Re: Front or back grommet to attach main halyard?
Headboards are generic hence they have to be adaptable for the different halyard arrangements on the yachts on which they might/will be used. On some yachts, the main halyard passes through a block suspended from a masthead crane on the aft side of the mast hence the working line is several inches or more from the face of the mast/sail track. To insure the lift of the halyard is as vertical as possible, one would use the aft headboard hole. On other masts, the halyard passes over a sheave within the masthead itself with the fall of the working end of the line quite close to the mast, in which case one would use the hole closer to the mast. With such a sheave arrangement, using the after-most hole will increase the angle of the halyard to the mast as the sail is raised making it more and more difficult to get a tight luff and actually hoist the sail as it approaches the top of the mast.
