To enable KayaArm use in salt water we use stainless steel bolts, galvanized chain and a 6061-aluminum alloy for the bulk of the device. The aluminum alloy has good saltwater resistance and should be good for many years in both fresh and salt water.
Feedback on KayaArm purchased in 2013 in salt water:
Hello, thank you for your follow up. The KayaArm is doing fine. As expected I do have growth on the portion of the frame that is below the tide line but not an issue. No indication of corrosion, I am very happy with it and certainly feel free to share my email to interested customers.
