Help! I have the ring to which the forestay and jib stay attach fastened to the front of the backstay crane. I notice the the ring tends to rotate so that it is at 90 degrees to the hull centreline and that then tends to make the boom sit out one side, favouring one tack over the other. What’s the answer? Soak the dynema between mast head and ring in superglue to make it rigid??

Hi Simon, I put a DF65 A+ rig together recently for a trimaran, which I have now sold. However the forestay attachments is as follows.

Tie a line to the front of the crane and tie the ring to that and then attach the jib / forestay to that, with a bowsie for adjustment. The jib topping lift ties directly to the above hole in the crane.

Managed to find a picture, which should explain it all.

Good luck

Richard

Thank you Richard. My topping lift is attached to the ring. I think I might have seen it attached to the front hole of the crane somewhere as you have have done so I backed the tension off the backstay and two things happened, the boom still pivoted away from the centreline but the bottom of the boom now catches on the deck furniture  so, for me at least I’m a bit dubious about the topping lift position, but I may try it anyway, 

Thanks again 

Simon

Hi again Simon,  I also found this part of the A+ rig tricky. There is not much room at the top for the line and bowsies and the shape of the jib foot limits the amount of mast rake. I wanted maximum mast rake and also found that the boom hits the deck. Maybe worth looking at the mast rake and the location of the swivel line along the boom.  Looks like they crated the A+ rig simply by adding area to the jib as much as possible instead of a taller overall rig.

As I mentioned, I was using the rig on the DF hull with floats and cross beams added. My solution for obtaining the mast rake I wanted was to make a new jib with a more usual kicked up boom. See pic. Think I prefer the standard A rig !

The topping lift position does work; it may still pivot away but no where near as much as when  it is moved away from the mast.

Hi Richard,

I’ve relocated the topping lift upper attachment to the front of the crane so we’ll see what happens!

Thanks

Simon
