Lovely model John.
Does she have a ballast keel or internal ballast?
Looking forward to the pics tomorrow.
Any chance of a video?

With reference to the ballast if its the later be very very careful.
Lovely model  :-)) .

Thanks guys, Ned I can just about put pictures on mayhem
I would not know where to start in putting a video on.
Maybe later when I have caught up with the required technology.
She has a drop keel I will include it in my photo,s tomorrow
she also has all sails working.

Hi guys,lake unfrozen,pictures as promised.the last one shows the drop keel.
She sails beautifully, I am well pleased with my build and at 1/35th scale is
easy to fit in the car.Just a few things to make and fit e.g. dingy etc.
Hope you like the pick,s

Looks great well done. :-)) In terms of please and time on the water sailing my Thames sailing barge has given me the greatest reward.

I take it I'm barely seeing a flase rudder in the last shot?

Well spotted Andy, yes I have built a perspex rudder extension
It fits in-between the 2 rudder sides,(like a large tongue and groove).

Nice model John. :-))
It looks beautiful on the water.
Presumably this is the barge you were referring to when we had our dialogue several months ago.

What's the ' weight and how much of it is in the bolt-on? fin  ?

Lovely Job, wish she was mine! Not being nit picking, but she seems down at the bows slightly, or is it just me?
Title: Re: Thames Coastal Barge
Post by: Netleyned on January 16, 2014, 12:52:03 PM

Nordsee,
I think the yellow line on the rubbing strake draws the eye and makes it appear she is slightly bows down.
Overall she looks fine so I think it might just be an optical illusion.

Post by: john44 on January 16, 2014, 02:26:43 PM
Yes Ned you are right, on the water the yellow line does draw your eyes
to make her LOOK down at the bows but she is really more
 down at the stern.

thank you all for the kind comments

Lovely model John,
Like the idea of the 'view' down the hatch, also that sheeting system on the mizzen is a good idea that should avoid the tangling around the rudder head as mine does !
As the rudder is unbalanced, I decided to make my perspex extension have a small area forward of the pivot, thereby making it a balanced rudder. Might be worrying over nothing but I didn't want to find out the hard way ! You can barely make it out on the pic, I have a close up on my other computer somewhere if you are interested

regards

Mike

Hi Mike,
 that is a nice looking model,any more photo,s of her?
I can barley make out the balanced rudder
I would be interested in a better view of it,
What scale is she?
Has she got a motor & prop fitted I can,t see one?

regards

Hi John
Thanks for the compliment. She his a bit bigger at 1:24 . I will post a close up of the rudder once I master the picture posting again !
She didn't have a prop in the picture but I recently fitted one after a few close calls trying to tack off distant concrete pond sides ! As the weather took a nose dive after I finished, I have yet to try it out. Thanks to a club member giving me a book on the sailing barges, I discovered that the Will was built to take a prop on the centre line, unlike most others which had to fit an off centre shaft, so I avoided a fau pas there !

Regards

Mike

Hi Mike,does she also have a drop keel?

john
Title: Re: Thames Coastal Barge
Post by: MikeK on January 17, 2014, 10:21:23 PM
Hi John
She has a removable fin,much the same as yours. When I built her I made an unwieldy fin similar to the old yacht design which attached via 3 piano wire rods through  brass tubes up through the keelson. Turned out to be near impossible to insert in line supporting the weight of the lead at the same time ! I treated myself to an A Class fin mounting from PJSails and chopped the fin down to the modern racing yacht type, which improved the ability to turn plus making the barge ready at the lake easier.
All we need now is sunny days to try it all out !

looks as though we could have a pair of coastal barges sailing locally sometime this year , ive been rebuilding one for just over a year and hit a stumbling block at the drop keel and rudder extentsion ! jon

Hi Jon
Will get you some pics as soon as a waterproof camera is not required ! I presume you sail at Southsea ? I have never been there yet as I joined the Gosport MBC, which is closer to me.
I have just checked PJSails online catalogue and it mentioned carbon tube for A boat fin at 15, but its probably more now as the list is 2011. It should do the trick, depending on what has been done on the hull before.
Cheers

Mike

Hi John and jon (!)
Found these old pics and managed eventually to fit them here !
The fin is the original one with 3 piano wire attachments which proved far too finicky to line up when holding the weight of the fin, boat and wind thrown in ! As mentioned I took a saw to the whole thing and now have a normal fin design and the PJSails carbon fibre tube system.
If anyone wants pics on the PJ thing let me know. The rudder extension is a bit of perspex, held on by the home (poorly)made bracket and kept in line with a couple of brass pins glued into the perspex and pilot holes in the rudder bottom. The rudder itself is overscale already as I realised when building that the scaled down rudder would not be big enough, so I sketched a larger design on to the plan until I reached what I thought was still ok to the eye. In the first strong blow when she ploughed on straight towards the concrete with the rudder hard over and nothing happening - helped no doubt by that big fin- I decided an extension was the answer. I designed it to be removed so she could stand on her bottom, but as it is carried in the car on her side and lives on a folding cradle, it never gets removed.

Regards to all

Mike


PS do you still want the all up weight of the fin/lead jon ?

hi mike , yes i sail at southsea with the portsmouth model yacht racing club on a saturday morning ( plus wednesday eves in the summer )  yes if you can give me a rough idea of the bulb weight and how far its hanging under the hull it would be useful please

hi mike , progress this end has been a little slow again , although ive managed to seal the inner hull , paint the outer hull and glue the deck to the frames , next task is the comings around the hatches and the sheet guides . how far out do the sails move from the centre line ?

Title: Re: Thames Coastal Barge
Post by: MikeK on February 21, 2014, 09:13:09 AM
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 !
