Hi stringy and augaug,
I am glad to listen to the words of expert kayakers and sailors like you: your words reassure me
Yes stringy, I am an owner of the last Hobie Oasis model: I, usually, solo sail Oasis with standard sail (I replaced standard mast with a reinforced and lighter carbon mast, added furling system and polyethylene outtriggers) and another sail added on the bow. I am using a windsurf centerboard into the forward drive-well, too: thanks for your centerboard advice by pm.
Now, my next purpose is fitting an emergency telescopic oar at left side of the stern, as second emergency auxiliary rudder. Probably, this is excessive for the most, but I like this idea.
The reason is the following:
in the topicview you have linked, titled "Emergency Steering" (such as in another topic titled "Motor sailing the Tandem Island"), you can see that all good ideas realized by tonystott or proposed by tomray solve only the case of internal steering control line breaking (if I understand well).
Tonystott has realized a good external steering line, dogslife too.
Tomray thought is another good solution: "(...) just a tab sticking out one side of the rudder and a long stick attached to it (...)".
However, these good ideas don't solve (I believe) the case of rudder PIN breaking.
My simple idea should solve this problem, too: rudder PIN breaking and/or internal steering line breaking.
This is the reason for which I like title this topic "second emergency auxiliary rudder" and not "What would you do in an emergency?", such as proposed by sunday: I am not interested to use a hand, an arm or a paddle as a rudder, such as all expert kayakers do, neither I am interested to solve only a steering line breaking problem.
I am interested to solve both problems by one simple comfortable solution.
I like receive advice about a good mounting system of my idea, please.
