  1. Val, I believe Charles Smith of the Vintage Model Yacht Group is trying to reconstruct the lost 6M register and also has another project on older 6M yachts. It might be worth you contacting him on tradboat2017@gmail.com
  2. Derek, It would have been Serica 2, K1000, that Norman Hatfield was sailing in 1979. Serica 1 was transferred to Dr J S Rix at Poole in 1974. Serica 2 was registered to Norman Hatfield as owner in 1976, with Arthur Levison credited as designer and Belton/Hatfield as builders. Best regards Gareth
  3. The Serica rating saga The saga of Serica’s rating measurements is complicated, confusing and in some cases contradictory. It is not helped by the fact that there are three A class yachts named Serica. However for Derek, Bill and any other A class anoraks out there I will try and explain the story as best I have been able to uncover it. The original Serica, henceforth to be known as Serica 1, registered as K750, was designed by Bill Daniels and built by Arthur Levison for Norman Hatfield. When we acquired our hull in 2015, we were loaned the original Serica drawing, signed and d
  4. Bill, Thanks for that information. I realise it's a bit cavalier to ignore QBL but Bill Daniels original calculations suggested the penalty was small so i decided to simplify matters and ignore it. However maybe that was part of his original mistake as it seems to be well established that there was a major error in the original Serica design calculations that he did back in 1955/56. I think the most likely explanation, as you say, is that either Arthur Levison or John Gale changed the hull shape of what became our Serica 3, or something else happened during the 45 years or so when it w
  5. Thanks for that Bill, it pretty well confirms what I thought was the situation. I doubt that I will get Phaedra officially measured. I will probably do what I did with Serica III and do some basic measurements myself, weight, waterline length, freeboard and draught and then work out the permissible sail area. If it comes close to the John Lewis figures I might reduce the ballast weight a bit to get the design sail area. I will leave QBL and all the other complicated stuff for someone else to worry about. Hopefully I wont have the same problem that I did with Serica III. Norman Hatfi

    Frank Russell does a 'modern' 6m plan for a design called Cerberus. There is a link to his website here :-http://www.frankrusselldesign.com/plans/ I recently saw a video of one sailing in the UK and there is a link to it here:- https://www.facebook.com/984091914998651/posts/4550253138382493 You can probably contact the builder for information via the Facebook page.
  7. We have used knitted bow bumpers on a number of our restored vintage yachts (usually made by my wife). I think it would work quite well on our A class, particularly with a small sponge rubber ball underneath, partially impaled on the point of the bow. However, as you say, it probably won't be strictly in accordance with the latest class rules We have found that a length of hook type Velcro stuck on the stem is quite effective at stopping the knitted bumpers riding up or down the stem. It is not necessary to have a piece of loop Velcro on the bumper, the hook type alone will grip it.
  8. During the Marblehead discussion we had last year it was apparent that there were two sides to the coin. Owners of modern, measured boats may not mind competing with unmeasured 'classics' on the grounds that their significant performance advantage would probably outweigh the fact that the classic might have a bit more sail area or waterline length than the class rules allow. However the owners of a lightweight, expensive and relatively fragile A class boat might be reluctant to risk it being rammed by an old 67 pound monster with a less than ideal bow bumper.
  9. I am just starting to progress the build of an A class hull that my wife and I acquired about 3 months ago. It is a 1970 John Lewis design, Phaedra 2, possibly one of the most beautiful A class designs ever, or at least I think so. We bought the hull as a bare shell, no deck beams or anything above, and a nicely cast lead keel, weighing 53 pounds. I have been pondering whether to build the boat to be fully compliant with the A class rules and get it measured and registered on completion, perhaps with a view to competing in the classic group of some vane sailing events. We had the same iss
  10. I spoke to Frank about a week ago to order some fittings, which arrived a couple of days later. We also discussed a set of sails and mast for an A class yacht, to be ordered in a couple of months and he did not mention any intention to retire.

    36R Information

    Hi John, Thanks for responding to my 36R query. In the absence of any feedback when I first posted the question I went ahead and finished the yacht using the supplied keel weight 'as is' on the basis that if the worst came to the worst, I could shave some lead off the sides of the weight. In sailing condition with the vane fitted, the bottom of the stem and transom are both slightly below the water line, probably by about 5 mm. I spoke to Ray Baker at Gosport last August and he suggested the boat is a bit heavy and it would be worth reducing the ballast weight to get them both just at
  12. Your yachts look like a 1970 Roger Stollery design called Bloodaxe.
  13. You could well be right there tiggy_cat Gareth
  14. Hi Paul, I think the winch would have driven a closed loop above the deck with the lines coming from the winch drum, through the deck via the two plastic tubes and round a pulley system on the deck. We have a Marblehead with a similar system, coincidentally also with a Nylet sailwinch. I have attached a photo below, its not as complicated as it looks. The sheets for the main sail and jib would be attached to the closed loop. I guess the aluminium tube is a telescopic main sheet post so that the sheet can be guided to a point just below the attachment to the mainsail boom. On the Marb

    36R Information

    I have tried putting the hull in our pond with the keel weight in approximately the correct position. The water line came up to less than 10 mm above the bottom of the stem and just on the bottom edge of the transom. On this basis I think the weight will probably be OK after all, provided I fix it in the correct location longitudinally on the centreline. However any advice would be gratefully received. Gareth

    36R Information

    I have been given a bare fibre-glass 36R hull which I would like to build as a vane steered model. I have been told the hull is a Jagermeister by Martin Dovey but unfortunately he no longer has any drawings of that design, which is about 30 years old. The hull came with a keel weight which seems to my inexpert eye to be a bit on the heavy side at 3.75 kg. Does anyone have any information on this design or could anyone advise me whether the keel weight is likely to be correct? Gareth Jones
