Moonduster 312 #7 Posted June 25, 2019 There are three components to an auto pilot: Drive Control head Instrument interface So some questions: What instrument system do you have? Do you want to be able to drive to AWA and/or TWA? Is your steering tiller or wheel? Who will do the installation? Is your boat 12V or 24V? Do you plan to race, cruise and/or deliver under auto pilot? Do you expect the pilot to be able to drive off the wind with a kite up? Share this post Link to post Share on other sites

jack_sparrow 7,490 #9 Posted June 25, 2019 While light and only 35' cockpit layout probably precludes having a Tiller AP for all but deliveries, but going to be more expensive with a below deck drive. If already have B&G you might as well follow suit using their Course Computer (that uses TWA or AWA) and also enjoy MFD AP control down below if you have one. Only choice left then is either electric or hydraulic drive where existing power generation/storage setup might help dictate that choice. Share this post Link to post Share on other sites
Zonker 2,455 #10 Posted June 25, 2019 1) Pelagic (now sold by Scanmar). Pretty robust drive units (industrial linear actuator not that crap that Raymarine sells and calls waterproof). Cheap ($875 US). Spare drive units are dirt cheap at $149 (you have to remove the bracket and electrical plug off old one so not a complete plug and play replacement)https://www.scanmarinternational.com/pelagic-autopilot Lots of folks in the Singlehanded Transpac used them. No affiliation, just a satisfied early customer . Just noticed 24V (who has a 24V system on a 35' boat? Queenslanders sigh). Ok you'll need a 24->12V converter too. 2) The expensive, power hungry because hydraulics (but probably a bit more powerful) solution is this: http://minitransat650.com/leov/html/autopilots.html 3) We sailed around the world with a Raymarine 4000 GP and a few drives. The rate gyro was great and kept the boat sailing along with a kite quite happily (but it was a catamaran so not at all likely to broach). The Raymarine drives are not robust and let water in, and eventually the motor goes. I bought a Pelagic drive that the Raymarine computer was happy to actuate and had a good solution. 4) it used to be the Single handed transpac people would have a bunch of the cheaper Raymarine tiller pilots and just plug another one in when one died but a 1D35 is a bit too much boat for the Raymarine 2000/Simrad TP32. And with the Pelagic drives, they are nowhere near as good for similar money. Weak points of all these drives seem to be: - tiller connection (I snapped pins every 5K miles). Just have a 2nd pin already epoxied in place an inch further aft and keep sailing when pin #1 snaps. You can use 1/4" s.s. machine screws because the diameter is about the same and unscrew when it snaps. The threads make it less fatigue resistant but because it's through bolted through the tiller, much quicker to replace - electrical plugs for option 3. Stock units are very non corrosion resistant. Had to replace lots of wire where salt water kept wicking into the wires from the connector. Pelagic's connectors are better. Of course option 2 have no electric connectors so a win there Share this post Link to post Share on other sites

Zonker 2,455 #17 Posted June 25, 2019 Is the rudder shaft exposed below deck? i.e. stuffing box / seal at lower bearing, not an enclosed rudder tube coming up to deck. Fancy dropping the rudder to cut a keyway in the shaft for a tiller arm (I'm not sure I'd trust a clamp-on quadrant without a keyway)?

Zonker 2,455 #21 Posted June 26, 2019 Older style boats (not the 1D35) certainly had full depth rudder tubes. Not unheard of. How is the helm load? That's really the defining factor if a tiller style unit will produce enough thrust (and fast enough) to be useful. I don't agree that it has to be an underdeck model, given my own experience and those of a lot of single handed boats of similar size in the Singlehanded Transpac. https://www.sfbaysss.org/main/resources/ Good discussion on Autopilots by the guy who developed the Pelagic: https://www.sfbaysss.org/resource/doc/SSS_Autopilot_011314.pdf Share this post Link to post Share on other sites

Zonk this is a boat specific thread. A OD 6,500 lb, 35 footer, slick, quick and nimble rudder to boot so a tiller unit will handle it a heartbeat.

