Hi. First, when furling
, always keep furling
until you've got a couple of wraps of the jib sheets
around the sail, helps keep it from unfurling during storms. If you've got a named storm coming, take the sail off and store it below.
Kinked extrusions are not good, but they may still work
. Worst part may be putting the sail in the track/taking it down. If it still works you may be able to use the bent parts
. Be careful - if they screw up it will,of course, be at the worst possible time. Ideally replace them.
Yes, there is a stay throughout your furling system.
To replace the extrusions you have to take everything apart. Since this involves disconnecting the stay, don't let the mast
fall down. Depending on your comfort level with this type of operation, you may want to hire a pro.
The sail loft probably does not need to know the make of the gear
, just the size of the slot they have to put the sail into.
Hope this helps.
