Custom Boat Accessories: Personalized Gear for Your Yacht, Fishing, Pontoon & Duck Boats
Manufacturing
Turning your ideas into 3D CAD files, 3D prints, prototypes and 1000s of manufactured parts for more than 19 years!
When you can’t find the right boat part, or when nothing off the shelf fits your system, you need a manufacturer who gets it. That’s where we come in! We help boat owners, small marine businesses, and DIYers build custom parts using CAD Design, 3D Printing and other types of manufacturing that actually work. Whether it’s a one-off motor mount or a full set of replacement brackets, or a custom production run we can solve any marine part problem!
We specialize in small to medium batches, not just bulk orders. So if you’re restoring an old hull, fixing up a busted steering system, or replacing discontinued marine parts, we can design it, fabricate it, and ship it. It will be fast. It will be affordable. And you’ll get the exact shape, fit, and function you need.
If that sounds like what you need, fill out our quote form, or give us a call on 1-888-202-2052 and let’s talk about what you need.
J‑CAD Inc. builds custom boat parts that fit exactly. No compromises, no guesswork, no re-drilling etc.
We can replace hard-to-find or discontinued parts using CAD, CNC, 3D printing, molding, or welding depending on what the system needs.
Materials matter. Know when to choose from aluminum, fibreglass, plastic, or steel, depending on stress, corrosion, and install location.
We work with all boat types including jet, drag, and racing boats and can create parts that help improve both performance and reliability.
The process to get started is simple. Send photos, sketches and measurements, we handle the questions, design, prototyping, and fabrication.
Most generic boat parts don’t work the way you want. You try to switch something out, and it doesn’t line up. The holes are off. The material corrodes. It rattles like hell. Doesn’t matter if it’s a console panel, a substitute bracket, or a trim tab. When the part’s wrong, your boat will suffer.
Here’s how custom boat parts save you time:
No return shipping or trial-and-error installs
Fewer tools and hacks needed to “make it work”
Fits your layout, not someone else’s idea of “standard”
When it comes to boat parts, material isn’t just a detail it’s really important. The wrong part can fail fast, especially if it lives in saltwater. That’s why we give you real options: aluminum, fibreglass, or welded assemblies based on what your system actually needs.
If you’re dealing with stress points like seat mounts, jack plates, or motor brackets, go with marine-grade aluminum. It’s light but strong. It can handle vibration and exposure. If you need something molded, seamless, and watertight like on hatches or fairings then fibreglass is a solid pick. And for structural mods or tough locations (like mounting in tight spots), we can weld parts to match your hull shape exactly.
Here’s a quick breakdown:
| Material | Best For | Strengths |
|---|---|---|
| Aluminum | Brackets, mounts, support frames | Corrosion-resistant, light, durable |
| Fibreglass | Covers, panels, interior inserts | Moldable, smooth finish, non‑conductive |
| Welded Steel | Structural mods, heavy load zones | Rock solid, precise fit, no fasteners |
Performance boats push everything harder. You’re not just cruising. You’re hammering the throttle, cutting wakes, running tight. Whether it’s a jet intake, a drag trim tab, or a reinforced steering system, off-the-shelf gear won’t cut it.
J‑CAD works with speed-focused setups. We’ve built custom parts for river runners, sprint jet boats, and lake racers. Every build is a little different. Some people need to swap a motor mount to clear their fuel system. Others are hunting for a better angle on their transom plate. Some just want a clean way to house electronics without overheating.
Stuff we can help with:
High-load steering brackets
Custom-fabbed jet nozzles and duct plates
CNC-machined trim tabs for drag boats
Engine covers and airflow mods
Lots of people come to us because the part they need doesn’t exist anymore. Either the brand’s gone. The model’s out of production. Or the substitute part they ordered looks right on paper but doesn’t line up once they have it.
We can rebuild any boat part from scratch. Seat hinges. Throttle linkages. Switch panels. Steering hubs. Sometimes we reverse engineer from a busted part. Sometimes we just work off measurements.
We’ll ask for a few photos or sketches. Then we model it and walk you through any questions about installation or finish. You’ll know what you’re getting. And if you ever need a replacement down the line, we’ve got the CAD file saved already.
You’ve got a busted bracket, a weird gap on your dash, or a half-rusted mount that needs reworking. Here’s how we take that and turn it into a working part you can actually use.
You send the details. A rough sketch. A broken part. Photos. Etc. We’ll look at what you’ve got and ask any questions we need.
We build the CAD model. We use solid modeling software to replicate or improve your design.
We prototype if needed. For some parts, especially more expensive ones, we might 3D print a test version (especially for fit checks).
We machine or fabricate. CNC, welding, 3D printing or molding—whatever makes sense for the system and your timeline.
You get the finished part. It arrives ready to install.
We don’t lock you into anything. You get the CAD file if you want it. You can reorder or tweak the part later. And because we’ve already built it once, the lead time on a repeat is fast and cheaper. We can also mass produce your parts.
This process is built for people who care about their boat. They don’t just want to keep it afloat, but care about making it better.
If you’ve got a boat part that’s cracked, missing, or just never fit right, stop wasting time trying to force it. We can build a custom alternative that works.
Here’s what to send:
Photos from a few angles (even better with something for scale)
Rough measurements or dimensions
Any notes about what’s not working or what needs to change
You don’t need to draw up plans. We’ll ask the right questions and build out a CAD file from your info. If you’re not sure what material works best, just say that. We’ll walk you through options like aluminum, plastic, fibreglass, or welded steel based on the load, exposure, and part type.
We keep it simple. Fast quotes, direct answers, and short lead times.
Ready to get started? Contact us here or call 1-888-202-2052 and tell us what’s going on with your boat. We’ll help you get you the part you actually need.

We recommend you hire J-CAD Inc. Alternatively, marine outfitters like West Marine, Defender, specialty fabricators, local machine shops, and online platforms like Boat Builder Central accept custom orders.

Yes. They cost more due to design labor, materials, and one-off fabrication. Some sources estimate 2–4× the price of standard parts.

Yes. When original parts are discontinued, fabricators can reverse-engineer replacements using precise dimensions, templates, or damaged samples.
