After a vigorous sail today in 45 degree weather, I noticed after pulling my mast and trailering home there were about 8 plastic ball bearings sitting in the bottom of the mast step. This probably was why furling and unfurling wasn't so smooth today.... Anyway, the bearing races appear to have some tiny minor damage on the the outer edges that is just enough have allowed a few of the the bearings to spit out. I'll probably have to buy a new bearing assembly, but just out of curiosity, how many ball bearings are there supposed to be?

I've put it all back together now and and see there are enough ball to fill up the bearing all the way around. It's about 35F out here today and the balls are very easy to pop out. I now think the issue isn't damage on the bearing races, but instead that the balls are smaller due to thermal contraction. I've stuck a pool noodle in there for now. I've got a 250 mile race coming up in April and will probably replace the entire bearing before setting out on the event.

Tell us about your race MM. Where you headed?

I've done the Everglades Challenge a bunch of times now, so this year I decided to change it up this year for a new event. I'm doing the LRR Challenge, a race from Augusta, GA down 175 miles of the Savannah river to the ICW and then 60 miles north to Edisto Beach, SC.

Thanks for the tips on the bearings. I'll take another look at them when it warms up again, it's 17F today and my interest in working on the boat is low. I still think it has something to do with the cold, since there's never been an issue with my 2015 boat before. I really want to wait until it's warmer before modifying the bearing races in any way.

You might find it worthwhile to sand out any high spots in the mating surfaces of the bearing plates. As the balls casn only fall out during transport, that pool noodle it definitely essential (everybody should use one IMHO)

Would anyone recommend using a grease or lubricant to minimise wear to these bearings?

I understand that if sand gets into there it would be more of an issue but if done sparingly...?

Your thoughts, as always, are appreciated!

Update: There are 24 balls in there.

I tried sanding the backs of bearing carriers flat, but it really doesn't help. Talking to another Watertriber, he said the delrin balls wore some on his, they are are supposed to be 0.375" new and he measured some of his at 0.372". I figure between the wear on the races and some potential wear on the balls, it would be best to just replace everything. It probably doesn't help there's some slight damage on the edges of my bearing races either. I've ordered all new everything and hopefully that will keep balls from dropping out when pulling the rig on the water to clear bridges, etc.

New bearing races and delrin balls seems to have solved my issue.
