Will my garmin accurately measure my mileage if I run on deck of a ship while it is moving?

no.
You could probably figure things out if you had access to the data and preferably took lap times.
0/10 but on the off chance you are retared and really asking this, no it will not be at all right.
Your best bet is to find a wheel of some sort, a well inflated tire will work the taller the better. Mark the edge of the wheel in one spot. Then roll it around the deck and count the number of rotations based on the mark, make sure it is not slipping. Travel the running path for one lap. When you finish and know the exact number of rotation it took measure the diameter of the wheel (distance across it at its widest point in feet). Make sure to convert inchs and fractions of inchs to tenths ex 8.5in= 8.5/12=0.708333 ft. Then multiply this by 3.14159. Multiply this number by the number of rotations you got from rolling it around. This will give you the number of feet in the path. Not sure how long your path is but one mile will be 5280 feet so if your path is say 660 ft it will be 8 laps to a mile to give you an example.

Is this a joke? How about you just do Badger Miles?
If you are running a fixed route around the deck, why not just measure one lap with your Garmin when the ship is docked in port? Then all you have to do is count your laps and multiply?
I think you could do this. See if this seems logical. Assume you are running forward and back only in the axis of the ship's travel:
The Garmin will display your speed relative to the satellite: it will think you are running forward all the time at speed of (Y+X) (forward) and (Y-X) (backward). (Y=ship's speed, X=your speed relative to the ship). Your average pace will be Y, the ship's speed.
However, if you stand still, you can read Y on your Garmin. Then subtract Y from your lap pace (Y+X, or Y-X) to get X, or -X. Multiply your speed by the time spent running to get distance.
You could also collect GPS data from two Garmins, one sitting still on deck, the other on you. You can calculate your position relative to the stationary Garmin for each second and plot your movement through space in the reference frame of the ship.
You could also run a lap while the ship is tied up at dock to get distance, and keep track of laps run while at sea.

Or do this, I was just assuming that he was on a long naval trip that the boat wasn't going to be stationary on.

Badgers! We don't need no stinking Badgers!

I've tried running on a cruise ship before that had a "jogging track" according to the website. It can't be done. Its too small and the deck will be lined with people. You'll spend all your time just trying not to run into anyone. The ship I was on had a small workout room with a few treadmills so I did all my runs on those.
No. Not only won't it work on a moving ship, it also won't work (well) on a stationary ship, unless it is a very huge ship and your track is around the edges.
In my experience, the Garmin does quite well when I run long straight distances and gets confused by tight turns, including the turns on a 400m track. So a run that is all tight turns will give you very inaccurate readings.
It will be more accurate than you think. Whether the ship is moving is immaterial. The Garmin will record too much distance when you're running in the direction that the ship is moving and too little distance when you're running in the opposite direction.
As already mentioned, the real problem is that the Garmin doesn't handle routes with a lot of turns very well.

Um, no. It will be off by exactly the velocity of the ship.
Simple thought experiment: He stands still on the deck and hits "start", waits a bit, and hits "stop". the garmin records that he's moved the same distance the ship traveled. Nice way to inflate the mileage count for the week, though...
The nice thing about being on the ship though, is that the garmin should work fine on the treadmill... since you're on the ship that is actually moving.

It depends on the ship. I ran on one of the Disney cruise ships and the deck you were supposed to run on was fine, at least for a few days - no worse than doing laps on one of those indoor tracks at a gym. Just get up early and you'll have it mostly to yourself. Still better than a treadmill.
Like he said^^. It also depends on the time of day. I ran fairly early in the morning and it was all clear. You also get to see the sunrise over the ocean.

I guess I was just on an old ship. Still, I would rather be on a treadmill than on a flat track that's 200m or less. I hate those sharp curves.

OK, then. What if I run on the dreadmill while the ship is moving? Will the garmin measure the ship's velocity only?
Sorry, I have a hard time understanding complicated physics questions. Thanks for your help.

Yes it will measure only the ships velocity and won't do you any good.
I assume that you are going on a cruise ship and not a navy ship. In that case, embrace the spirit of the cruise, just relax and run. Leave the Garmin on shore.
(If you are on a naval ship - stay out of trouble, get home safe and thanks for your service.)