Zonker 2,455 #23 Posted June 26, 2019 I wasn't really thinking about cockpit layout too much. These tiller pilots all attach ~18" forward of the rudder shaft. For single or double handed racing, all the controls seem to be well forward of the tiller except the traveler. Might have to have a support or extender at the cockpit side wall but certainly it doesn't seem like it would be in the way. What am I missing too? Share this post Link to post Share on other sites

When I had a smaller boat and a tiller pilot I considered putting the drive inside somewhere....under the winches perhaps. Then much like a windvane-to-tiller arrangement use a line and blocks to connect the tiller. That drive unit out in the cockpit is a disaster: water intrusion, tripping, line tangling, wires, etc. Requires super low friction blocks, BTW. But I bought a huge boat that painlessly fits an underdeck and quadrant. Hacking up that 1D35 hull to fit a quadrant seems like overkill. Share this post Link to post Share on other sites

It's because (a) monohulls heel (b) not all designers have the ability to get both rudder balance and rig balance correct on every boat in every sailing condition. When a monohull heels a lot (think a reach on a windy day) the center of effort of the sail plan is way over to leeward somewhere. This produces a turning moment which increases weather helm. And wider sterns with assymetric waterplanes also produce turning moments. Modern deep racing spade rudders with really good and accurate foil sections reduce helm loads, but not for all conditions. Some boats are more easily balanced by trimming main and jib in different ways to reduce weather helm and thus the helm load. Guessing the "lead" between static CLR and CE is actually hard unless you are duplicating a very similar hull and rig. Share this post Link to post Share on other sites
eliboat 249 #38 Posted July 18, 2019 Don’t forget, that as water is 800 times more dense than air, a larger than 1% shift in CLE can cause a significant imbalance that could result in either weather or lee helm. If this is the case, messing with the sailplan will do little to remedy the situation. Share this post Link to post Share on other sites

However there is a discernible inertia effect. It indeed moves without much friction, but your motion must spin the shaft, pulleys, and clutch mechanism. I think most drivers would opt to disconnect the actuator from the rudder arm when racing. A trivial operation if the area is accessible. The inertia effect is present with all wheel systems. Especially if the wheel is s/s rather than carbon. The weight of the wheel must be accelerated regardless of frictional resistance. That requires work.

DanimalNZ 7 #41 Posted August 17, 2019 thanks, interesting - so i have a tiller - and therefore only use a tiller arm connected to the linear drive unit, i would not have the issues which flow from any pulleys (which I imagine would account for most of any resistance)? thus, being of simpler config, its a good bet that i wouldnt notice the inertial effect?

The pulleys I mentioned are the toothed belt connection inside the Type 1 unit. Very low resistance but spinning the mechanism back and forth take some small effort. The drive would be connected to a short tiller arm under-deck (300mm?). The connection is a simple ball joint slipped over a pin with a spring clip retainer. Trivial to remove and most racers do so. Casual sailors probably not. The Type 1 could weaponize the real tiller as it swings across the cockpit. One quickly learns to not reach for the beer can thru the wheel lest a sudden turn break a wrist, or worse spill the beer. Share this post Link to post Share on other sites

Jeff F 7 #45 Posted August 28, 2019 I put a Raymarine EV 200 AP with a type 1 linear drive in my Mount Gay 30 this year. Cut the stern tube and put a gaitor seal in, and had the shaft keyed to mount the 300 mm tiller. I was prepared for the drag of the drive unit when hand steering, but what I hadn't considered was the restriction on rudder movement. We had to put stops in to limit rudder rotation to about 35 degrees off center to protect the drive unit. I have to remember that I can't spin the boat. I'm very happy with the performance. But if I were doing it again I'd probably try a robust tiller mounted unit like the EV100. Share this post Link to post Share on other sites

Yes, that is another reason racers make it easy to disconnect the drive from the A/P tiller arm: rudder limits. Worth adding an access hole to accomplish it quickly. My travel limiter, to protect the drive, is not the recommended fixed blocking. It is a strop of spectra from the quadrant (or could be A/P tiller) to a padeye about a meter forward. It too disconnects in seconds for racing. Share this post Link to post Share on other sites

