Commonwealth Games Sailing

If you were him, would you choose to leave the RYA machine to sail for Uncle Alex?

RYA Scotland is currently a sort of "Super Zone" of the RYA- mainly functions as with the English zones, but with some additional responsibilities devolved to it. Think Northern Ireland and Wales are similar.

Kneewrekcer is right, the main part of the independence movement (or at least Wee Eck and his coterie) are fervent monarchists who seek to repeal the union of the parliaments (where England bailed out a bankrupt Scotland following a disastrous attempt to colonise what is now Panama) but not the union of the crowns (where a Scottish monarch realised he had the best claim to the English throne and promptly sat on it).

In practice, I reckon what would therefore happen is that RYA Scotland would become a wholly separate organisation. Perhaps renaming itself as SRYA? It would certainly become a full MNA. I'd assume the rest of the UK (rUK) would continue to use GBR for sails, whilst Scotland would almost certainly go to SCO. rUK sailors would continue to be welcome at events in Scotland and Scottish sailors at evens in rUK. It would mean though that whilst SCO sailors would be able to race at a GBR Nationals, they would not be eligible for the title (it's not unheard of for European and even further afield sailors to sail at a UK nationals or vice-versa).
