I think he means the ones that are handed port & starboard, with crossed over arms to prevent the ropes coming out where mooring point is higher than the decks.

it was the /forums/images/graemlins/laugh.gif that made me wonder if he was having a go at another post, maybe someone made a 'daft' statement and he thinks we are all in on the joke???
It might be worth considering if you do really need fairleads at all?
Very often fairleads can be more accurately described as 'unfairleads', ie many have a tendency to chafe the ropes they are supposed to be providing a fair lead for.
A simple chafing strip on the edge of the gunwhale might be just as effective.
Re the para-anchor, would it not be better to lead the rope over a substantial bow roller (perhaps with a locking pin to stop the rope jumping out) rather than through a fairlead (or even pair of them, in a bridle) ?
The bow roller assembly could have splayed out sides at the front of the roller, so that there is not a sharp steel edge to chafe on the line.
Ah! it was a typo /forums/images/graemlins/ooo.gif
I definitely wouldn't think fairleads are suitable.
I would have thought that a parachute anchor would be best deployed from a bridle, wind and sea conditions will dictate how you set the bridle to give the best angle for the boat to lay, so the chances of having the fairleads in the correct position are low.
