Re: Roller Furler for Alberg 35
It's doubtful that there's a definite 'standard' as to how the A 35s are rigged, and one as old as this has likely been modified over the years anyway.
I don't think you want to order something like that furler without specific data from your own rig. Even trusting someone else's measurements (other than a good rigger) is high risk.