Then, an underdeck drive that I control with PyPilot running on a RPi or Beaglebone Black, something like that. The underdeck control computer gives me options to try various technologies, perhaps a machine learning algorithm that learns to just emulate what I do. My boat had an autopilot that used an Octopus drive, and the person who created that autopilot is a huge fan of the Octopus drives. I never used the previous autopilot due to very many instrument and connector issues. The autopilot I use now is the one solo sailor recommends in his book "Singlehanded Sailing" (that is at my right elbow at this moment): a rope with shock cord on each end. I wrap the rope a turn around the tiller, and it keeps the tiller in more or less the same place. Works pretty darn well in practice, but of course won't allow me to go to sleep or leave the cockpit for long. Share this post Link to post Share on other sites
Zonker 2,455 #67 Posted June 18, 2020 Pypilot was written by Sean D'Epagnier. I met him in South Africa. He's a character and is one of the developers of OpenCPN. Clever guy. 1 Share this post Link to post Share on other sites

I was intimidated by the octopus and the solenoid and the lack of a manual, but laid out on the bench with a 12v power supply, was able to figure it all out. A little bit of tape and voila, all wired up on the boat. 1 Share this post Link to post Share on other sites
carcrash 361 #69 Posted June 19, 2020 Razr, When I called Octopus, they suggesting doing exactly what you did. 1 Share this post Link to post Share on other sites
DanimalNZ 7 #70 Posted June 20, 2020 Carcrash - think I'm gonna run a palegic under deck ram with pypilot (using a pi zero W to start with, but might grunt this up with a pi-4), and see how that goes. Would be interested to see how your config goes. 1 Share this post Link to post Share on other sites

The Dark Knight 683 #72 Posted June 21, 2020 This would be a perfect SH AP setup for a 1D35 or similar BOBO seems happy with it. 1 Share this post Link to post Share on other sites
enargee 0 #73 Posted June 30, 2020 Dark Knight, I really really like this setup and had something much like this envisioned in my head for my Mt Gay 30. Am I correct to assume that setup is a Lecomble and Schmidt hydraulic drive unit? Which model did you go with for what length yacht? What autopilot computer / instruments is it coupled with? Any computer calibration issues given that it's essentially a "reverse" drive and located much closer to the rudder stock? I assume this is essentially an adapted below deck system? Why didn't you go with a pelagic or similar system with the same install? Do you want me to ask some more questions Share this post Link to post Share on other sites

Do you want me to ask some more questions I have not done this as I am boatless, I am curious about the setup just in case I eventually end up with a boat with a tiller. FYI the setup in the photos is on an Elliott 10.5 Motorboat 2 that has been successfully raced 2h in NZ. There is a Young 11 with a similar setup that was done for solo racing, but the actual unit is hidden. Don't know what the drive unit is, but the AP is Raymarine. This boat has dual course computers for redundancy Are you the new owner of Prion? Share this post Link to post Share on other sites
enargee 0 #75 Posted July 1, 2020 Well thanks for sharing those pics anyhow, guess I need to find somebody locally who has a similar setup to find out more. RE Prion - yes, 1 of. So much for anonymity on the internet, guess I need to abandon my plans for trolling with this user account... Share this post Link to post Share on other sites

Bruno 113 #79 Posted July 21, 2020 I thought the 18" tiller length was required for most til,er drives? 12" is ok for hydraulic? Share this post Link to post Share on other sites
SSolo 149 #80 Posted July 21, 2020 have spent 1o0000's of mile short handed / solo ; IMHO the all in one tiller pilots are not even damp proof and hence why you need quiver of them. Save your money up and install a separate ram and pilot computer. IMHO it is all in setting up and calibrating carefully ; most people switch on and let the brains do it - dont! Spend the time calibrating instruments, rudder feedback, log, wind angle etc - you will benefit looking at pilot computers Raymarine - on open 30 mono and 40 offshore tri ; didnt like them, were ok in compass mode and poor in wind modes, could only do only apparent wind angle. this may have changed set up i found awkward as IMHO it was set up as 'plug n play' rather than setting up to personal needs/preference, but is you want low cost basic then they fit the bill B&G 5000 have had/have them on both on the Open 50 mono and Seacart 30 tri great, takes time setting up and calibrating everything carefully including the 'what to do, when' eg bare away or round up in a gust. But is much easier with B&G web interface (NB the simrad computer is 'cut down' B&G unit) looking at Rams the raymarine linear drive ram is good, but use another computer to drive it, or better still get a Hypro ram (they make the rams for B&G, Simrad etc) Currently i have the octopus RS drive ram on the Seacart with ram below deck and a long 'cable' to tiller so motor etc is secure below deck; it is easily disconnected if required i really rate the octopus drive/ram - very simple idea and very effective 1 Share this post Link to post Share on other sites
