How to boost sea trade ONLY?

[popovic]

The title sums it up pretty well.

Now, I know that there is the "trade_level_bonus" building effect that affects only land trade.
Is there perhaps a similar one, but only for sea trade?

Yes ports, merchant wharfs, the red text is the bonuses!

        }

The export_descr_buildings.txt controls most of the bonuses for buildings.

The trade_base_income_bonus boosts both sea, and land trade.

As shown there it's 'trade_fleet x'. I think that's the only relevant bonus, it's the only one that boost sea trade exclusively.

Thanks. Now, I read somewhere here on the forums that the max number of trade fleets you can give to a building is 3.
Is that true, or you can give more?

Just to answer to my own question (partially): 3 sea trade routs is not the limit. I managed to get 4 for Venice, and I guess more is doable.

However, I believe the issue is that certain settlements can`t establish sea routes between each other.
Now, can anyone confirm that?
