Re: Are Two sails better than One?
1. Yes. the jib not only adds sail area, it bends and funnels the wind in a way that also makes the mainsail a more effective windfoil when going upwind.
2. Because when the wind is at just the right angle and speed, you can carry mainsail, jib, and spinnaker without any sail blanketing the other. Wrong angle, it won't work well.
3. Good question. Hull speed is not an absolute limit. But to speed above it, an inordinate amount of energy is required, and adding more sail area may just make her harder to handle without much increase in speed. Racers may take that chance and expend that effort, most other sailors won't. And, some of the lightweight, flat-bottomed skiff-type sailboats (large and small) don't have a "hull speed", because they can rise up and plane, or at least surf.
Or even rise up and "foil". You watched the America's Cup??
