Re: Reefing Roller furling jib
I will second Jons excellent explaination
Understand that a furled jib looses it real effectiveness when brought in greater than 25%Also some furling units furl equally from top of the forestay and bottom and some keep do not. This will affect pointing ability when close hauled. As Jon stated keeping pressure on the furling line is important or you will spend time sortying out the "nest" on the drum as he explained.
Finally, on our checklist when we leave our boat for the week we put a cloth bungee cord with PLATIC ENDS around the furled head sail where the jib sheets have wrapped around it. This prevents it from unfurling. We have spent time at dock jumoping on marina mates boats when in a good blow their furled headsails come undone and rip themselves apart.
