Over the years I've accumulated stacks of less than organized spreadsheets to track wind and weather for post race analysis, crew (plus weight), rig tune, sail usage, fleet participation, not to mention race results and season high point standings. A while ago I started trying to integrate wind, wave, crew, sail, tune, and results into one database but I only got as far as downloading wind. Didn't think to track maintenance, guess that's why I'm behind on it.
