This is freaking amazing! I finished creating this stupid Paradox account just so I could post that

Great job bro!
A few things to help others:
You have to build your Harbor first. You do not need to create and lines or connections at all, but it must be built first.
> Then build Boat Depot
> Then Piers
The side you BEGIN your Line on matters. From the orientation of on land - looking toward water:
RIGHT SIDE WILL SPAWN SMALL BOATS

LEFT SIDE WILL SPAWN CRUISE SHIPS

Only where you begin. You can start on (R) to spawn small boat, then connect back and forth afterward. Will still spawn small boat.
ALL IN ALL A PHENOMENAL ADD TO THE GAME AND A GAME CHANGING MECHANIC!
