Fabrications Made for Coastal Conditions

Every boat is different—and a good fabricator knows how to build around that. Whether you’ve got a tinnie, a trailer boat or a serious offshore rig, marine fabrication is about getting the right fit and finish for the job. That means matching tank capacity to hull shape, adding bow rails that flow with the boat’s lines or reinforcing a trailer without adding unnecessary weight.


Bait tanks, water tanks, rod holders, ladders, canopy frames—each piece is measured and made to fit the boat you’ve actually got, not some generic plan.


It’s all welded with precision using corrosion-resistant materials, so it holds up through years of sun, spray and launch ramps. Custom finishes like powder coating or polished stainless give you the look you want with the strength you need.


Built to fish. Built to last.

Bait Tanks

A good bait tank keeps your live bait healthy and within reach. We custom-build bait tanks to suit your vessel’s size, layout and fishing style. Whether you need a compact in-deck unit or a full transom-mounted setup, it’s fabricated from marine-grade aluminium or stainless steel and plumbed exactly how you want it. Lids, baffles, fittings—it’s all part of the build.


Tanks are made to handle salt, impact and constant movement without leaks or wear. If you fish regularly, a proper bait tank makes a huge difference. Built tough, built clean and made to last on the water.

Fuel Tanks

Marine fuel tanks need to be built right—there’s no room for leaks, swelling or poor fit. We fabricate custom tanks using marine-grade aluminium or stainless steel, shaped to fit your boat’s hull and storage space exactly. Each tank is pressure-tested, fitted with clean welds and built with the correct ports, mounts and baffles.


Whether you’re upgrading, replacing or building from scratch, a custom tank offers peace of mind and performance. Designed to meet safety standards and handle harsh marine conditions without cracking or corroding. Ideal for boats big and small, commercial or recreational.

Water Tanks

Clean water’s essential out on the water—so your tank needs to be reliable, lightweight and rust-free. We custom fabricate marine water tanks from food-grade stainless or aluminium to fit snugly into under-deck compartments, storage areas or wherever space allows.


Each tank is welded for strength, with fittings placed exactly where you need them for easy filling, drainage and access. Whether you’re cruising, camping or working offshore, a custom-fit water tank gives you fresh storage without wasted space or extra weight. Built to hold shape, resist corrosion and keep your water clean every trip.

Bow Rails

Bow rails do more than frame your boat—they keep you safe on deck in swell, spray and chop. We custom-build bow rails from polished stainless or aluminium, shaped to match your boat’s lines and height preferences. Whether you want a low-profile setup or full wrap-around protection, every rail is fabricated with clean welds, smooth bends and strong mounts.


Rails are measured to fit tight, stay secure and look sharp. We also offer integrated rod holders, anchor guides or support frames depending on your setup. It’s all about safety, functionality and a finish that lasts.

Frequently Asked Questions

  • Why is stainless or aluminium used in marine work?

    Stainless steel and aluminium are both corrosion-resistant, making them ideal for salty, wet environments.


    Stainless is tough, polished and great for visible fixtures like rails or ladders.


    Aluminium is lightweight and doesn’t rust, so it’s often used for structural elements like tanks or boat trailers.


    Both can be welded cleanly and built to last with minimal maintenance.

  • Can I get custom tanks made for my boat?

    Yes—custom tanks are one of the most common requests in marine fabrication. Whether you need a bait tank, water tank or fuel tank, these can be shaped to fit under decks, in tight corners or along specific hull lines.


    A qualified boilermaker can add baffles, inspection ports, drain fittings and other features to suit how you use the boat.

  • What are bow rails and why are they important?

    Bow rails are safety features installed along the front deck of a boat. They help prevent people from falling overboard and offer a sturdy handhold when walking forward in rough conditions. They also add to the boat’s look and structure.


    Properly fabricated bow rails are strong, securely mounted and shaped to match the lines of your vessel for both safety and aesthetics.
