Two sailing seasons ago I went through the same thing. Since most of my sailing is single handed I wanted the convenience as well as safety when the weather gets rough. I bought a furlex furler and a new North Sails 150% headsail. It has worked excellent with no problems in two seasons. At the same time I bought new Harken self tailing Jib sheet winches. With all these upgrades my boat is a pleasure to sail. If the wind is up and I'm feeling lazy I won't even bother with the main sail because my boat will sail at hull speed very well just on the Jenny. Another factor on the plus side for me was that I had intended to keep this boat. Now that I spent all this money I have to keep the boat because I'd never get the money back if I were to sell.
