It is simply going to be 'slow going' for most jury steering
. You simply have to accept and settled into that. On average a couple of knots made good should be your expectation.
There are many jury ways to accomplish this, many ways which have actually been used to go 1000's of miles. The loads and fatigue on 'rigid' systems (like oars, sweeps and such) are high enough that you need better than average 'engineering' otherwise they will fail after a day or several. The drogues approaches tend to be less sensitive to 'engineering' and more reliable.
Your sail plan is going to be focused on helping self-steer/self correct the boat
on the desired point of sail.
Full replacement rudder
systems (like cassettes) are the only ones which will allow you to get anywhere near 'normal' speeds back . . . . but to do so they need to be quite big and quite strong. (rather bigger and stronger than most people expect).
