Hey, I didn't say that there's anything special in using a kedge, did I?
I was just reporting my experience: believe it or not, I enjoyed many peaceful nights anchored in the Med, occasionally with strong winds, and never used it.
Whenever swell and wind took different directions (which is rare anyway), it has never been so bad to become really unconfortable.
I guess it might also be a matter of choosing the right spot - whenever a bay is badly exposed to waves/swell, I just look for something better.
Then again, when I wanted to spend a few days in the same place, I just deployed both bow anchors, properly distantiated, attaching a couple of crossed lines stern to shore. As secure as in most marinas. But also in this case, why on earth a stern anchor would be necessary? If any swell is entering the bay, surely it's from the open sea and not from the shore, innit? Therefore, isn't it better to offer the bow rather than the stern to it?
Anyway, each to their own of course.
Though if you've been cruising around the med a bit, you'll have to admit that the boats fitted with stern anchors are very rare. Not as much as a coconut in Antarctica maybe, but almost.
