RE: Retrieval boats?
Depending where I go & who with I use several methods. Up the river or at the races we use a small fishing boat to drive out & get them, at the local pond with others around we either walk out (it's waist deep) or use the ball on a line method. By myself I at the pond I use a method like the one impba3548 uses. At the larger ponds where it is too far to cast or use a line without getting it tangled I use the retrieval boat with the fork on the front. Sometimes I take more than one method with me & choose depending on the situation.
I NEVER SWIM.
