I am sending out these photos of my new kickup rudder that is really a fine piece of craftsmanship and design.
Made in Isreal, I found it on the web and corresponded back and forth (20 exchanges) until a product was selected, paid for, and shipped. This design is very slick and I was able to install it for a total near $250 US.
If you need a rudder this was great. Their website is www.dotan.com.
With regard to the rudder operation, first of all you have to install rudder on the boat stern. For lifting the blade you need to operate with tiller only: to lift up tiller and instantly to pull down, to return it to the original position.
For lowering the blade you need the same moving: to lift up tiller and instantly to pull down, to return it to the original position. That's all.
No ropes or elastices etc.
