Seems that more than a few are having problems with plastic/teflon bearings- Has anyone just tried (marine) grease? I have and it can be kind of messy if too much is used but seems to work just fine. It can be easily wiped out after takedown and reapplied fresh so I doubt that attracting sand, etc. will be a big problem.

Is this some sort of hallowed tradition from the days of Hobie Alter or is there a definitive reason that it is not done?

Not everyone takes their mast down after every sail. Hobie developed something that's not messy and relatively long lasting if you get it centered in the cup.

Grease is not recommended. It won't prevent metal-to-metal contact when the fit between the pieces is imprecise (like the mast base / step). You'll grind down the mast base.

Multiple, partly worn bearing chips are OK.

For the Delrin bearing, you need to drill a hole in the top of the dolphin striker post to hold it in place.

I've sailed my 14t with the same teflon chip for 10+ years.

My 16 is running on a chip cut from a pool chlorine drum.

Works exceptionally well.

Hobie in Australia wants just too much money for any part.

Get a bag of golf whiffle balls and cut them in half. Put one in the mast step cup. It fits like it was made for it and a whole bag of these balls is $1.95 at Walley's.

I saw this on some forum and it works like a champ.
