1. That thing that comes with your new mast, that's a "shim". It goes on underneath the boom head and protects the mast from rubbing.
Yes I just figured that out.

No my printed indicators on the mast aren't there anymore.
No I don't really care about the indicators.

2. Marginal winds are your friend.
Go out in crappy winds to practise tacking, gybes etc. I found a great little channel between two sandbanks the other day, about 15 - 20 seconds from side to side where I
had to constantly tack/gybe.
Practise sailing about 80% of the time with one hand on the boom - I didn't realise how uncommited I really was.
Practise clew first beach/water starts - sail control. Actually I was amazed how much power is in the sail when backwards, took me off my feet coupla times in 12 knots.

And yes prepare to be addicted.
I thought that was just a humorous figure of speech. It is just like any other vice (although healthier) - arguments with family, money (bought 3rd board last night

), withdrawl symptoms, anxiety, manic highs, its own language. Help. Me.
