When riding waves, it doesnt matter as close to shore and you have to ditch the kite anyway.
When riding twintips you are not far out either, so not an issue here.
Then we have raceboards and trips - and here it can make a difference, true.
But I still say "let the kite be a lost kite" in the very rare case it happens.
We have land close by no matter where we go, as we are surrounded by bays and small beaches etc, all over - so not an issue really, not even on a raceboard a bit out.
Curious - why do some want to ride far away from the shore ?
But some has a very different coastline and wind conditions, I know, so maybe necessary ?
