Rudder rubbing on hull when turning to port

   Hi Roger,
This is very helpful.   It really sounds like my clearance is just too little to start with.  I will try to take some better pictures myself and post them so it is easier to compare.  I sent you a direct message with my email address.  If you could share yours, that would be very appreciated.

As an update, I also communicated with Jefa.  Their advise was to drop the rudder, the recommend doing this anyway every three years, check bearings and in particular the Delrin trust washer.   They referred to Hanse for the recommended clearance.

PS: the 500KB limitation on pictures feels indeed a bit "out of date".  I used microsoft paint to reduce the sizes

	Hi Harald PM sent by email which will give you my address and the requested photo. High Time is 13 years old and the rudder has never been dropped. The steering is still finger light so I leave well alone. I figure if something is wearing (bearings, washer etc) it will give me fair warning before it fails completely. I do check/adjust the cables etc. regularly as their failure could be catastrophic and without any warning.

	Quick update, dropped the rudder, inserted the Delrin washer recommended by Jefa and after reassembly, checked for plumbness by seeing if there was any movement in the bottom of the rudder, underneath the end of the rudder stock, moving when the rudder was turned over from port to starboard. None was observed so things seem okay now.

	Hi, On my 385 the rudder is also rubbing against the hull. I think it is similar to your problem. Did you find a solution and did you hear from JEFA? Thanks.

	When I purchased Ruby, my Hanse 370, she had just been fitted with a brand new rudder. The clearance was almost nil at the hard to port and starboard position. The solution was to remove the spacer immediately below the tiller arm and have a few mm skimmed off. This allowed the rudder to drop down and create the necessary clearance.

	Hi Thomas Yde, Jefa suggested installing a Delrin washer, specifically either M07-169 Washer, Delrin ø88.5 × ø119 × 4.5 mm (€20.11 per piece) or M07-169-B Washer, Delrin ø88.5 × ø150 × 4.5 mm (€32.68 per piece). Since this was faster and easier, my yard instead purchased a sheet of Delrin and machined one themselves. You do need to drop the rudder to install it, but this was actually quite straightforward. After installation, we could not detect any meaningful asymmetry. There is likely some minor asymmetry in the hull or shaft, but it is so small that it does not really matter and only becomes noticeable when the rudder has no clearance. I hope this helps.
