If timing and strategy were simple, everyone would win every start. Actually sometimes you will see some marvelous (ahem) starts when five or six large boats all try to be in the exact same place at the exact same time. Marvelous if you're not paying the repair bills!
You might try getting the book by Dave Perry on understanding the racing rules, he goes into far more than just what the rules are. And there's another classic that I can't remember the name of...a comb-bound book that is all about strategies and especially starts...someone Black or Blackstone? (Anyone else remember which one this is?) that's also been out and revised over the past 20 years or so.
There are many strategies, many options, that's why I'd say to get the books and read them in detail.
