Oddly enough my boat drifts faster with the drogue from the bow, which is the highest part of the boat. On a shallow windswept lake I fish in Brittany, I opt for a bouncing anchor used like a drogue. Iron ball, length of chain and rope. No good on deep rocky lochs though.
It works well on the grassy, muddy lake bottom and fish lying in shallow water near the bank can be approached with stealth. On a longish anchor rope it is possible to cover a lot of water as the boat swings slowly around in an arc. When the arc is completed a sharp tug on the rope releases the iron ball and the boat drifts towards the bank a few yards, before another arc is covered. This is not possible when the wind strengthens though. OK not purist but it works on this difficult lake
I usually fish alone on this 1000 acre Breton lake where the fish are in small pockets. It is not often that a productive drift can be set up along a bank ( most fish are close in) so a different approach has been necessary.
