Using a Dredge Boom for Marlin Fishing in Perth, Western Australia
Using a Dredge Boom for Marlin Fishing in Perth, Western Australia
For serious offshore anglers chasing blue, black and striped marlin off the Western Australian coast, running a dredge teaser has become one of the most effective ways to raise fish and convert window shoppers into aggressive biters. A dredge boom is the key tool that allows anglers to safely and efficiently deploy these high-visibility teaser systems without cluttering the cockpit or compromising boat handling.
In Perth and across WA’s game fishing grounds — from Rottnest to the continental shelf and north into Exmouth waters — dredge systems are becoming a standard part of a well-set marlin spread.
This guide explains how a dredge boom works, why it’s so effective, and how Perth game fishers can use one to dramatically improve their marlin success.
What Is a Dredge Boom?
A dredge boom is a heavy-duty outrigger-style pole mounted to the transom or gunwale of a boat, designed specifically to tow dredge teaser systems safely and efficiently. Unlike standard teaser cleats or rod holders, a dredge boom:
-
Keeps dredges positioned away from prop wash
-
Reduces cockpit clutter and line tangles
-
Provides lifting power for retrieving heavy teaser rigs
-
Improves teaser presentation and tracking
Because dredges create significant drag — especially multi-tier bait dredges — a dedicated boom prevents unnecessary strain on rod holders, cleats and crew.
Why Dredge Teasers Work So Well for Marlin
Marlin are highly visual predators that respond strongly to the illusion of bait schools. A dredge teaser creates exactly that — a dense, moving bait ball that mimics panicked baitfish beneath the surface.
Off Perth, where bait concentrations can be scattered and water clarity is often excellent, dredges help:
-
Pull fish up from deeper water
-
Hold marlin in the spread longer
-
Increase teaser-to-lure conversion rates
-
Trigger aggressive feeding behaviour
Many WA game boats report that dredges dramatically improve bite window conversion, particularly when fish are present but not actively feeding.
Benefits of Running a Dredge Boom in WA Conditions
Western Australian offshore conditions can vary from glassy calm mornings to afternoon sea breezes and sloppy cross swells. A dredge boom provides major advantages in these conditions:
1. Cleaner Teaser Presentation
Positioning dredges away from prop turbulence keeps them swimming naturally and prevents unnatural spinning or collapse.
2. Improved Crew Safety
Heavy dredges retrieved from rod holders can be awkward and dangerous. A boom allows controlled lifting and easier clearing when a marlin enters the spread.
3. Reduced Cockpit Chaos
During a Perth marlin bite — especially double or triple fish days — cockpit space is critical. A boom keeps teaser lines out of the way when clearing the spread.
4. Ability to Run Larger Dredges
WA’s large bait schools and big predators often respond better to bigger teaser profiles. A boom allows anglers to comfortably run multi-tier or heavier dredges.
How to Set Up a Dredge Boom for Perth Marlin Fishing
Positioning
Mount the dredge boom so the teaser runs just below the surface, typically between the short and long corner positions.
Teaser Distance
A good starting point is 5–10 metres behind the boat, deep enough to create a convincing bait ball but close enough for effective switching.
Dredge Types That Work Well in WA
Perth anglers commonly use:
-
Natural bait dredges (mulies, scad, bonito strips)
-
Artificial mullet or squid dredges
-
Strip teaser dredges for added flash and vibration
Natural tones often perform well in WA’s clear water, while high flash teasers can be effective during low-light or dirty water conditions.
Tips for Perth Game Fishers
Match bait profiles — Use teaser styles that reflect the bait species currently holding offshore.
Run teasers consistently — Even on quiet days, dredges can be the trigger that raises a curious fish.
Watch your sounder — Dredges are especially effective when bait is holding mid-water rather than on the surface.
Practice clearing drills — Efficient teaser clearing dramatically improves hook-up rates when switching fish onto lures.
Choosing the Right Dredge Boom and Gear
When selecting a dredge boom for WA offshore use, look for:
-
Strong mounting hardware suited to offshore loads
-
Corrosion-resistant construction
-
Smooth lifting and retrieval capability
-
Compatibility with electric teaser reels if upgrading later
Because dredges generate serious drag, investing in quality gear prevents failures and improves long-term reliability.
Final Thoughts
For Perth and Western Australian marlin anglers looking to elevate their spread and improve teaser performance, a dredge boom is one of the most effective upgrades available. By creating a realistic bait ball and improving teaser management, dredges consistently raise more fish and increase conversion opportunities.
Whether you’re fishing Rottnest waters, pushing wide of the shelf, or heading north for extended game fishing trips, a well-run dredge system can be the difference between seeing fish and catching them.
