Rudder Stock Self adjusting Pendulum

[Diatonic]

Can anyone help me to understand what a "Rudder Stock Self adjusting Pendulum" comprises or means? I have not been able to find any drawings.

I have heard of 1 or 2 failures of rudder stock bearings on 10 year old Bavaria sailing boats but don't know about the "pendulum". In this case the head of the stock is held by a locking nut on the aft deck but I am not able to see the bottom bearing assembly.

No idea....

There's self steering gear that works on the "servo pendulum" principle. (e.g. Monitor )

What context is the phrase used in? Has it been translated (possibly badly)?

There is a rudder-stock-mounted self-steering gear design which uses a pendulum - I wonder if this is what you're referring to ?

The place to ask is:

and the bloke who designed it is Jan Alkema who can also be contacted there.

If that isn't it - then can't help, sorry ...

I think that this refers to the bottom bush, it is a Nylon doughnut that is supposed to self align but after time it swells in the water and jambs solid. This makes it hard to force the rudder stock down to slip it out. I believe the recommended bodge is to ream it out with a flap wheel.

The phrase is given as a statement by Bavaria in a sales specification and not associated with self steering, but there is no other explanation. Sales brochures are obviously designed to confuse everyone. I have heard of a Nylon Doughnut before and suspect this is what its all aboiut.

Thanks for your comments everyone.

Diatonic,

Pretty sure it's just a poor translation for something unremarkable - rather like the Cessna "Landomatic" gear = nosewheel tricycle undercarriage!

By the way, from your chosen name, you're not another melodeon playing boater are you?

""you're not another melodeon playing boater are you?""

Is that a Diatonic Button Accordian? I wish, but have not seen any around. Tried a keyboard but boat not big enough. Bought a bigger boat but wife complained so bought a clarinet. Neighbours complained. Bought a bigger bigger boat but got lonely so now have personal mp3 player.

Yes, Diatonic Button Accordeon - that's why it's more popularly called a melodeon! I must admit, though that a concertina would be easier to stow on board but neither is keen on the damp salty conditions.
