I have Barient electric
winches that are starting to show their 26 years of age. I've only owed this boat for <3 years and don't know the service history
. What I've noticed is that under constant load they seem to slow down. In a perfect test yesterday my wife ran the winch
as she hoisted me up the mast
. By the time I got to top I was moving noticeable slower than when we started. I'm pretty sure I weighed the same at the top as at the bottom, and the fiction loads were the same, so I can't explain why the electric motor
would slow down. We were dockside on shore power
at the time.
Later while sailing the situation seemed similar, but in that case the load usually increased as we hardened up the main or the jib
. Nonetheless it doesn't seem right.
The winches seem to spin freely and quietly by hand, but certainly I'll do a full disassembly and cleaning
soon, but none of that effects the motor
. What can explain this? Is it a warning of bad news to come?
