A FRAME without a doubt. As I posted earlier, I pirated the Aviator James version and made a couple of small tweeks to benefit my needs. Raising and lower the mast is now a simple single handed task I no longer fret over. Originally I built a gin pole rig and it too worked well with the exception of control over the mast position relative to the center line of the boat. Adding side stabilizers to the gin pole rig did help but are a task to get attachment at the exact point on either side as well as equal tension. Consider these to be an aid only and not a solution, unless they are perfect.
Every year I get asked if I need any help once the frame is in place and ready to raise or lower the mast. No thanks, I got it and they stand back and watch. MY set up, OK AJ's set up has now been replicated a few more times in the yard.
Off to the boat,
Curt
