  1. If you have a steel gunwale surrounding the stern like I've seen on some boats, you have to cut out an area to allow for the front of the S shape where it connects to the rudder stock. This would be far more complex to have to make an inset pocket, to match the outer curve of the gunwale steel (like the initial post photo). Simply doing a C shaped tiller would have meant they would not have needed to make the pocket co clear the lower end of the S curve tiller. While there may be other reasons, I think the primary reasons are to build in a "stop" to keep the tiller from being pushed hard over far enough to hit the prop, plus a little bit of "that's the way we do it" thrown in for good measure. Why change if there is no clear advantage.
  2. As anyone who has worked steel knows, you can bend it any way you want, just apply a little heat. If you've built the boat out of steel already, the tiller is just a bit of fluff... Yes, steel springs back, but it also springs back on everything else. You just bend it over what you want, accounting for the spring back. If it's not enough, do a little more and check your work. If you can't make two bends in a rod or pipe and end up with what the customer wanted, you need to find another career.
  3. I'm assuming what you call the counter is what we call the taffrail and that's probably the simpler way to limit travel. Most power boats have stops that limit the rudder to 40 degrees off center in each direction. With the top of the S curve hitting the railing, that's your stop.
  4. I think I have an idea of why it is an S shape rather than straight up and forward. It probably does not have rudder stops to limit the travel and if it didn't have the S curve, it would require stops to prevent someone from accidentally turning 180 and the tail of the rudder hits the prop. I guess a sideways U would probably limit the rotational travel too but the rear bend sticks far aft enough that you'd strike the railing before you hit the prop. That is assuming you have a railing.
  5. There is no mechanical advantage since the mechanical advantage is from the imaginary line directly above the rudder stock to the tip of the handle. Anything aft of the rudder stock is of no advantage. I see some value for the S curve being a "rudder angle indicator" and it should act to a degree like a balanced rudder would, since some of the rudder will project forward of the rudder stock, and most of the blade will be aft of the rudder stock, would act as a indicator of where it is and what angle the rudder is currently. Still, the bottom of the S could be a J, exiting from the aft edge of the rudder collar and simplify the aft railing manufacture. I think it is the way it is primarily since it has been the way it is for a while, and they know how to make it that way, and if they changed, people would say "That looks funny, why did you do it that way, and not the S curve way?"
  6. Why is the tiller on a canal boat shaped like an S, where the tiller attaches to a collar at the top of the rudder stock, with the tiller arm going off the front, then bent upwards and backward to go over the pivot point of the rudder stock, then back forward? I see canal boats that have a pocket in the back railing to accommodate the forward part of the tiller arm at the base of the tiller, when it seems that if the whole collar and attachment point exited to the rear and then had two 90 degree turns, the same effect could be done, without having a tiller pocket. Is it done to get the tiller out of the way of a possible collision from astern?
  7. Canaline uses a Korean farm equipment engine brand called Kioti, with the engines built by Daedong. It is a common practice to leave off balancer shafts on industrial engines that are normally included on tractors. Why? I think they say if it is an industrial engine, mounted to a trailer or concrete pad, who cares if it shakes. Some manufacturers also lighten the flywheel on industrial engines, and on fewer cylinders, that makes it rougher power. I don't agree since vibration is the enemy of longevity, and more vibration caused by an engine has to be isolated better or the whole boat will become a sounding board for the vibrations. It appears that Sole uses a combination of Mitsubishi and Kubota engine blocks and are marinized for boat use.
