Hi Jon, glad to hear that you have managed to make some use of the wet weather anyway. Sitting here in my dressing gown with a mug of tea I cannot really give you an accurate measurement of the sail travel ! Suffice it to say that they don't travel out as far as, say a racing yacht on a run. On the loose footed main it doesn't get beyond a broad reach. I only have the main and mizzen sails on the winch and found that having the main sheet travel through the multi block system and the mizzen on a single purchase ie the sheeting line comes up through the deck, travels up to the mizzen boom single block and back to secure to the deck - gives a workable ratio between the two. If anything the mizzen travels a little farther for the same winch rotation but this is an advantage when running as it sets the mizzen out at a better angle. In practice you will probably find that she will quite happily trundle around with only occasional tweaks on the winch. The fore and jib sails are on fixed sheets and look after themselves with the outer jib giving a fine signal when you are pinching the wind too far !
As far as the sheeting leads, I have the main sheeting coming up on the centreline just below the main horse and the mizzen also on the centreline inside the stern. Also the two tackles to the boom head (A bit early in the morning for memory - is it the vangs ?)are also led to the winch with a similar single purchase set up so that both either are heaving or paying ot simultaneously. This gives the upper part of the mainsail a better shape on different sail angles. Sounds more complicated than it is !
Mike
PS To georgo, thanks for the compliment but I think you will find far better models than mine if you search around ! Have you found the website for the Model sailing barge association yet ? There will be more help on your restoration there, possibly. Looking forward to some pics of your progress
Damn now the bloomin' tea has gone cold !
