Naval Fighting Instructions is Nationa Idea that give us 50% blockade efficiency. There is lots of uncertainty of usefulness of this NI. In this thread I will try to share my knowledge about that NI, and about blockading in general as needed for explaining NI benefits.
Rule of thumb:
Blockading earn you cash based on trage good value, NFI increase that amount by 50%, and that cash go directly to your treasury! However good Privateer advisor can give you up to 3 times gold NFI would. So geting advisor should be your priority. NFI however is good for short wars against profitable targets (with lots of spice, tobacco, coffee, etc.), or when you do not have naval tradition. Or when you need cash for going over naval/land force limit. And for prolonged wars against land powers (ie England blockading France) NFI + privateer is a must have. If enemy have less then 300g in trade value in provinces you will block, NFI is not worth it.
Requirements:
1 slot for this NI
30th naval tech level
Benefits:
50% for blockade efficiency
Secondary benefits:
Events Improved Blockade Tactics / Slipping Standards
Enable national decision Enlist Privateers
Analysis of primary benefit:
After reaching 9th naval tech level, each country have blockade efficiency set for base value equal to 100%. It can be improved by 50% from NFI, but it also can be improved by 120% 6* advisor, and another 25% from 5/6* advisor bonus. While advisor slot may be more valuable comodity than NI slot, however its easier to swap, and give up to triple benefits. So one could choose NFI only if maximizing blockade efficiency was real priority.
Analysis of secondary benefits:
If you want EP, you probably already activated it by selecting See Hawks, or Superior Seamanships NDs, as those are always available.
And IBT give only 5% for blockade efficiency. Hardly worth the effort. SS on the other hand give rather big -25% for blockade efficiency, that you can feel.
So secondary effects of this NI do not add any significant value to it. Judgment upon NFI boils down to just its primary bonus.
Test results:
As shamanist Venice I can earn 60g per month in 1650 in situation where I blockade each port in Mediterranean (and Black) see. Only NFI add to blockade efficiency. So this NI add 20g to my coffin. It would also allow for paying for 160 threedeckers + 160 heavy frigates if naval force limit was 320, and fielding 30k army, just from prize cash!

0.91 Added results from test game.

Blockade 101 for complete novice:
Constant blockade effects:
-75% for tax income in blockaded province
-75% for trade good value in province (which is basis for production value, which go down for that reason too)
Up to 25% War Score for blockading ports (depend on ratio (number of ports / number of provinces ))
Blockade effects depending on modifiers:
6% of trade good value (after taking into account blockade effects) (15g translate into 1g of your income with 100% BE)
Maximal WE possible from blockade (unconfirmed)
Monthly WE increase from blockading ports (unconfirmed)
Secondary benefits:
WE usually is high that RR% is enough to lower tax income in each enemy province.
If enemy have large coastline WE rise high enough to cause all its nasty effects.
General tips:
Blockading is viable as fast mean of rising War Score especially on heavy-coastal countries, however its full destructive potential show in rising enemy WE.
This also mean that comparatively land locked countries can shrug off effects of blockading more easily. There blockading still is important tactic but will not win war.
If full blockade is not possible, and picking targets for blockade is necessary two factors are important. Military importance (blocking straits, blocking major naval fleets), and Trade|Production value of province (higher the more enemy loose, and more income you gain).
If you want to select Privateer for his blockade efficiency increase you may replace Master of Mint, as both of them add cash to your coffin directly, and on prolonged wars bigger advantage in tech can flip victory to your side.
