.
  • Use a strongly contrasting color against the hull or background panel.
  • Separate letter and number groups with hyphens or spaces equal to a character width.

Validation Decal Placement

For numbered watercraft, Ohio law directs each tag six inches toward the stern from the identification number. Install decals only after cleaning and drying the surface, and keep them visible for inspection.
