Re: 1978 Pearson 30 - broken topping lift
Most likely its a simple repair...in a difficult location.
You need to go up and remove whatever is up there that broke. Then take the whole affair to your local rigging shop to replace. Most likely won't be too much.
Just replace the topping lift with a solid vang. I had one of these on a different boat, and they work great. Its pretty much a piston which holds the boom up AND acts as your boom vang. Its a racing device, as it gets rid of the need of a topping lift, which often interferes with the leach of the main. Its a bolt on solution, with no going aloft.
