D2 Forward or D2 Aft?
I own a 38' boat with a carbon rig and double aft swept spreaders.
The rigging is wire, a combination of dyform and regular wire.
Backstay only. No running backstays.
D2 are continuous and terminate at the deck. I have always terminated these aft of the caps.
A new and experienced crew member believes I should be doing the opposite, terminating them forward of the caps. That this effects rig tune in important ways, even how the backstay will be able to bend the mast.
This is news to me and the rest of the crew. Indeed, the distances between the wires at the spreader tips and on the deck termination are so small, it is difficult for me to believe that it makes a real difference.
The deck termination is one solid steel piece with the Caps, D1 & D2 all terminating within about 3 inches of each other (D1 inboard, Caps & D2 outboard). It all looks equally strong so either outboard termination could hold the cap load.
The top spreader has a generic tip with 2 holes, so the cap can be directed either forward or aft.
There is no information in the owners manual about this and the boat does not have a class tuning guide.
I’d appreciate hearing comments
