The system that ab1974 mentions above is well demonstrated in the pic attached (if I can manage to attach it)! I've also used this system and found it brilliant. Bamboo poles are best as they are light and strong (and cost nothing). The system is so easy it's ridiculous and I don't know why more people don't use it. The tender is off the deck and out of the way, you're not dragging it behind the boat, you don't have the complication of trying to strap it to the stern which is a pain, and to launch you just give it a push...brilliant
