Don't get the computer edition, buy the book - computers have a tendency to crash in salt water environments - this is a book you will carry on board cruising (there are other books, perhaps someone else might recommend one - this happens to be the one I have used for years.) This lays out the traditional routes from point "A" to point "B." The 7th edition has been updated with very recent pilot chart data (you will learn about pilot charts at some point.)
Consider getting a copy of Virtual Passage Planner. Link to free trial download Visual Passage Planner 2.1 Download (Free trial) - VPP2.EXE
This is a software program that lets you define your own routes. It then applies average wind and average current vectors (by month) and tells you how fast you will go, how long the trip will take, and how much time you will spend going upwind, reaching, and running.
Unlike the Interstate highway system where you just put the petal to the metal and go the speed limit (or a little above) sailing routes turn the ocean from one big blue thing into very specific places to be and to not be. This is because of the "bands" of wind from the equator to the poles - Intertropical Convergence Zone, Easterlies, Doldrums, Westerlies, etc. There is a great marine weather book by Steve and Linda Dashew called Mariners Weather Handbook that explains all this. You can download it for free!!! at http://setsail.com/mwh.pdf
Finally, spend some time on Noonsite - http://www.noonsite.com/. This site was started based on the work of Jimmy Cornell (the guy who wrote World Cruising Routes.) It is a great site to get very current country information. This can be critical to your budget. Checking into one country might cost you $500 while the next island might be $10. Good stuff to know.
Best wishes as you plan your adventures...
