You can use a tiller pilot on a Westsail but would limit use to powering. Not a big thing as the vane is for sailing and should steer the boat if it will sail. Someone used a tiller pilot as their self steering
from the Caribbean
to halfway to Tahiti
under sail and power before it gave out. They sent it to the manufacturer for repair and the tech's were totally amazed that it had lasted anywhere near that long.
On some designs, you can attach a tiller pilot to the vane to get a very low amperage draw compass steering
system. Would not recommend using a Monitor
, especially, to steer the boat under power, however. The prop on a Westsail is quite close to the vanes rudder
and there is considerable turbulence that causes a pendulum servo rudder
to dance about. Might work on an Aries
or other aluminum
vane but the constant flexing caused by the prop turbulence could cause the Monitor's stainless steel
to work harden and break. Know that Monitor recommends not using their vane under power.
Did many thousands of miles with an Aries
which the Monitor pretty much copied and it worked a treat. If there was enough wind
to move the boat, the vane would steer. Didn't have an autopilot
and barely missed it. The only time we really could have used it was getting through the doldrums when we had to motor
for over 24 hours.
We built #163, power away kit, lived aboard and sailed her to Tahiti
. Subsequent owners took her twice to SoPac, NZ, and Australia
. She's now doing occasional dinner cruisers in Kona.
