Thanks. Yes, this is kind of what I was thinking, I just wasn't sure, since I haven't seen this discussed before. It's also interesting that...
Thanks Brian for opening this old thread, here is my post copied from the other thread: As a winter project, I got the rudder and centerboard...
Hi Brian, there are several interesting discussions on this topic, the closest one is maybe this:...
Hi all, I tried to dig up one of the several interesting old threads on this topic, but the system didn't let me reply to those old threads....
I can certainly live with a little heavier rudder to err on the side of safety. So basically you recommend modifying my original layup so it would...
Hi PAR, that's great info, thanks. Can I ask what was the weight of the carbon unis? When you come up with a schedule like this, is it just...
I guess I should have done earlier, but here is a picture of a cassette-type rudder, similar to what I'd like to build. [IMG] Here is...
That's the thing, these rudders don't have rudder stock, they are basically like a dagger board that can be raised-lowered in a transom-hung...
That's good to know, thanks. About that formula: Wr = k5 * 1.1 * (0.115 * Lwl + 0.15) kg/m2 Isn't it for rudders with stainless...
Thanks I'll check how that formula compares with what I did. Maybe I wasn't clear, but all that glass and carbon are in the skin (on both...
Hi, I’d like to build a transom-hung cassette-type rudder for my boat (Santana2023R), and I’m trying to figure out the layup schedule....
Very interesting, thanks!
Thanks Erwan. I'm not a native English speaker either, so I may not have used the term correctly, but by weather helm, I meant the angle of the...
Hi Erwan, thanks for your post, it’s very interesting you brought this up, because I've been trying to come up with some numbers for the...
Thanks! Now, an interesting question about using these lifting rudder blades: Let's say I'm sailing upwind in straight line in steady...
Thanks. That's kind of my plan, too. So did you glass in the SS strap joining the gudgeons embedded between layers of fiberglass or did you...
Thanks for all your comments. Here are some pics. First the side view of the boat, then 3 versions of the rudder. On the left is what I...
If the rudder is not balanced. But I plan to balance the rudder with a forward sweep, so that about the same area of the rudder would be in front...
Some transom-hung rudders have a lip under the hull to get the rudder balanced. My question is: besides balancing the rudder, is there any...
