Roller furling
I assume you are looking for the roller hardware, and not just the sail? If not - ignore me.Question 1 - are you going to race? If so, You are probably better off without the roller, or with a high end unit. If not, I would unabashedly suggest CDI. The Mariner would probably take the FF2; I think the forestay is too long for the FF1.CDI's roller furlers are extremely simple, durable, and don't require cutting your headstay to install. The flexible luff is easy to deal with raising and lowering the mast, and on the trailer. They're also very reasonable priced.I have the FF4 on my boat and have been very please with it.Justin - O'day Owners' Web
