Suggestion of quality of life updates & new naval unit.

*New naval unit*

Before we start with this, I would like to talk about a change that should be made, which is that players can send any land unit only by boarding at a port, which is not too gamebreaking, since a port is already valid from day 2

this unit will be a speedboat type, it can be built in a level 2 workshop on the sea coast and should help any land unit to move 50% faster on the sea and have a capacity of 10 light units

if we want to transport tank-type units or heavy units in general, we have to use a convoy, which is already the method we currently use to transport, so therefore it will be transported slower than the units that can use speedboats

If we are still at this point, I would also like to introduce the blockade of the port, which is an operation that light cruiser and battleship, can do this operation with the effect of:

Disable the targeted port (so no ground unit can cross the sea until it gets rid of the ships blocking the port laso the bonuses from the port are disabled so no 25% more production from it) the only ways would be other ships planes but also ranged units such as artillery and railgun.

Here I would still like a huge buff to the railgun so that this new concept to fit better, by that I mean to give it 40 dmg vs land and naval units since it is already quite expensive to maintain one needing railways to move, I would prefer the artillery to be the basis for the light cruisers that block the port and the railgun to be an essential weapon in the fight with battleships, I know that the bomber is also a good weapon but it is already used for several things and it would be the time for the railgun to be the best weapon at something, not just the shadow of the artillery and the bomber.

And a short note that I think it's better for ships to use 20 fish instead of 20 grain for maintenance.
