I struggled with my in-mast furling
system big time when I bought my Beneteau
343 6.5 years ago. It took a while to figure out how to operate it with ease. My best practices are:
- Tension the furling line as the out-haul is cranked using the cabin
to deploy the sail
- Have decent tension on the out-haul as I crank the furling line on the cabin
when furling in the sail
- Never try to do it without the control of the winches; while it can be done by hand that has led to trouble
- Release the vang and have enough slack on the main sheet to allow the boom to angle fairly freely. I actually push up on the boom before I deploy to sail to make sure it can angle up freely.
- Never let someone else do it if you can avoid it unless they are trained in the above best practices.
Keeping lines tight, the boom fairly free, and others away from the task leads to success for me.
