John, I installed a below deck autopilot on my Landfall 38. I went with Fred’s suggestion of the Raymarine EV-200 sail with the Octopus 1212LAR12 linear drive. I started to write up the details on my blog but basically have been too busy and forgetful to finish the write up.

Access is through a panel in the quarter berth. This was the simplest installation option which allowed for full mobility of the linear drive. I like the location as it is away from the lazarette and protected from loose objects. The downfall is that the drive body needs to be mounted right below a cockpit scupper, so I removed the scupper and place a new one just aft of the original location. The drive is bolted to the cockpit sole using a 1/2” thick G10 support plate which extends from the drive location to beyond the new scupper. The drive piston is connected to the radial drive using an Edson radial drive rudder stop post which was milled to accept the ball joint of the drive piston rod end. I bolted the mount post to the radial using the threaded bolt holes at the location Edson designed for a forward rudder stop. While I epoxy painted the mount post, I installed it with a DMD sheet insulator and Teff-Gel to eliminate galvanic corrosion(same as aft rudder stop). The rudder indicator was mounted on a custom made bracket which was bolted and threadlocked to the radial rudder post bolts via bolt couplers. I installed the SeaTalkNG backbone connecting the autopilot, instruments, and E7D chart plotter. The p70 controller is mounted starboard of the helm. With the latest LightHouse updates, I can control the autopilot from the chart plotter at the helm. I have my wind instruments connected to the network so in principle I can sail in windvane mode. I just have not tried yet. The performance is specular. Last January I sailed offshore 30NM up the coast beating in 30kts gusts and confused seas. I was only disappointed in the performance of my foul weather gear. - Paul E. 1981 C&C 38 Landfall S/V Johanna Rose Fort Walton Beach, FL http://svjohannarose.blogspot.com/ > On May 31, 2018, at 5:12 PM, cnc-list-requ...@cnc-list.com wrote: > > From: CnC-List <cnc-list-boun...@cnc-list.com > <mailto:cnc-list-boun...@cnc-list.com><mailto:cnc-list-boun...@cnc-list.com > <mailto:cnc-list-boun...@cnc-list.com>>> On Behalf Of Frederick G Street via > CnC-List > Sent: Wednesday, May 30, 2018 7:57 PM > To: cnc-list@cnc-list.com > <mailto:cnc-list@cnc-list.com><mailto:cnc-list@cnc-list.com > <mailto:cnc-list@cnc-list.com>> > Cc: Frederick G Street <f...@postaudio.net > <mailto:f...@postaudio.net><mailto:f...@postaudio.net > <mailto:f...@postaudio.net>>> > Subject: Re: Stus-List problem Landfall38 autopilot help. > > Hi, John ? unless your LF38 is significantly different from mine, there is > absolutely no room to add a proper tiller arm.
