Congratulations on your new boat and welcome to the forums. This forum acts in place of a listserv so that all questions are automatically archived here. You can opt to monitor the forums and have new posts/replies automatically emailed to you similar to a traditional listserv. To turn on tracking, click on the My Settings icon (it looks like a gear) on the Forums page. Then click to expand the Tracking/Subscription settings. You can choose the forums to monitor and the email format you prefer.
This site is not just about racing and there are many Cal 20 owners who monitor the forums that cruise their boats, including Robert Crawford, who just sailed his Cal 20 from San Francisco to Hawaii. I'm sure they'll be happy to help you out.
Good luck!
