[PUP] Emergency tiller

[John Marshall]

As Peter says, the Hynautic reservoir needs to stay pressurized. I  
assume air can get into the system if it isn't pressurized properly.  
Some of the air fill valves on the reservoir leak, so this needs to be  
checked frequently. Hynautic says to keep pressurized to 30 pounds...  
but I'm not sure what pressure drop will lead to problems. I have to  
pump mine back up at least once a month to keep it near 30.

That said, my N55 tracks pretty well in calm water (I've got a 50 foot  
waterline), but otherwise I have the same basic hull shape as your  
boat, Scott. However, quartering, following seas will induce a fair  
bit of yaw as the wave lifts one corner first and then runs diagonally  
under the boat. A properly tuned autopilot will handle it, but its not  
fun to hand steer with the seas at that angle.

A narrow, canoe-shaped stern might help with that, but you'd lose a  
heck of a lot of storage and cockpit space.
