Rudder design

[davidkeir]

Can anyone provide a picture / technical drawing of a typical rudder placement in relation to hull/***** and rear of boat.

I off course am after the typical broads cruiser type.

I understand that every manufacturer would vary, but the basics should be the same?

I should add, it does not need to be 100 percent accurate,

i only require it to create an understanding of a bigger issue.

Rudders vary wildly as do their fitment, from fully balanced to simple "flag" type, fittings from simple pintles to fully skeg protcted. I have uploaded a useful document for you.

So am i right in thinking that most broads cruiser type rudder will be 'set back' from the stern of the boat.

Ie the stern offers a degree of protection whilst reversing the boat.

And the ***** will protect whilst going forward.

with the most vurnerable time being during stern swinging at speed?

David is right in that it depends what sort of cruiser it is as to what rudder arrangement it will have.

A quick net search reveals a couple:

All these have some sort of Skeg but that is not to say the one you were on did.

It is difficult to say, but I seriously doubt any displacement cruiser would have any part of the rudder projecting beyond the transom, as for protection forward, if there is a bit of a keel and the rudder does not project below it then it would be protected, if it is a hung rudder without a keel then I doubt it would recieve any damage without the prop getting whacked too if going forward. Really without a line drawing of the particular boat it is a bit difficult to be more certain.

This any good. A typical 1950s' Broads cruiser.

I am gratefull for everyones help.

Rod - i would appreciate those images, they would go a long way to helping me.

My rudder on my Freeman does extend beyond the transom. I was quite surprised by that. It's protected by the bathing platformso it's ok but otherwise there would be a risk of clobbering it on a quay if mooring stern on.

This is my first post from 'phone so apologies if it hasn't formatted correctly.
