A large miyoshi is mounted on the stem of hobikisen . The name miyoshisen was derived from this.
Since Lake Kasumigaura is shallow, even a small wind can generate waves. A wind is good for hobiki fishing. But fishermen have to row the boat against the wind to set it adrift. The boat moves forward with beating the wave on and off because the distance between the waves on Kasumigaura is shorter than that on the sea and the boat cannot ride on the wave. The impact of the wave cannot be compared with that on the sea. A large miyoshi is used to cut through such waves.
