Is it legal in the state of Washington to operate without a vessel safety check decal?

In Washington state, it is not legally required to have a vessel safety check decal to operate a boat. However, having a safety check and displaying the decal can indicate that the vessel meets certain safety standards, which may be beneficial for compliance during inspections or if stopped by law enforcement. It's always a good idea to ensure your vessel is safe and compliant with all regulations, regardless of the decal.
