Making a 505 mast (Proctor D, older generation epoxy Rondar with P&B sails – loose foot, pole launcher, spin launcher)
Well, it is something that you hope never to have to do, but chances are that while we remain with aluminium masts, we will all have to build a new one for our 505 at some point.
The short story here is that if you are happy with your current rig, then document it NOW. Thoroughly. Use the deck band as your datum and understand all halyard and control layouts. There are SIXTY FOUR holes likely required in your new virgin tube, so get documenting NOW!
