I"ve also got a Hood Seafurl system, one of the older models. It has one line that rolls up into and around the furler
as the sail is pulled out. I replaced all the bearings in the roller last year and still found it to be very difficult to furl in the sail. FINALLY, I rented "Sailing in Heavy Weather" video from Netflix and learned that putting too much tension on the jib halyard
puts great strain on the furling system, making it harder to furl in the sail and could harm the furler bearings in the process.
I immediately slackened the jib halyard
(I did have it set really tight) a little and found the roller furler
now finally functions the way it should -- nice and easily. And the sail still seems to be tight enough to sail well without any wrinkles in the sail. I simply had the jib halyard set too tight. I could have destroyed my furler or ever broken the forestay had I not seen that movie
