It is my understanding that spinnakers can be designed to provide lift as well as propulsion. I presume that the lift component would have to actually be larger than the forward thrust component to actually "lift" the bows, since a propulsion vector above the CR actually induces a "depression" force on the bows. So how does one design a spinnaker (or reacher??) to actually provide this component? To my simple mind it seems it would have to have a "wing" type shape vertically as well as laterally to provide both- So a large "shoulder" would be necessary or??



TIA!
