Since the Weevil ship is instanced and almost immediately resets if you leave it, if you die, you cannot retrieve your corpse as it disappears. Death marker does remain on the map, it is just gone from the world for retrieval.

Since the Weevil ship is instanced and almost immediately resets if you leave it...
When you die at sea whatever you had should be still on you or in your ship's inventory. If you ship was full then likely you loose it. I tend to not travel with a full ship for that reason. I have died many times at sea and never lost anything however.

You never lose stuff, its just floating on/at the location you died as a post mortem cache you can loot similar to when you sink a ship.
