Hi North and welcome to "Real" boating
First thing you need to know is lookout for power boaters. They think they own the water... Ok ok ok I''m just kidding...
I don''t know alot about any daysailers but sail is saing. In the size of boat you can experiment and learn alot and you can get some lessons. Like anything new you have ever done you have to do it and do it alot before you really learn how.. Good luck good sailing and look out for those powerboaters...
