I've done up a demo video on how I install spray chines.
This particular clip shows how its done on an older 4.55.
There is a bit of tweaking from a 450 template and the end result is a nice matching contour to suit.welding is currently in Brisbane and can come install a set in your shed or driveway 😎

This video showcases the complete process of fabricating and plastic extrusion welding custom spray deflectors (chines) onto a Polycraft boat.

The vessel is manufactured from rotomoulded LDPE (Low-Density Polyethylene), a highly durable and impact-resistant material that allows for a range of structural modifications. In this demonstration, we design, fabricate, and weld new spray deflectors to enhance ride quality, reduce water spray, and improve overall on-water performance.

From preparation and fit-up through to final extrusion welds, this video highlights the techniques, equipment, and attention to detail required to achieve a strong, clean, and long-lasting result.

Did you know...
We use the same UV-stable polyethylene as the Polycraft hull for spray chines?
That means a perfect match and welds that last!
