Mulloways love to feed in gutters running parallel to the beach. Gutters are simply deeper areas of water along the coast. Gutters are not unusual or special. You’d be surprised how much surf beach has a slightly deeper area running parallel to the beach. It’s not amazingly deep or particularly significant. You’ve probably swam in gutters and noticed the water depth becoming slightly shallower as you go further from shore. To find a gutter, look for deeper, darker water, and areas where breaking waves reform and become flatter and wider. Gutters can be right on the shore, surprisingly close, and can also be further out at a distance that is too far to cast to. Find a gutter you can cast to, and target it with your casts. Doesn’t have to be right in the deepest part. Also try closer to the shore and try further away from the deepest point.
