Solent Stay

[benz]

You only need a bar-tight luff on the jib when pointing as high as possible. In that scenario, you'd likely be using the jib on the furler, rather than a bigger foresail on a Solent. If the wind was light enough that the bigger foresail was appropriate for pointing, then the luff wouldn't sag that much, due to less pressure on it. When off the wind a little, the advantages of the larger sails would be worth the trouble, I think.
You should really freak out the Sailnet people by suggesting the addition of a bowsprit, just for fun.
