Reefing with a sliding gooseneck

Pinning the gooseneck will result in *poorer* sail shape, and will more quickly distort a non-laminate sail material (probably also a laminate, but I don't have experience with those to say with certainty.

Simpler reefing, lower c of e, no jacklines, better sail shape.

A sliding gooseneck with an end stop has one additional step when reefing - tensioning the downhaul. But this is simpler than attempting to tension the luff with the halyard, which with the fixed gooseneck results in working further forward and pulling down, an inherently less-stable position than being aft of the mast and pulling up. Having wrestled with both at night in lousy weather, my opinion is the slider is simpler in practice despite the additional step.

The sliding gooseneck can allow a lower c of e; that was in fact part of the point of *not* switching to the fixed gooseneck.

Jacklines or not is a personal preference, not related to the gooseneck type.

And I believe you have very easy access to a sailmaker to confirm my statement regarding sail shape.

I would like more of an explanation of the distribution of forces here. As I mentioned in the earlier post, I use the flexibility offered by the sliding gooseneck to raise and lower the center of effort by raising and lowering the whole sail. When the sail is raised to the top of the mast and the gooseneck is at the top of its track, I use the downhaul to tension the luff. When the gooseneck is at the bottom of its track, I use the halyard to tension the luff. (I didn't mention thatI have boom-end sheeting, which may or may not be important.)

In the one instance, the head is fixed and the gooseneck is moved; in the other, the gooseneck is fixed and the head moves. I don't see why the effect on the sail would be different. What am I missing?
