Shipbuilding part 4, Improvement (updated)

Lets start the art of shipbuilding.
It's the same as freestyle shipbuilding.

But this time you choose the ship you want to improve. Don't equip your ship.

Unlike freestyle shipbuilding, you don't need Hull part. I would suggest prepared at least 2 armament part and 1 sail part, unless your ship already has max sail improvement.

You also need special shipbuilding permit (SSIP) before you can start improving your ship. As you can see on the bottom left menu, this improvement need 2 SSIP, and I have 59 SSIP in my bag.
How much SSIP you need for each improvement will be vary as shown in this menu.

The required rank for each improvement also increase. Fleet with R19 or R20 shipbuilder are highly recommended if you're looking for great success result on your improvement.

Now we will take a closer look on improvement stat. I presume you have read part 3 of shipbuilding in this blog.

As you can see, improvement has limit. Even if you have improvement value 150, while your upper limit is 50, you will have 50 only, and waste 100 improvement.
Understand your ship limit will help you decide to improve your ship wisely and in the end also help the resell value of your ship.
However, its not working with negatives stat as bellow.

Even you have limit 17, don't forget it is Upper Limit. There's no lower limit for improvement. As you can see in this picture, it has -32 on hold capacity. Since we have aide ship, this won't be a big deal isn't it.

When a ship has reach max improve. Some ship can have additional improvement slot. As you can see with this ship bellow.

You can go to colony and get extra ship improvement.

And you will see this menu.

Ship which has red colored "Extra Improvements" mean they can't have more extra improvement.
Each extra improvement will need 1 SSIP.

Doing this will increase your ship level requirement. In this ship, it increase it maritime level from 17 into 22. Increasing level also mean increasing "required shipbuilder rank" for next improvement.

Here you can see the 1 of the ship has been increased the improvement slot.


Suggested when you have a ship with 0/5 improvement, improve your ship into 5/5 first before adding extra improvement slot to 5/6. If your ship able to have 2 extra improvement, then you should make it to 6/6 first, before adding the last extra improvement into 6/7, and finally 7/7.

I guess this should be enough for improvement part.
