If you operate a fishing-charter or livery vessel in Wyoming, your boat carries three layers of markings: USCG documentation or state registration numbers, a state validation decal from the Wyoming Game and Fish Department, and any commercial / livery identifiers. This guide explains the rules, sizing, placement, and what vinyl survives high-altitude UV and harsh winters.
Registration Numbers
Vessels registered in Wyoming display a number in the format XX 1234 YY on each side of the bow. Standard rules:
- Character height: 3 inches minimum
- Style: block letters / numerals, no script
- Contrast: color that contrasts the hull background
- Separation: hyphen or space between prefix, number, suffix
- Reading: left to right on each bow
USCG-documented vessels skip the state number but must display the documented vessel number inside the hull and the official name + hailing port externally.
Wyoming Validation Decal
The Wyoming Game and Fish Department issues a validation decal at registration / renewal. It mounts on each side of the bow, within 6 inches of the registration number, in line with the number. Replace at every renewal.
Charter & For-Hire Markings
USCG-licensed charter captains operating six-pack (under-six-passenger) or inspected vessels follow USCG marking rules first, then state. Most Wyoming charter operators display:
| Marking | Required? | Placement |
|---|---|---|
| State registration # or USCG doc # | Yes | Bow each side / hull interior |
| State validation decal | Yes | Within 6″ of bow number |
| Vessel name + hailing port (USCG) | If documented | Stern |
| Charter business name / phone | Optional / brand | Stern, transom, hull side |
Livery / Rental Requirements
Livery vessels (rentals) typically need additional identifiers; owner / operator name, a livery designation, and emergency contact info. Confirm specific Wyoming sizing with the Wyoming Game and Fish Department before printing.
Marine-Grade Vinyl
Salt water, UV, and high-altitude UV and harsh winters are brutal on standard sticker vinyl. Spec to look for:
- 6-mil cast marine vinyl with UV-stable inks
- Pre-spaced application tape for clean alignment
- Apply above waterline, on clean / wax-free gel coat
