Fast forward 25 years, here's a video of a few Optimists racing at Rutland last year.

Optimists at Rutland
Yesterday's post Dirty Duck mentioned a little about my own sons' sailing Optimists at Rutland SC in the late 1980s.

Tillerman do you play sailx? And also, do you live in GBR or USA, it confuses me!? Loving the content :)
I live in the USA. Moved here from GBR at the end of 1988.
I used to play SailX but haven't done so for at least a year or two.
Haha, think I'm in the background at 1:35!
What did you think of Okole on SailX?!
Haha - hi Jamie!
Anonymous - when I played SailX I felt that Okole was one of the best moderators there who could usually be relied upon to decide protests correctly.
How do magnets work?
Great question. How do magnets work? Something that Optimist sailors at Rutland really need to know. Here is the best explanation I found on the Interwebs…
Around the nucleus of the atom there are electrons. Scientists used to think that they had circular orbits, but have discovered that things are much more complicated. Actually, the patterns of the electron within one of these orbitals takes into account Schroedinger’s wave equations. Electrons occupy certain shells that surround the nucleus of the atom. These shells have been given letter names K,L,M,N,O,P,Q. They have also been given number names, such as 1,2,3,4,5,6,7(think quantum mechanics). Within the shell, there may exist subshells or orbitals, with letter names such as s,p,d,f. Some of these orbitals look like spheres, some like an hourglass, still others like beads. The K shell contains an s orbital called a 1s orbital. The L shell contains an s and p orbital called a 2s and 2p orbital. The M shell contains an s, p and d orbital called a 3s, 3p and 3d orbital. The N, O, P and Q shells each contain an s, p, d and f orbital called a 4s, 4p, 4d, 4f, 5s, 5p, 5d, 5f, 6s, 6p, 6d, 6f, 7s, 7p, 7d and 7f orbital. These orbitals also have various sub-orbitals. Each can only contain a certain number of electrons. A maximum of 2 electrons can occupy a sub-orbital where one has a spin of up, the other has a spin of down. There can not be two electrons with spin up in the same sub-orbital(the Pauli exclusion principal). Also, when you have a pair of electrons in a sub-orbital, their combined magnetic fields will cancel each other out. If you are confuse, you are not alone. Many people get lost here and just wonder about magnets instead of researching further.
