standing on ur line over a mussel bed!
Ouch...... No matter how cheap your line is get yourself a line tray or even better do what I do.
Get yourself a plastic dish washing tub (about 18" square) in a hardware store. They cost about €4
Get yourself an old belt.
Drill some holes in the bottom with a 8mm drill bit. One hole in each corner and 4 in the middle should be plently.
Now drill yourself the belt holes in the side of the tub. These need to be about 10 " apart.
Using the 8mm bit again drill a hole and move the bit up and down to make a vertical slit in the tub. Make the second slit the same height as the first.
Put your belt through and strap it around your waist. Now catch some fish without trashing your line.
