the golfball effect
Posted: September 4th, 2016, 10:32 pm
I was looking at a golf ball the other day, wondering about all those dimples. I'd love to see the machine that makes them.
Then I started thinking about the use of the dimples. It has something to do with creating turbulence to reduce drag. I guess it works, you don't see any smooth golf balls?
So then I'm looking at my hulls. When I painted them, I went all the way around. Why not, it's a slick surface, it should slide real nice. I wouldn't dare slide it up on a sandy beach. Yeah, I know, beach cat, but those scuffs take forever to repair.
Well, maybe that's why they put bottom paint on them?
Now, I have a big boat, and I understand about bottom paint for protection, so I always figured they put that stuff on because they're to lazy to take it out of the water over night? But bottom paint isn't smooth, it's kinda dimply.
Anybody play golf?
