### Valid Accept Headers

- `application/json`

### Description

This operation retrieves highly detailed information pertaining to vessels. It should be used if you need to reduce the "chattiness" of your application and don't mind receiving a larger payload of data. The results include and expand on what's already available through the following operations:

- `/vesselbasics`
- `/vesselbasics/{VesselID}`
- `/vesselaccommodations`
- `/vesselaccommodations/{VesselID}`
- `/vesselstats`
- `/vesselstats/{VesselID}`

A VesselID, or unique vessel identifier, may be optionally passed to retrieve a specific vessel. A valid API Access Code from the WSDOT Traveler API must be passed as part of the URL string.

Please consider using `/cacheflushdate` to coordinate the caching of this data in your application.
