Woke up this morning at anchor and went for a sail back to the harbor under jib alone purely out of laziness. Probably 14 knots of wind. I have no problem sailing to weather under jib alone, but she sails better with the main. As the wind increases, I furl the jib trying to keep as much main as possible. Then I will reef the main.
I bet you are not properly positioning your lead block for your jib which gives you a terrible sail shape making it hard to point high.
