Thanks, guys! It made sense from a physics viewpoint, but I couldn't remember from the other boats I had/sailed. I tried to find photos of masthead rigs under sail but couldn't find any that where definitive.
Does it make sense that the boat will point higher with the head sail higher? It seemed obvious to me that the slot was working better, but that judgment was subjective.
I will increase the pennant length after I check the other headsails (working Jib and Blooper).
There are two types of fools...
One says this is old, and therefore good..
The other says this is new, and therefore better...
