Custom Boat Parts | Marine Parts & Engine Components Made to Order
Manufacturing
Turning your ideas into 3D CAD files, 3D prints, prototypes and 1000s of manufactured parts for more than 19 years!
If you’re looking to make your boat more personal, more functional, or just easier to use, or to sell a custom boat accessory idea on a wider scale, you’re not alone. Whether you’re swapping out worn parts or adding something new, custom boat accessories can make a big difference. If you’re ready to go from idea to creation, our expert team here at J–CAD Inc. will help you at every step along the way.
We help boat owners (from weekend fishers to charter operators and everything in between) to make the gear they can’t find in stores. You can bring a sketch, a broken part, or just a wish list, and we’ll help you design and manufacture it from scratch in the most appropriate manufacturing format, eg. 3D printing, CNC machining, or injection molding. Our customers choose us because we work fast, keep it affordable, and don’t care if you want just one piece or one hundred. We’re engineers who know what works on water.
Why’s that important? Because boats live hard lives. Salt, sun, wave impact, vibration. Off-the-shelf gear rarely holds up well. Our parts are designed to fit your space, your layout, and your conditions. Whether you’re dealing with aluminum hatches, console mounts, rod storage systems, or one-off duck boat upgrades, we’ll help you personalize it and make it real.

Every boat is different. So are the people who use them. That’s why we help you build what fits your boat, your space, and your routine on the water. Here’s how different owners choose what to make, and how custom parts can change the way their boats work.
Pontoons are all about comfort, so the best upgrades tend to focus on space and style. You can personalize seating arrangements, storage modules, drink holders, even boarding steps. Some customers add retractable sunshades or custom rails for easy boarding, or you can just add aesthetic upgrades.
Popular custom pontoon items:
Many of these accessories are made with marine-grade aluminum, plastic, or powder-coated steel. They’re lightweight and last longer in sun and spray. If you’ve got a weird shape or tight gap to work with, we’ll help you design around it.
If you’re serious about fishing, your boat’s not just a boat, it’s your tool (and maybe even your home!). Most customers want to make their own tackle management systems, livewell upgrades, or modular storage trays that actually match their gear.
Top fishing boat upgrades we can build:
These systems aren’t just cool to look at. They stop gear from bouncing around while underway and help serious anglers stay organized under pressure.
Bass boat owners want speed and precision. Custom bass accessories usually involve tournament-ready mods like camera mounts, recessed foot pedals, or flush hatches.
Some possible examples include:
You can personalize these parts with non-slip textures or logos, depending on how you want it to look.
Duck boats are rough, rugged, and need to stay silent and solid in bad conditions. Customers might be looking for aluminum parts that won’t rattle or rust.
We can make:
Durability matters. These accessories can get made with thicker-gauge aluminum and tight tolerances. They’re built to stay quiet when it counts.
This overlaps with everything above but aluminum deserves its own mention. Custom aluminum boat accessories are strong, light, and corrosion-resistant. They’re perfect for both function and style.
We can make things like:
Whether you’re fishing, living or just cruising, we’ll help you personalize your aluminum boat with parts made to last through years of use in the water.
For some customers, it’s about function. For others, it’s about identity. But most want both. A custom part doesn’t just make your space more usable, it makes it feel like truly your boat.
Names, logos, colors, these are the things people ask for when they want their boats to be personalized and to stand out. The simplest upgrades can give a boat real presence without blowing the budget.
Popular personalization requests:
Some people even add boat names to seat risers or speaker covers. It’s your layout, your style, your call.
If you’re selling a product, you may also like to add your logo for brand recognition.
Personalization also often solves problems that off-the-shelf accessories don’t. Want a storage drawer to hold a specific lure case? Done. Need a rod holder to fit your exact trolling setup? Easy. Want a control panel that actually makes sense for how you fish? You can make it.
At J–CAD, we help customers personalize the perfect accessory by working backwards from how they actually use their boat. Some want faster rigging. Others want cleaner wiring or drier storage. No matter what you’re after, you can choose to make exactly what works for you.
And because we make everything in-house, it’s easy to match your gear across different custom boat systems. You can go from a simple drink holder to a fully kitted layout, one item at a time, over time.
You can’t use indoor gear on the water. Salt, UV, spray, and waves impact will destroy anything that’s not built right. That’s why we help you choose the right material for every part you want to make.
We mostly work with these:
| Material | Why It Works on Boats | Used For |
|---|---|---|
| Aluminum (anodized) | Lightweight, corrosion-resistant, weldable | Rails, hatches, mounts |
| HDPE (marine plastic) | UV-stable, waterproof, won’t rot or rust | Storage trays, tackle drawers |
| Stainless steel (316) | Saltwater-safe, high strength | Hardware, brackets, hinges |
| Acrylic / Lexan | Clear, rigid, strong | Instrument covers, livewell lids |
When it comes to custom marine parts and accessories, the biggest question isn’t just what to make, it’s who’s actually going to make it right. We talk to a lot of frustrated customers. The kind who tried ordering from Amazon or Aliexpress, got something that “kinda fits,” and ended up junking it after one summer.
That’s where J–CAD Inc. comes in. We’re not a shop. We’re not a drop shipper. We’re a full CAD-design-to-part service, and we make the perfect custom boat parts in small or large batches.
Anything from one unit to 10,000 or more! No job is too big or small.
Our customers get great parts, made fast, with no drama. That’s why people trust us. We also provide great customer service, as can be seen from our reviews.
Most people assume that anything labeled custom means expensive. That’s not always true. We’ve made single parts for as little as a couple of hundred dollars. It depends on the size, material, and how you want to make it.
Here’s what drives the price up or down:
Here are just some of the types of accessories we can make. But if you don’t see what you’re looking for here, ask us if we can help! Chances are we can.

Off-the-shelf parts don’t always fit. Big suppliers don’t always care. But you still want your boat to run better, feel better, and look right. That’s where we come in.
At J–CAD Inc., we help you make the exact boat gear you need, whether it’s one small bracket or a full storage system. You choose the function, the fit, and the finish. We do the rest.
