J Clarke Marine Ltd Canopy fasteners and Stainless fittings

Suppliers of Canopy fasteners and Marine Stainless steel fittings JClarke Marine is a small but expanding company run by my wife and I.

Having been brought up in a boating family I was soon introduced to the many joys of the great outdoors and I have always held special affection for Strangford Lough in particular. An early interest in boating was fueled by my Granda, Albert Clarke, who established a sterling reputation throughout Northern Ireland and Ireland from a successful marine shop & showroom in Comber, County Down. One thi

ng lead to another and I found myself designing and manufacturing boat canopies all over Ireland, during which I quickly learnt about the different types of fasteners and fittings used in cover making and the expertise gained from this experience provided me with a keen understanding of the products customers need. In August 2011 I set up JClarke Marine: an online store to supply the end user with fasteners and fittings they may find hard to source. Every month I look at sourcing new products and making them available to you, so please watch this space! With over thousands of customers so far, we try our best to provide an excellent service as we value our customers greatly. All items are posted first class (within the UK) on a regular basis throughout the week. Please take your time to browse our website; it is relatively new but fully functional! Regards

Paddleboarders!
A couple of great reviews recently from customers using One Seal on their paddleboards 👍

One customer had an air leak around the pump valve and after two coats of One Seal it was holding air again the next day.

Another used it to attach D-rings to their paddleboard and has since had it out in both the sea and river with everything still holding strong.

This is where One Seal really comes into its own. It can get into those awkward areas around valves, seams and fittings where putting a normal repair patch on can be difficult.

No patch needed, easy to keep in with your paddleboard gear and handy to have there when you need it.

If you're in any paddleboard or SUP Facebook groups, we'd really appreciate you sharing this post. We're a small husband and wife business and recommendations like this genuinely help us get One Seal in front of more people.

Ireland has always felt like a second home to us.

Long before J Clarke Marine became an online marine hardware supplier, I spent years travelling all over Ireland making and fitting bespoke boat covers.

From marinas in Malahide, Howth and Dún Laoghaire, to boats along the River Shannon from Portumna right through to Enniskillen, I had the privilege of working with hundreds of boat owners and meeting some fantastic people along the way.

Those years gave me a real appreciation for Ireland's boating community, and many of those customers are still with us today.

Today, J Clarke Marine is a family-run business based in Northern Ireland. While we're no longer travelling the country fitting covers, we're proud to supply quality marine fasteners, stainless steel hardware and boat fittings to customers across the whole island of Ireland.

🚚 1–2 working day delivery across Ireland
📍 Dispatched from Northern Ireland
⚓ Trusted by thousands of boat owners, marine businesses and canvas makers

Whether you're maintaining a cruiser on the Shannon, fitting out a yacht in Cork, repairing a cover in Donegal or working on a fishing boat in Galway, we're only a day or two away.

💚 A small favour...

If you're a member of any Irish boating Facebook groups, marina pages, yacht clubs or local community forums, we'd be incredibly grateful if you could share this post or recommend J Clarke Marine when someone is looking for marine fittings.

As a small family business, your recommendations genuinely mean more to us than any advert ever could.

Thank you to everyone across Ireland who has supported us over the years. We look forward to serving the Irish boating community for many years to come.

DAY 28 UPDATE – SALT WATER CORROSION TEST

28 days submerged in salt water and the difference is becoming hard to ignore.

The cheap imported turnbutton continues to show heavy corrosion around the base stud, with white deposits, dark discolouration and visible deterioration developing over time.

In comparison, the genuine DOT turnbutton remains remarkably clean, with no significant corrosion visible.

This is an extreme test with both fasteners fully submerged in salt water 24/7 – far harsher than normal marine use – but it's a useful way to compare long-term material and plating quality.

Just 2 days left until the final 30-day results.
Which one would you trust on your boat?

⚠️ DAY 21 UPDATE ⚠️
Three weeks into our 30-day salt water corrosion test and the differences are becoming increasingly obvious.

The budget turnbutton has continued to deteriorate, with heavy corrosion deposits now surrounding the stud. Underneath these deposits, the stud has turned black and corrosion staining is becoming visible on other components.

Meanwhile, the genuine DOT turnbutton remains clean and shows no obvious signs of corrosion despite being exposed to exactly the same conditions.

Before anyone comments, this is NOT normal marine use. Both fasteners have been fully submerged in salt water 24 hours a day since Day 1, making this a much harsher test than most real-world marine applications.

Same salt water. Same container. Same duration.
Very different results.

Only 9 days remaining until the final Day 30 update.
What do you think the cheap turnbutton will look like by the end of the test?

⚠️ Day 14 Update – Salt Water Corrosion Test ⚠️

Two turnbuttons. Same salt water. Same conditions.

Fourteen days ago, we fully submerged a budget turnbutton bought online alongside a genuine DOT turnbutton to see how they would cope with prolonged exposure to salt water.

The differences are now becoming much more noticeable.

The budget turnbutton has developed significant corrosion around the stud, along with new rust-coloured spots appearing on other components. Meanwhile, the genuine DOT turnbutton remains clean with no obvious signs of corrosion.

Before anyone points it out, this is NOT normal marine use. Both fasteners are being fully submerged in salt water 24 hours a day, making this a much harsher test than most boat covers, canopies and marine canvas applications will ever experience.

However, both fasteners are facing exactly the same challenge.

We're now halfway through the test with 16 days remaining. It'll be interesting to see what they look like by Day 30.

Would you trust the cheaper option on your boat?
