That is not the design of a rudder of a boat that I would go around the world in. The torque to the lower part of the rudder is through torqued wood. For reliability, I prefer it to be done through a metal torque stock rod all the way down to the lower pivot, then capture the wood with a few side flat metal plates on either side of the wood. with the metal plates anchored/welded on the stock rod.. My experience with marine ply is that it does not last very long. Keep a good eye on that rudder as it is not a balanced rudder and takes an great effort to turn it. Careful when going downwind, though it is a full keel boat which is forgiving when going downwind. All the best.
Hi @carmelpule8493. thanks for sharing your insights! We really appreciate your detailed feedback about rudder design, especially regarding the torque transmission and use of marine plywood. Your experience with metal torque rods and flat plates sounds like a solid method for added reliability, especially for long journeys like circumnavigation. As for our design, we chose this approach because we stuck with the original pattern of this sailboat’s rudder design. However, we’re definitely taking your advice into consideration, especially the point about the longevity of marine ply and the extra effort needed to turn a non-balanced rudder. We’ll also keep a close eye on the rudder performance, particularly when sailing downwind. Thanks again for your thoughts, and we’d love to hear any further advice you have! All the best, Onur, Roby and little Luna 😘
@@SailingLaBoheme04 I come from a traditional boat building family and that goes back to 1709, when the first Pule' came to the island of Malta from Sicily, Your initial photograph showing your family, seems to depict one familiar street at Valletta, Malta, Since you are circumnavigating, safety is of prime importance, In your video, it was so clear to me, that the rudder was modified at the leading edge, where at 5:53 it was described as, "To improve the design, they created a modification in the first layer of the plywood that would allow the easily removal of the propeller without taking off the rudder. " Not first layer but the leading edge, It is obvious at 13:20 that the leading edge of the rudder was cut off, removed, resulting in being curved inwards so when the rudder is turned in either direction "the hollow" in the leading edge would permit the propeller to slide off the tapered shaft, and the shaft withdrawn. This was convenient, but it created a weaker TORQUE transmission than the old rudder, where the leading edge was kept full along the pivoting stock and the torque transmitted through the full leading edge. In the new one, the TORQUE is transmitted through a smaller bulk of wood close to the upper steel capture on the rudder stock. I do not like this at all! For the convenience of an activity that takes place once every few years, that modification weakened your rudder for continuous sailing! I personally do not believe that was good advice, for a small family boat, which is meant to sail long distances. Note. If that was my rudder, I would still have retained and put back the full leading edge to transmit the torque by arranging for it to be sandwiched with flat plates , two at the the top and two at the bottom. Two vertical flat plates to sandwich the three edges of the removable leading edge would add to the torque strength of your new rudder. Two larger Stainless steel flat plates sandwiching the leading edge would also have " retained the Torque effect" This is not a racing boat, and speed would not have been affected. There is little advice I can give you. Your boat is a good sturdy keel solid boat if well kept, As stainless steel shows fatigue, check your rigging, stay plates and adjusters, if they are 10 years old I would change them. Two masts will balance your boat and there is less strain on the rigging. If it has external ballast check the holding bolts. Happy sailing.
@@carmelpule8493 Thank you so much for your detailed and insightful comment! We truly appreciate the advice, especially coming from someone with such deep experience in traditional boat building. Your observations about the rudder and torque transmission are really valuable, and it’s something we will definitely take into consideration. We understand your concerns about the leading edge and the modifications. It’s always a balance between making things convenient and maintaining structural integrity, and your point about the torque transmission weakening is something we hadn’t fully considered before. Your suggestions regarding the stainless steel plates and reinforcing the rudder make a lot of sense, especially for long-term durability on a circumnavigation. We’ll also be sure to check the rigging and adjusters based on your advice. Again, thank you for taking the time to share your expertise. It’s comments like yours that help us learn and improve. Happy sailing to you too!
Wonderful result!well done !!!
Yeah !!!! It was not easy, but now we have a brand new rudder 🙌🏻
