Bear in mind that this is my first Winter as a liveaboard and the stove has been alight almost continuously for the last month.
I have a tar-like substance dribbling down the outside of the flue, inside the saloon. There's not an enormous amount, and it seems to dry up when it it has dribbled down by around 12-18 inches, presumably because the flue becomes hotter lower down.
Is this normal?

When this happened to us, it transpired the flue had perished around where it goes through the roof. Nothing to be seen until the old one was removed, then it was obvious.
Once the new flue was in, no further problem.
May be other causes, but that's my experience.

The other week mine did the same it was the chimney the inner had rotted out allowing the gunk to run past the rope seal. Replace the chimney problem gone

If the flue was fitted by the previous owner it is possible it was put in upside down ie male end of the joints uppermost which allows stuff to run down the inside face and out of the joint. The joint must be female up.

I think it is the original flue and so has been on the boat for over 30 years. I've had a good look around it, and down it (in the dark with all interior lights on), and I can't see any breaches in it. I'll try to post some photos tomorrow.

As per dogless really. What I have done, in the past, is run a bead of high temperature silicone around the gap where the stuff is coming from (you'll have to leave the stove to go out for a day or two). This should see you through the winter until you can get it sorted properly.
First off though is to check out peterboat's post.

It may also be poor sealing between the roof collar and flue IF you have a single skin chimney or a poorly fitted twin skin one. Condensation forming on the inside of the chimney will run down, often between the collar and chimney and all over the roof/cabin side. If the flue-collar seal has failed it can also run down the outside of the flue. The answer to this is to use a twin wall chimney with the inner diameter slightly smaller than the flue id. so the gunk drops down the flue. Even better insulate the space between the chimney inner and outer skin. I used spray foam, others have recommended lightly crunched up kitchen foul.

I fireproof foamed both my chimneys and can agree with Tony it does help the stoves draw especially the oil bubble stove.
