I recently bought a Passport 47, and it’s in really good shape but a bit of the running rigging is tired. I need to replace the mainsheet and I have questions on the running backstays. First off, what type of line should I use for the mainsheet? It is just regular double braid now and the guy at the chandlery suggested Dyneema, so I am not sure what to use. Second, the boat has running backstays, do I need to use those all the time? They are made of wire and hard to handle, they tend to rub on my nice new mainsail too. Can you shed some light on this?
