That's the question on what the answer is unknown.
The bouns fishing vessel will come with the
preorder option, if you preorder the normal or the donator edition version of the game, you will get the bonus fishing vessel.
Will the fishing vessel be in the later add-on or in "The Shipyard" is still
unknown for us.
But my opinion is YES! I think the fishing vessel will be avaliable to get in the future add-on or even in "The Shipyard".
Because if they have create the ship already, they get the authorizes and they pass al the 48 steps to create it, when the game is released the worth of the vessel will be lost if is just for the preorder option.
So i think the fishing vessel will be able only for the preorder versions until the game is released, when the game is released i think you will be able to purchase the vessel in "The Shipyard".
But that's just my opinion, because those informations are still unknown.
You'l have to be patient and wait until developers gave us some informations.
Search for more informations on the: www.shipsim.com
Or use the search on the forum.
Kind regards.
