Like it was said above: The form must be signed by the "owner, operator, or master"
For US flag vessels you can easily find the owner by searching the NVDC website by Official Number or boat name. Do a "Print Preview" and print a .pdf of the entry and attached to your Sea Service for. CG - 719S. If you have the vessel documentation
attach that too. That's what I do with my own boat and I sign as Master since the doc is in my wife's name. With your own boat it's an honor system but, as mentioned, right up to the point where the want to hang you for something.
For other boats, including foreign, I would write down the hull
number and boat name and if I weren't the skipper
I'd get his/her name and email
and send him/her a completed form and ask to have it signed and return. For charters I include a copy of my charter company's invoice which shows me as the "charterer" and therefore the master.
Here's some stuff on the subject that I previously posted on this forum, I think it's still current
Use Sea Service Form (CG - 719S). A “sea day” is defined as 4 hours continuously underway. Don’t go for two hours, anchor
for lunch, and then go for another two hours, none of it will count. A “sea day” is also defined as within the same calendar day. If you depart at 22:00 hrs. Monday and complete your voyage at 03:00 hrs. Tuesday it generally will not count either. There is an excepting for commercial
voyages over six hours spanning two calendar days which allows one or one and a half sea day to be logged.
Sea service on any vessel, commercial
, recreational, military, police, etc., will count as long as it meets the above requirements. If you were a crew member
on a military vessel they will provide you with proof, or at least the Navy
& Coast Guard will.
Row boats, kayaks and canoes (human powered) generally don’t count even though they may be considered “powered vessels” for Rules of the Road purposes. Strap an outboard motor
(or sail) on to your canoe and motor
around for four hours each day for 360 days (OUPV) or 720 days (Master) and you’ve got it. Don’t laugh, I’ve heard it’s been done.
I think any Master application original or up-grade still requires a vessel of 5-GRT minimum and that will get you a 25 ton license
Note: Any master's ticket is good up to 100-GRT for OUPV only but mindful of the OUPV limits (6-pack, no cargo, no foreign ops, etc.).
The Sea Service forms must be signed by the vessel owner, master or other authorized person connected with the vessel or its owner. Years ago they had to be notarized but no more, it’s the honor system.
I go to the USCG Vessel Documentation
Center website and look up the vessel by name or Official Number (for US documented vessels only). That record
will show who owns the vessel, their address and data about it, including Gross Registered Tonnage, for you license grade or up-grade. I select “print preview” on the web page with the information on screen
, print it out and affix it to each copy of the Sea Service form I’m going to submit to the USCG for renewal or up-grade.
Sea days on any vessel, foreign or USCG documented, state registered, military, etc. or not registered at all, are usable if supported by complete information.
