General National 12 chat / mast step position
« on: July 02, 2021, 12:53:28 PM »
OK, I have tried to get this info from searching the forum and elsewhere, but to no avail.

I have noticed that there are two more common mast step positions. A forward position about 110cm from the bow, and a more aft position about 130cm from the bow.

The original Uffa King design was 3 foot 6 inch = 106cm

1/3rd of boat length, which is common in the Merlin, would be 120cm

Is this a design specific difference or does it alter within a hull design?

Is there a commensurate movement of the centre-board?

What are the effects of a more forward mast step and vice versa? Is this to do with benefits of a large jib?

Hi All,

I was a N12 sailor a loooong time ago, with my son in a baggy trousers. It's been 14 years out of sailing (since my crew ended up 6'4"). I am eyeing up a return and saw N3500 availble. I well remember this being the peak of technology back in the day and seeing it at the dinghy show!

My question is - what should I look out for in an old carbon boat like this? does carbon go 'soft', it is after all just resin composite like glass. Does it take in water? What weight should the hull be (without the lead).


General National 12 chat / brand new aardvark carbon boom for sail
« on: April 24, 2010, 02:40:40 PM »
I am posting this here as I can't log into the ad section (it won't let me recover my password)
I'm selling my 75mm round white carbon boom to the highest bidder on ebay. The auction will go live from 6pm Sunday. I will be applying a 150 'buy it now' option, but this will disappear once the first bid is made. So if you really want it for that price, email me before 6pm Sunday.
It is brand new, never been rigged or on a boat. Mike makes these to order for 275 ( So it is a bargain at this price.
It is currently in Saltburn, North East England. It comes in a solid cardboard triangular box, so can be posted. However, it would be better collected or hand delivered by a fellow N12 sailor if possible. I can keep hold of it until this is arranged.
Ring me on 07817362823 or email philipj thefirstdot cosson at ntlworld theseconddot com

(I also have a large and a small drysuit. These are hardly used. They will be going on ebay as well at some time soon.)

General National 12 chat / Smallest car for towing
« on: November 08, 2008, 08:36:41 AM »
Its time for a change in cars. I'm wondering what the smallest car anyone has had success towing a N12 with. I remember seeing a Mini in 2006  but not sure of the engine size.
I don't want this to happen -

General National 12 chat / National12 class rules wiki
« on: July 23, 2008, 07:30:49 PM »
I have gone ahead and done it. Here is a 21st century method of debating/evolving the class rules.

In doing this I have noticed several discrepancies - for example there is a note refering to clasue 5.2.2 (which doesn't exist)

The way I envisage anyone using it is to add explanations or comments to the 'thread' for any individial entry - like the good explanations that are already here about certain rules.
The actual entries can be edited for grammar/spelling etc. at will.
The descriptions of the clauses can be altered at will - these were the best i could do in the time, and i gave up toward the end (when it became too technical)
The content of the clauses could be altered by anybody after debate - like changing the length to 13 feet!
Clauses can be deleted after debate - like 11.7.2

The original entry can always be reverted back to. And of course anybody else can reedit your edit
Enjoy or ignore

General National 12 chat / sails for sale
« on: May 26, 2008, 04:49:19 PM »
FOR SALE - 2004 set of Pinnel and Bax sails; Dacron jib, Pentex main. I bought these from John Meadowcroft last year just before buying a new boat which came with a great set of sails.
I have never used the main and only used the jib once (at Northampton in November 2007). I have decided they ought to be be being used by someone rather than sitting in my garage. They come with battens and a black Pinnel and Bax sail bag. 350 ONO (which is what I paid for them, I believe)
ALSO FOR SALE - an oldish polyester Hyde Mainsail - suitable for training or windy weather - comes with a Hyde sailbag but no battens. 50 ONO
My number is in the book - otherwise email
