Snuffers! yes most cat's use them (instead of bag launching).
there are 2 different kinds that are common, mid pole and end snuffer. Most use mid pole snuffers now..
I believe the end pole system allows you to go more around a mark (during racing) and gives a slight advantage, but the mid pole makes it much easier to fix a sail that has fouled (you can crawl/slide out to the end of your bow to fix it, you can't on an end pole system unless you are a contortionist).
I personally use a Capricorn Aluminum ring, mid pole system. It cost me about $250 2 years ago, but has gone up to around $450. Many people LOVE the SNU system (
