Not quite sure how to say this so will try to make sense.  Why do FS attack the offensive power of offensive units.  Fire ships are offensive, period, exclamation point or whatever you need to reinforce that idea.  So, if fire ships are offensive why do they take out offense based on their offensive statistics.  This is even more ignorant that having fire ships as offensive units.  Fire ships were used by the English to defeat the Spanish Armada sent to attack them.  They were never used for offense but they game made them offensive.  That still doesnt excuse offensive units, fire ships not hitting units defensive value.

You "don't think"? Why don't you check? I explained how, it's easy, and it's not my concern if you choose to "think" about something that's easily verifiable.

The Help system shows you some unit's stats, but it disregards their situation, i.e., where they are now (haven, Presidio, island,...). A long time ago, it didn't even put "?" for other people's reinfs, causing a lot of confusion if your own upgrades affect all the reinfs. So, don't rely on it.

P.S. +300% = 4 times more, not 3 times. If you have a unit of 400 basic strength and, say, 75% on research, relics,... and 30k haven def, then their strength will be 400+(300+75)% = 400*4.75.

@Crowbar:

When i get it right, you mean that every 100 Points haven defense grants me an additional Bonus of 1% for my defensive Units ( i think only in my haven and not in General).

that would mean, if i have 30.000 haven defense, it would power up my Units by 300% (expect the other bonuses?)

so. if i have a unit with 400 Point (only as a calculation example) it would have 1200 defense Points + relicts + Research + alchemy potions + Bastion Bonus + Brotherhood Bonus ? that would make something around 1600 Points for that unit. sry but i dont think that there is such an immense Bonus,  nearly no one could defeat you on your Island if this is true.

AND:  the bonuses are shown for my Units. but when i look  on my Units in my haven (not Depot) the 300% Bonus istn shown. not in the additon view and not in the for the total defense value which is also shown.

when you say that this Bonus is active and working, why are These things untransparten?

JSisapirate, we answered all that. The bonus you get is +70% (7000/100=70) on the units' base strength and it protects your troops from raids and blocks, but not Fireships.

No, it was there from day 1, but it wasn't clearly explained. They said "Fireships hit 1 for 1 point" and we assumed that it meant "12600 def points". Only later did we realise that each unit has its points that depend on the unit type (off for off units, average of the 4 def scores for def units,...) and that "1 for 1 point" meant that.

HDB from haven guards has no effect. Only their off/def strength has (which one, though? I never bothered to find out, but I'd guess def).

HDB works but not on FS.  Ye just have to invest enough in it.

One part of HDB that does affect FS.  Scallies, Redcoats, and Gunner's Mates.

I agree that it is absurd to hit an offensive units offensive value with FS's.  I might be wrong but I think it was a change later in the game made to help appease the anti-fireship brigade.
