When it comes to boating comfort and functionality, it’s the little things (like seat slides) that make a huge difference. Whether you’re replacing a worn-out slide, upgrading your helm seat, or retrofitting a classic Tiara or Pursuit, choosing the right seat slide kit matters.
At DE Marine, we carry UHMW seat slide kits in 6", 7.25", and 8" lengths. But how do you know which one you need?
Let’s break it down so you can make the right call and get back to smooth waters.
What Is a Seat Slide and Why Does It Matter?
Seat slides are the gliding rails underneath your boat’s seats. They let you adjust the seat forward or backward so you can reach the helm controls, sit comfortably, and stay secure when you're navigating rough water.
The right seat slide makes your time on the water safer, smoother, and more ergonomic. The wrong one? It could lead to misalignment, limited movement, or unnecessary repairs down the line.
So… 6", 7.25", or 8"? What’s the Difference?
| Seat Slide Kit | Tiara OEM Part | Price | Common Fit |
| 6" Kit | 5334450 | $56.00 | Tiara Yachts or Pursuit Boats |
| 7.25" Kit | 5320097 or 5320669 | $70.00 | Tiara Yachts or Pursuit Boats |
| 8" Kit | 5334850 | $78.00 | Tiara Yachts or Pursuit Boats |
All our kits include high-strength UHMW slides (ultra-high molecular weight plastic), known for their low friction and high durability, perfect for marine environments where salt, sand, and sun are constantly at play.
Pro Tip: If you're unsure which Tiara part number you’re replacing, check the bottom of your seat mount or reference your boat’s original build sheet.
Not Replacing an OEM Part? Here’s How to Measure:
If you’re retrofitting or building custom, here’s how to size your seat slides:
- Measure the current slide track length from end to end.
- Confirm bolt spacing our kits are pre-drilled for common Tiara and Pursuit hole patterns.
- Check clearance make sure the seat can fully slide without hitting consoles or bulkheads.
Still unsure? Snap a photo of your current setup and send it to our team. We’re always happy to help you confirm the best fit.
