I learned to race as crew on another boat. Learned what I could and after 2 years started to race mine. Now I have so much silver and crystal I have no where to keep it all. My suggestion, get your sailmaker to go on a couple of races with you and point out what you are doing wrong. Make suggestions what to do right. Then go out and practice, practice, practice. Keep the crew involved and always talk up your maneuvers before you make them. After any race, get the crew together and hold a "debrief". There's lots to be learned at the debrief and everyone feels like part of the team.
