Presumably the boatyard charged you more for adding the bungs? As for electrolytic problems, bronze seacocks shouldn't be electrically connected to anything.
I think on your own boat it's somewhat different, and boils down to your knowledge of the boat and your assessment of risk. I think it's highly unlikely that one of my seacocks will suddenly fall off, so I don't have bungs on board. .
I thought that until I pulled the log spinner to clean it and the hull fitting snapped off at the hull.
Why did it snap off? Corrosion? Undue force?

certailnly not undue force on my part, but the NASA target log was already fitted to the boat I bought.
But what size bung should be attached/near the seacock?
Fits the hose tail?
Fits a broken seacock?
Fits the hole the seacock should be filling?
That's three different sizes
Never had a straight answer, even from those who specify the requirement!
I would like to buy some soft wood bungs to be tied by the various sea cooks (I have 5 sea cocks aboard). All I've seen are sets with various sizes in. Does anyone know if there is somewhere I can buy just the ones I need (in the UK or Ireland)?
You could try a brewing supplier?? This is an American site but I assume UK suppliers would sell as well? http://www.eckraus.com/search?q=bung
I also just keep mine in a box next to then flares, emergency VHF antenna etc. You'll never know the size of the hole until it happens...to me tying them on seems about as sensible as tying your fire blanket to your cooker...

Oh and if you have seacocks under floorboards, in cupboards or behind seat cushions.. Who has bright labels clearly visible showing which things to lift/open/move and then in which direction to look..?
Who has a plan, clearly displayed (or available) on board showing the locations of all thru-hulls, whether above or below the waterline.. It's another useful card and only takes a short while to make..

You can see now what has been on my task list this last winter...
