Help with self steering system

The unit in question was found aboard my boat when I purchased it.
It has no identifying marks, brand name or logo, model designation, serial numbers. Nothing whatsoever.

I want to locate the fitting instructions to ascertain what else is needed and how to assemble and operate it.

I have enclosed some photos and a photo of my boat's transom. I am assuming the fittings at each lower corner are part of the set-up or though I may be wrong.

Any help would be appreciated.

Thanks

Re: Help with self steering system

my two bobs worth - looks like an auxiliary rudder with a tab driven from a windvane - hard to say because theres no sign of a lower mount to keep it straight - should work with your boat, size wise, looks like some gear for mounting the wind vane (and the windvane) is missing. Cant really tell from the photos but there are some tabs on the transom of the boat which may have been used to mount it. what kind of steering does the boat have - tiller, wheel/cable, wheel/hydraulic? Can you find the previous owner because somebody built that thing for that boat IMHO and they'd be the person to tell you how to set it up.

Re: Help with self steering system

If that is all you have, I would trash it. The important bits are the windvane and all the adjusting mechanisms involved. That system uses a windvane to move to trimtab which in turn moves the auxiliary rudder. It would not have much power and so the boat would need to be really well balanced on whatever point of sailing you're on, which of course one should be trying to achieve anyway, but is often quite difficult when beating or in stronger breezes and a seaway pushing the boat about. Google "Windvanes" and there are any number of designs, my preference being for pendulum types like Aries,Monitor,and Fleming. Then check eBay, I bought a good Monitor there quite reasonably and I took me across the Atlantic.

Thanks Guys,

I checked out the manual and yes, there is heaps missing so I will take the earlier reader's reply and trash it.

Great to find out so quickly!

Thanks again,

Steve

Re: Help with self steering system

It's a Navik, and it is a long pendulum rudder, never seen a picture before, probably rare.

Don't trash, offer for sale or trade it in!

Yeah Sven,

Haven't trashed it yet. Perhaps a reader of this thread may need a spare!

Re: Help with self steering system

Navik. Very good wind pilots. Stick to yours. No longer made but quite repairable.
