On my boat, the centreboard seems to have only two positions: fully up or fully down - down only because the rope handle interferes with the top of the case. If I try to set the centreboard partially down, it floats up
It is a carbon fibre board with presumably a foam core. There are pieces of thin plastic glued either side.
On other boats, with wooden boards, I have come across two methods of stopping board rising - adjustable pads either side or a piece of hose on the front edge that is compressed under a plate.
I have tried addiing a gash CD, but that seems to be too thick to fit into the current slot.
Can anyone suggest what I could use with my set up. I don't want to cut into the centreboard case if I can avoid it.
 
thanks

Just a reminder that Desborough SC will be holding its Annual N12 Open on May 10th on our delightful stretch of the Thames at Shepperton. First start is 11.00am - 3 races and 2 to count.
Details on how to find us are on our website www.desboroughsc.org

I acquired a set of unmeasured sails (approx 2010 construction) at the end of last year, and am now about to get a new mast made.
I would need to get both measured properly.
Does it make any difference whether I get the new mast the same as the old one?
What are the constraints? - I think that the sail luff and foot must fit inside the bands on mast and boom. How do the quarter mesurements affect this?
On the sail, can I just measure the distance from tack to clew and from head to tack to check actual size? Is it the straight line distance or does it folow the sail shape?
I have the measurement certificate values for my boat and the donor boat.
 
Would it make sense to make sure that the new mast fits the sail? or match the current certificate?

thanks

General National 12 chat / Bent mast
02 Mar 2014, 01:32
I have been to visit my boat and found, that after the floods, the mast has a considerable bend in it. It is quite neat; just a gentle curve towards the stern between the bottom of the sail track and where the mast comes through the gate. There doesn't appear to be any bend to the side.

The boat is a Baggy Trousers 3342.

The mast is alluminium, I think a Proctor section.

I have several options:


      • do nothing and see what effect it has in practice.

      [/list]
       



          • try to straighten the mast - does anybody have any advice or suggestions?

          [/list]
           



              • buy a second hand replacement - what are the things I need to find out to check whether it is suitable for my boat?

              [/list]
               



                  • use this as an excuse to get a new mast (I shall see what the insurers have to say about this) - who makes good masts, what would suit a baggy?

                  [/list]
                   
                  If I get a replacement mast, will I need to get the boat remeasured?

                  thanks

                  I'm thinking about buying sails for my 12.
                  Please can someone help me and explain the rules for changing sails between boats.

                  In my Baggy Trousers, there is a low stern tank which extends a little under the floor. The centreboard case is pretty low and extends only about 8 - 10" above the floor.

                  After a capsize, on the river at Desborough, the natural water line is about level with the top of the centreboard case or just above depending on the weight of the crew. I have managed to sail out singlehanded, but never with even the lightest of crews.

                  The forward and aft tanks are both empty.

                  Is there some underlying problem with my boat? Are there any simple steps I can take to improve things?

                  I am considering whether adding some thin tubular bags either side of the centreboard would add enough floatation to make a difference, or whether they would be too much in the way; obstructing access to the bailers and operation of the tackle for the jib tension and lowers that run along the floor there.

                  One sugestion is that the boat was put together with sailing on the sea in mind,which would provide more bouancy.

                  The boom on my 12 has a slot running along the top of it, but the clew of the sail is held down by a webbing strop that is tight around the boom and doesn't slide very well.
                  Are there any better ways of setting it up so that it will move more easily?
                  Would this boom originally be for a sail with a bolt rope sewn into the foot?
                  Could I put a slider in instead?
                  I guess that if it was that easy then it would have been tried by the previous owner.

                  The rubber tiller extension joint broke last weekend. Has anybody got any advice how to get the broken part out of the extension and fit the new one?
                  The extension is aluminium with a deep crimp all around about 6mm from the end. Is it possible to get the old piece out without cutting the end off? Can I heat it up and make it softer?
                  I dont think that I can make a new deep crimp if I cut it off, so how can I hold the fitting in?

                  General National 12 chat / Firefly
                  08 Nov 2010, 01:08
                  I was talking to a chap at the sailing club yesterday and he said that the Firefly dinghy was originally a N12 design.
                  I read that it was designed by Uffa King along the lines of the 12 but was it ever a legal N12 design?
                  thanks

                  Is there any way to change the screen name?
                  I've got fed up with my speeling mistook and now I've got a boat it's time for a change.

                  I've been looking for a 12 for a few months now and I've come across a few that don't come with trailer or trolley.
                  How can I decide whether the trailer that I have would be suitable?  I have two trailers - both old and of unknown origin. One I think might have been used for a Firefly. Currently both are used variously with a Mirror and a British Moth.
                  Does it make much difference which 12 design?
                  The trailer question is probably more important as I don't want to drive up to collect and find that the boat wont fit.
                  thanks

                  I'm still looking for a 12 as I have recently joined Desborough SC where this is a popular class. It is a river club with associated fluky winds and resticted waters.

                  I've been looking at this site for a few months. The local fleet is mainly AC boats with a couple of vintage designs.
                  The boat will be for me to sail with my son, or my wife and son when either feels confident enough. We are all fairly light (less than 20 stone combined weight).
                  I'm looking at this stage for a fairly stable design.
                  I would prefer a "plastic" boat to reduce the maintenance.
                  My budget is up to £1000.
                  So far my browsing on various internet sites has turned up several options in my price range and at a reasonable distance - all wooden:

                  a Cheshire Cat in Kent £700
                  1702 - a Vintage Mark 8 in Essex £550
                  3482 - a wooden Man'O'War  £900
                  2692 - a Whisper 4 £800

                  Would any of these be good or particularly bad for my conditions?
                  Does anybody know anything about these particular boats?

                  Would I be better off waiting and saving up for something like a Design 8? (approx £1700)

                  Any other designs to look out for?
                  What is the expected price of different designs second hand?
                  thanks

                  no mast or sails but if anybody wants to follow it up for the records ...
                  I asked the seller and it has 1858 by the centreboard

                  I've recently joined a club with a fleet of 12s and it may be the way to solve my son's problem. I've explained the handicap system to him but he still doesn't get that I can finish half an hour later in my Mirror and still get a decent place, I suspect that if I get something with a low handicap and finish "first" on elapsed time and then get a low place he will feel cheated.
                  This leaves joining the fleet racing i.e. a 12. Most of the 12s are fairly recent but I've just spotted a vintage one not too far away. How competetive will it be for inland river sailing? I suppose that a lot will be down to skill and experience.
                  Is it possible to upgrade rigging on these boats?

                  thanks
