If your sea time has been on vessels less than 200 GRT, the CG-719S form is the preferred method of tracking sea days.

Do I need a new CG-719S for each vessel?

Yes. You will need a separate form for each vessel you worked on. They can all be for the same company.

What needs to be on a company Sea Service Letter?

The letter must be on letterhead from either the company that employed you or the vessel on which you served.

Include the date the letter was written.

Also include:

  • vessel name
  • official number
  • vessel type
  • propulsion type
  • tonnage
  • engine horsepower (when applicable)
  • the beginning date of service
  • the end date of service
  • number of underway days
  • position held when aboard

For any officer endorsement, the letter must also supply a breakdown of the number of days of service within 3 years of the date of the letter. For any Tankerman endorsement or renewal of any endorsement, the letter must supply a breakdown of the number of days of service within 5 years preceding the date of the letter.

The letter must indicate whether the service was 12- or 8-hour days. If the service is 12-hour days, it must attest that a two-watch system has been authorized by the vessel’s Coast Guard Certificate of Inspection (COI), and the COI must actually authorize that.

Where do I get a sample sea service letter?

Sample letters can be found at this USCG site.
