Norvane Emergency Rudder System

- Building and testing an emergency rudder for a Norvane windvane on the 28-foot Pearson Triton sailboat, Atom. The rudder sleeve size is double the area (10" x 34") of the original Norvane servo rudder, which is 7" x 24". To balance the rudder I kept 20% of surface area forward of the axis.

Very well done! thats the kind of video's I'm always looking for. So many just show them sailing. You did a great job.
Thats pretty clever. Well done.
another awesome and informative video! Thanks for sharing!
Genius
Jim thats brilliant . Do you think this could be done with a pacific or south atlantic windvane?
I believe the makers of Windpilot Pacific and Monitor have a factory made option for emergency steering. Not sure about fitting one like mine to the South Atlantic but if it is similar design and operation to the others then it could be done.
James..I really enjoy your videos, very instructive and informative. The outboard motor integration and subtle aperture for the leg, kept the lines of the boat looking beautiful. However, the wind vane and secondary rudder engineered solution, have rendered the stern into a confused scaffolding site, that has ruined the look of the boat IMO. It's a case of engineering overtaking aesthetics. Clearly I'm a believer in elegant engineering and not everyone thinks like that, but the rest of the boat demonstrates that design philosophy...except the stern😩
Thanks for your comment. It's true there is no beauty in a windvane - until you cross an ocean and don't have to hand-steer or carry several tillerpilots that only work well in light conditions, breakdown frequently, and have significant electric demands. Windvanes start to look a lot better after you use one long distance. A less bulky design such as the Cape Horn Integrated model looks better but occupies the lazarette so no outboard well can be fitted with them. The aesthetics in this case is really about what you get used to seeing and what features you appreciate most. After all, most sailors on slightly bigger boats have gotten used to ugly inflatable dinghies on stern davits, which are even worse on the eye.and take valuable space the windvane could occupy. The cascade of compromises begins there and then they must choose an energy hungry below deck autopilot and more solar panels to feed it. When that is not enough they add an unsightly wind generator that adds shadows to the solar panels, so maybe they have to run the engine or add a generator. With extra generating capacity, why not add a watermaker. And so it goes. As for the emergency rudder contraption, yes it's hideous to look at but I'm sure that's not a factor at all because it stays in a locker until the steering system fails. After it gets you into port it goes back to its locker.
This is incredibly helpful video, hey do you think my new Norvane aux rudder will help my Halman 20 point a little higher into the wind? Its got a full keel hull with keel hung rudder and Im thinking with your aux rudder sleeve mod it would allow my boat to sail upwind better, especially since its hung much further astern than main rudder…welp i cant wait to try after the i install
What I set up is an emergency rudder for steering the boat when the main rudder fails. Despite the emergency Norvane rudder being further aft it does not improve steering over the main ridder because it is much smaller. I'm not sure about your application.
Ok Thanks!
I figure I'm missing something but I thought I'd ask, is there an easy way to put the secondary rudder on over the primary rudder? You know, without going for a swim?
+SavvySalt Yes I should have mentioned or shown how the Norvane servo rudder swings all the way up to starboard anytime you want it out of the water. When it's up is when I slide the emergency rudder sleeve over it.
James, in all of your videos and blogs online you show experience with windvane steering. Did you ever experiment with sheet to tiller? if not why?
I very much enjoy your content :)
+Tom A The first couple years I owned my boat I used various sheet to tiller self-steering arrangements that worked more or less for short periods of time. Beating with a line from the mainsheet to tiller opposite a piece of surgical tubing worked fairly well but most of my passages have been downwind and nothing worked well. It's a good skill to practice but not a good system for singlehanding long distances.
yes:) smart
