I write a blog on my Solo sailing. I'm afraid it won't help you if you are a top sailor - it is written from my perspective as a club sailor getting used to his Solo (had a Solo for about a year now). But if you like to read about random thoughts on mast rake, sails, fittings and my various experiments you can find it here:
Solo Scribbles
Any other Solo bloggers out there?
Just caught up with your last few blog posts. Interesting to see your new sail.
