New kind of emergency rudder

I don't think I've mentioned it before here, but I love to invent things. I'm working on something new that I think no one has done before. I must make sure to NOT go into any details on a public forum, so let me provide some information which reveals nothing of the design or anything.
  • This would be an emergency rudder that can go easily from one boat to another.
  • It would not need to be permanently mounted.
  • It would not need permanently-attached mounting brackets.
  • It would be bought for less than $400, stored onboard, and easily used when needed.
  • It would be very compact for storage.
  • It would have sufficient force to overcome the effect of your normal rudder, if that was stuck to one side.
Would there be a strong need for this product?

Regards

Great New Old Idea

See http://www.selfsteer.com/products/sos/flyer.php . Go for it, however!

I would like to hear from anyone who has ever mounted the SOS rudder at sea. What kind of experience did you have?

Send a message via Yahoo to gonesail
looks like the scanmar rudder costs over $2000.

I'd be interested in an inexpensive emergency rudder of the type you describe, if it really worked.

I know we're supposed to be able to control the boat after the loss of a rudder with juy rigged rudders, drogues, sail trim, etc, but I've never actually had to do it. It's hard to simulate this problem, unless you have a removable rudder. You can let the wheel or tiller free but the rudder is still moving around creating forces.

I read a lot about how sailors have jury rigged all kinds of things with spin poles, floorboards, etc, and every story is about how great they did, never read a story where someone failed at it. Has anyone here actually done this for any length of time, and any lessons you care to pass along?

Anyway, please keep letting me know whether I should pursue it or not. I'm looking for feedback.

All offshore raceboats are required to have functional emergency rudder. You could use that as apotential market.

Bene...I think that, if you could deliver on all the claims made in your original post, you'd have a serious sales success on your hands. I, for one, would purchase if your e-rudder indeed did everything you state.
In fact, I'll volunteer to be your test-mule. Send a demo to me in NZ, and I'll trial it, and report back, on our trip to Fiji.

Thanks Meridian, I may take you up on that. When is your Fiji trip? I have to make the prototype and do initial testing first, then tweak the design. Last night was spent determining a way to make the forces reasonable, so people can use it for days on end if needed.

I wouldn't want to try it without davits or without a walk-thru transom. On mine, getting the top two brackets attached isn't too hard in flat seas, but getting the bottom two bolted on is a bit of a trick. I don't even want to think about having to do that in heavy seas without steerage. It would be a major effort.

I'm doing patent searches now. So far so good. If all goes well, prototyping starts in a week. I'll let you know how it goes.

If you can deliver on what you've put together, I'd buy one in a minute.

Thanks bstreep. The guidance and encouragement really helps.

Besides the prototyping starting next week, I will build a very scaled-down model and complete some initial testing before Monday. I'll keep you posted.
