Are you planning on having the
engine running whilst doing this? If not and you go into irons the
boat will eventually stop and fall back, one way or the other. I don't see how the tiller pilot can control the
boat if its not moving forward with the
sails are flapping whilst you adjust them.
With the
engine running slowly, a couple of dabs of the 10+ will put you in irons but the engine will provide the drive to keep the boat going on a steady course whilst you adjust or reef the
sails.
There are some home made remotes which have been discussed on here before, perhaps 4 years ago. Sailorchic34 built one.
