A Simple Proa Rudder - Waimea Proa E5

One of the first thing you learn about proas is that it's hard to design a rudder for them. Well, here is my design. It's inspired by the way a steering oar is used on the marshall island (and others). An oar is tied to a line, the other end attached amidships. The oar is then held to the lee side of the main hull.
In my version, I've got another line at the top and a cleat to hold it in place, and have a tiller and extention on the oar so that it may operated single handed from the platform - while trimming the sheet and providing righting moment!

Good to see you back!

have been very busy have a few more videos in the pipeline!

Thanks for the update!

Thanks for the clear explaination

Good solution. Appropriate level of tech/complexity for a vessel that only needs a rudder under a few specific circumstances.

@dominictarrsailing 11 месяцев назад

and is also easy to quickly remove rudder completely!

Fab, it's been fascinating watching all the sailing experiments. Also love seeing "home". I grew up in Whenuapai so it's great to see where I've capsized. 😂

@dominictarrsailing 11 месяцев назад

Yeah im getting pretty happy with everything now... nearly a year! What did you sail?

Simple approach is my favorite. I’ve seen some of the islanders use the rudder in what looks to be backwards, as in the tiller faces aft and is front of the operator. Also is held in place by hydrodynamic force. Boat looks good natural style.

@dominictarrsailing 11 месяцев назад

Yeah that's the Satawal island style!. Also in Sri Lanka they have similar, but the handle comes sideways at 45 degrees (half way to the viking style). So the helmsman sits behind it an pulls to turn to weather.

Thanks Dominic. It's always great to see another video from you. You're one of my favorite content creators on RU-vid! I'm a bit surprised to see you go for the rudder, you looked awesome and smooth in your last proa video. By contrast, everything in this vid seems so much more busy, clumsy, and awkward. Can you not control direction well enough with weight-, sail-, and mast-shifting?

@dominictarrsailing 11 месяцев назад

No can balance very well with all those thing, but the problem is none of that is a fast response. A big gust of wind causes sudden strong weather helm. Sail forces relate to wind speed, and water forces relate to boat speed. In a gust, wind speed increases suddenly but boat speed takes a while to increase. So I can have a burst of speed but can't keep it straight so can't hold on to that speed for long. A rudder enables you to suddenly increase water forces to balance sail force.

Oh but also, I'm not married to this rudder, it's an experiment!

@@dominictarrsailing Ah, okay, I understand now...Thanks for the explanation. Anyway, please keep the vids coming of all that you get up to, whether it's proas, fixing up your Wharram, sailing trips, or whatever. You always make interesting content - and you introduced me to the music of Disasteradio!! :)

Cool idea. It doesn't look much easier than using a steering oar, have you tried that? I liked using the typical Kiribati arrangement with forked sockets at each end and a simple oar. I was just thinking about it and a curved oar would allow you to sit further to windward, and would still use great for bearing away. And perhaps still work OK as a paddle and possibly a yuloh?

@dominictarrsailing 11 месяцев назад

well I tried an oar mounted on the end of the seat (same beam as the mast step) I found it to be quite hard work. It wasn't a great oar though, I found it washed up in a creek. it would have been a decent oar for rowing, is cupped one side. For single handed I think the oar lock needs to be reachable from the platform.

@dominictarrsailing 11 месяцев назад

on the waka hourua they have a steering oar like that, but it also has a pin so it doesn't twist, and also they put a rope around it so you don't have to take the whole force, just raise it up and down

@BalkanShipyards 11 месяцев назад

Pretty flimsy concept bro, but works well and you shunt fast!! I like it. What about adding a lump of wood on the side for it to pivot on? Anyway it works well and shunts fast!! So keep shunting brah, d Force is with you 😜

@dominictarrsailing 11 месяцев назад

The original plan was something like that, actually with a socket like an (indonesian) junkung rudder. I might still try some things there but I really like that it sits flat on the hull. It's just a steerable leeboard. And the force is with you also!!!

@dominictarrsailing 11 месяцев назад

I think I like to start off flimsy then make it stronger as necessary depending on testing

@BalkanShipyards 11 месяцев назад

@@dominictarrsailing I would like to see if adding a pivot and separating rudder from hull would reduce turbulence? Keep shunting brah, well done! By the way, I think u have to go to the doctor and tell him u got proas in your blood.....
