[PUP] Emergency tiller

[Truelove39 at aol.com]

Hi  Bob -
 
I  have learned that besides the many programming tweaks available in setting 
 up an AP (in our case a Simrad AP26) the rudder is very sensitive to  
hydraulic system pressure. I have the bypass set at about 125psi. Even  slightly 
more and the rudder movement is so quick that in a hard turn at speed  the AP 
cannot apply counter rudder fast enough and the turn continues. Less, and  the 
movement is too slow at idle. I think the spool valves may be worn and plan  to 
replace them next summer. The main problem, though, is that the  engine-driven 
pump is too large, even though it's the smallest available.  Too large for 
the rudder that is...
 
Regards,
 
John

stuff ain't perfect. If self steering, when I look behind at the  trail, it
looks like a drunkin sailor leavin the bar at 2 in the mornin. And,  it works
the !#%# out of the auto pilot when in use. The maintenance strakes  are
probably not the culprit, even tho Nordy did try to make everone think  they
were a benifit to the ability to get thru the water (shame on them),  more
likely it's a lack of purchase on the water due to a big beam and  short
