I am intending to leave it on a drying estuary mooring in the Dee Estuary at West Kirby.
It is quite exposed and I am a little concerned about leaving the rudder in place due to the windage on the large blade especially if the wind was to move to the side of the boat.
First of all, has anyone got experience in similar situations and how easy is it to remove and reinstate the rudder to the boat.
The rudder is heavy and it would be very awkward to hold it in the right position and place the pivot bolt when hanging over the stern.
We have a drying mud berth ,obviously steadier than a swinging morning,but what we do to is to firstly use the uphaul to its limit and then to reduce its projection , make it very visible and make sure that it cannot drop we hoist it to the limit of its rotation ( 45 ish) by using a separate lassoed line tied to the pushpit.
If you are concerned about windage and the boat rotating then some people use a streamed bucket or similat stern drag to damp this down.But that is normally more of an issue when you have a lot of anchor rope 'scope' deployed for a lot of depth and large tidal range .
A heavier mooring riser or the simple addition of some chain to the riser would give drag to stop it wandering before it settled but I think it is the shallow hull profile and high freeboard that provides windage effect,rather than the rudder blade.The blade itself is not troubled by the wind.

But I agree with Peter, removing and replacing the rudder is not that quick.
