How/When to hoist sail.

[chrondi]

I think that the following item is missing from the above list of the mainsail hoisting procedure, between nos. 11 and 12:
Tighten the boom-vang.
That's how we allow the mainsail sheet to control only the swing of the boom.
The preventer needs to be fitted only if we bear away beyond the broad reaching point of sailing.

If you're talking about the list I posted...this is moot... since I don't have a boom vang yet.

Yes, there are exceptions and one I frequently use is blanketing a foresail with another to raise and lower. This is one of the great advantages of a two-track headstay foil and I do this on every point of sail. It's a great way to swap out a genoa for a working jib, for instance: Raise the jib in the shadow of the genoa, tack and lower the genoa in the shadow of the jib. Your larger question is answered by: he sail you're raising or lowering has to be unloaded. Roller furling, as previously mentioned, is a bit different and a jib may be rolled up on any point of sail. A main, however, has to be unloaded to roll into the mast. If it's boom roller furling, it is more forgiving but not by much. Hope that helps!
Cheers!
