Our hydraulic tie bar worked flawlessly for 4,000 miles, then failed miserably. 400 miles into a 4500 mile passage
I found that I was having to true the rudders more and more often until it was happening every half hour. At that point I opened the bypass valve, fixed one rudder
amidships and sailed the next 4,000 miles on one rudder
. Upon arriving at our destination
, I put new piston seals
in the rams which improved performance immensely, for about 500 miles. Now, after 2,000 miles I am back to aligning the rudders every few hours, more often than that with a following sea.
Everyone I have talked to with a similar system has had similar problems, eventually requiring a mechanical tie bar to keep the rudders in sync. I am wondering if there is anyone out there who has not had to fit some sort of mechanical fix to their hydraulic tie bar. If you have had to go to a mechanical tie bar, what was your fix?
I am currently designing 2 mechanical fixes, one based on aluminum
bars and another on a system of pull-pull dyneema
lines and pulleys. I haven't yet decided which I will go with.
