The more I think about it the more I'm sure you're right. It's helpful and broadminded of you to engage with such abstractions, and I thank you for it; it's sometimes hard to evaluate and critique when working alone on ideas.
A way of preserving the ability would be to reserve the 'hood' for sailing or motoring under remote manual
control (allowing the tiller line to adjust the rudder
angle at will, from the sidedeck or foredeck)
But here's a new tweak stemming from your input: should there be an occasion where it might be beneficial to be able to "help" the vane gear
from one of those locations, it would be a matter of leaving the hood
off the whipstaff, but (say the hood
was hanging aft of the tiller) hitch a length of cord to the tiller line one quarter of the way across, and (pulling it straight) hitch the other end to the line three quarters of the way across the cockpit
, passing forrard of the whipstaff.
Effectively the whipstaff would then be operating within an elongated loop, and that loop could be remotely repositioned to bias the helm
temporarily in the desired direction.
This would allow the whipstaff to steer the boat with a normal range of helm
movement, without incurring the drag of the tiller lines, but (subject to hauling a couple of feet of tiller line before it took effect) still permit
giving it the occasional 'steer' if the vane gear
was foxed by a velocity header, a lull, or some such challenge while a solo sailor was occupied somewhere other than the cockpit
