Our sailing experience on a 1987 Catalina 34 which we named 'Eximius' which google showed as the Latin translation for 'Special' We hope that our posts will help others looking to take their boat beyond the local waters as well as provide entertaining reading. I'm a Brit, so my view of entertaining may not match yours ;) See you on the water. The Journey Starts Here Paul

Autopilot Upgrade - Mounting the p70s Control Head

Installing the Raymarine Rudder Position Sensor

- Remove the Thru Bolt which prevents the Steering Radial Drive from rotating on the Ruder Post.
- Install the new Tiller Pin Bracket on the bolt and reinsert the Bolt and secure in place.
- Mount the RPS on the new Shim.
- Align the shim so that the Pin on the RPS and the Tiller Pin are aligned and the RPS arm, Tiller Pin mount form a Parallelogram.
- Run the Connector wire from the RPS forwards over the Aft Water tank and then join the loom of wires that reach the APU.

Upgrading our Autopilot - Planning
Planning the Upgrade to our Autopilot
As covered in the previous post (Click here to view), we're upgrading our Autopilot replacing the original unit that suffers from Alzheimer's.
I ordered the major parts as a kit from Defender, added the Rudder Position Sensor kit from West Marine and drew a schematic to ensure I have everything.

Here's where I'm considering installing the EV-1 the Attitude Sensor. That bulkhead is about parallel with the Helm Pedestal, the old Autopilot ACU is below the Circled area. Would make for a easy location and out of the way if anyone ever slept in the Aft Berth.
- Rudder Position Sensor can be mounted on the underside of the Aft Locker Shelf support - Stbd side.
- Tiller Pin can be mounted on a piece of starboard screwed to the underside of the Steering Radial Drive.
- The ACU-100 can be mounted where the old ACU is currently installed on the Aft Bulkhead of the Aft Berth as shown in the pic above.
- The EV-1 can be mounted just above the new ACU-100
- The p70s Autopilot Control head can be mounted where the Garmin Echo Depth instrument is currently located,
we'll have to figure out where to move the Echo instrument. The Echo Depth Instrument can be moved to the Port Side Pedestal wing, we'll just remove the temporary cup holder that is mounted there at present.

Upgrading our Autopilot
Upgrading our Raymarine Wheel Pilot to a Raymarine Evolution EV-100 Auto pilot.
Our Autopilot has Alzheimer's - keeps losing it's memory and not sure where it's going. Time to upgrade.
After lots of research, despite wanting to have a Garmin Autopilot to match the rest of our Garmin Electronics, they just don't have one that is suitable for our size boat that would fit within our electrical power budget. So the Raymarine Evolution EV-100 it is.
The model I selected is the EV-100 Sail Wheel Pilot. From everything I have read on the subject, it's best to have a RPS (Rudder Position Sensor) attached (link here). Also, the Evolution system should be able to use the data and some commands from our NEMA 2000 network and Garmin 741xs Chartplotter.
Here's our current Helm Electronics setup. The Garmin GMI instrument on the Starboard Side of the 'Navigation Electronics Shelf' is mounted in a DIY holder. It's made from a piece of PVC piping and a piece of Starboard material.
The new Raymarine kit includes a p70s Pilot Controller. I specifically chose the p70s rather than the p70. The format of the p70s is more closely aligned to the Garmin GMI instrument, so if I match the housing of the GMI and mount the p70s where the existing Garmin Echo Depth instrument display is (on the port side of the Navigation Electronics Shelf' ) it will add a degree of order to the shelf.
We'll have to figure out where to mount the Garmin Echo, probably below the shelf.
The new Autopilot has similar modules to the old system just a more updated / improved feature set.
Just a quick note here. The manuals suck! They don't even clearly identify all of the components of the system because they include the components of several other systems. It takes a lot of reading to figure out which parts of the manual are applicable to the system I purchased.
The Evolution system has:
- ACU 100 (The Brain)
- p70s Controller
- EV-100 Attitude Heading Reference Sensor
- Evolution Wheel Drive
- RPS - Rudder Position Sensor.
From my previous experience working on Autopilots, the wiring has been an issue, particularly when the wiring was not via a Plug and Socket, such as the Power Supply, motor connection and the SeaTalkng connection to the ACU. The wires are typically far to small to fit properly inside of a screwed connection.

Memorial Day Weekend Cruise to West Palm Beach Pt. 1
HISC Memorial Day Weekend Cruise to West Palm Beach.
After spending Thursday night on Lake Boca tied up with Affection (Jeff's Boat ! ) we pulled anchor at 07:30 in order to get the 07:40 Camino Real Bridge opening while Affection motored out of Boca Inlet, his draft is just 3' ours is nearly 6' and Boca Inlet is too stressful for us.
07:43 we passed Camino Real Bridge and motored the 20 minutes to Hillsboro Blvd Bridge, then it was a long slog of 60 minutes against the current down to the Hillsboro Inlet Bridge, by the time we were ready to pass the bridge, Eximius was pretty well dressed for the Day, Sails & Sheets ready, fenders all inboard, Lines secured, ready to hoist the sails.
Just as expected, the wind was very light as we navigated carefully out of the inlet and avoided the shallow area on the North side of the Inlet and 'gonna get you' shoals on the South side of the inlet.
We turned to 045º with the intent of trying to reach the Gulf Stream under motor while the wind was so light. We did raise the sails but they pretty much just hung there. By the time we were a mile and a half off of the shore, we were feeling the Stream pushing un north. Engine given a rest and we trimmed the sails. With less than 5 knots of wind, we were barely moving through the water, just 2knots. But the Gulf Stream was dragging us North an additional 4 knots! Expecting the wind to pick up before lunch time, we stayed on course.
Soon the wind picked up to around 7 knots, and our GPS speed was 9.5knots WooHoo! The Sea was very steady and it was an easy sail. The Autopilot managed just fine once we had some speed through the water.
The only issue was that the course that I imported from Fastseas.com had some issues. Last night I had reviewed the route on fastseas.com and switched the Start and Finish over so that we could see what the return trip would be like on Monday. Totally forgot that I had switched the Start an Finished and proceeded to export the route. Once it was on a chip, we imported it on our chartplotter then set the GPS to follow the route.
Sounds ok, except that I had not remembered the switch over. So initally the chartplotter reported that we would reach our destination by noon. That was great, a bit unrealistic, but great. As we proceeded, the arrival time got later and later.
Duh!
Once I realized the problem, I simply deleted the route and set a route to arrive at Lake Worth Inlet.
All of a sudden, our late night arrival was now around 2pm.
