  1. Gareth. The QBL has significant impact on sail area so you can’t ignore it. If you can get the boat “in racing trim” ie:- on the right waterline as the design then you shouldn’t have a problem with sail area. However, I need to say it’s not just the right waterline length it’s sitting on the design waterline. That should bring all the dimensions into the right ball park. On Serica, by the sound of it, the displacement calcs were either screwed up or more likely the builders either pushed or pulled the beam to alter the displacement, or both. This will significantly alter the displacem
  2. If we are being strict about this, if the boat has had a certificate issued in the dim distant past then the hull can be remeasured to the rule applicable at the time of certificate issue. The certificate records will indicate whether one was issued or not. That’s called Grandfather Rights, however the rig has to comply with the current rule. If it has not been certified then it has to be measured to the current rule. There is absolutely no reason why the boat cannot be measured to the new rule however the boat does need to be in compliance with it. In your case it will need a compliant bump

    PRACC 2021

    To All UK A Class Skippers PRACC 2021 You don’t need me to tell you what a difficult year 2020 has been not only in our personal lives but the changes it has brought to society in general, as that famous saying has it “it aint over yet”. Sailing RA class yachts is not exempt from that either. The MYA has been looking in depth at what would have been 2020’s national racing calendar and has come to the same conclusion as most of us. In that there were too many events in a fixed period if time. Also, now with all that’s going on the emphasis has got to be in building up club sailing. Along with o
  4. A Class Racing in 2020 Fellow sailors, it has indeed been a very strange year so far and it is only very slowly getting better. We now need to look at the way forward, which of necessity will be slow, first we need the A’s out on the water at your clubs, if you do not already do it organise regular A Class sailing and racing days, I don’t actually think we can run much in the way of large events for some time and to this end the intention is to cancel the A Class National Championships for 2020, these will now move to 2021 at Manor Park at a similar time of year, we also are intending to
  5. Richard, if you are in the Poole area a call to Peter Wiles at PJ Sails may help you. Peters number is in his supplier banner on this site.
  6. John. No reason not to. You need to ask yourself the question would the gain you make to windward by pointing higher out way the reduced off wind performance. As the majority of a radio course is off wind then the swing A rig will come out best over the course. That’s why the fleet uses swing rigs for A suit. When wind gets stiffer the conventional rigs work better across the range. You may have seen that swing rigs are set more forward in the hull that increases the tendency to push the bow down and fir the boat to trip up and the wind speed increases. The conventional rig is far easier to h
  7. Richard, to add to Mikes last posting, both my current 6’s, which both date back to the ‘80’s and all previous other 6’s of mine have had a fin box and removable fin/ballast. Both of my 6’s are currently competitive, if I can get to start a race without breaking anything that is. That’s a separate tale. The main area where performance gain can be made is in changes and alterations to the appendages. You can’t make those changes easily if the fin is fixed. Obviuously the choice is yours. I understand that yours may be an old boat but when we get back to sailing again there is no reason why you
  8. Richard. That’s a very difficult question to answer there are many variables For instance one design maybe 15kg of displacement with 1500sq ins of sail area. And another may be 12 Kg with 1300. Both would be equally competitive. The rule is very good providing an equal competitive basis for all backed up with measurement. If you want to see what the full rig is like I suggest that you down load the class rule from the MYA website and take a look at the drawings. That should give you a clue and if you need an explanation you can always give me a ring. My contact details are on the SmartWinch
  9. Martin. Please have another look at the manual provided the every new RMG winch and you will see that setup is a two stage process. The first stage is to calibrate the winch to transmitter by knowing what is the full extent of the stick movement. This is a process applicable to the set up of all electronic speed controllers. The second stage of set up is to set the travel distance from the sheeted in position. Once set it remains unless you want to reset up the winch. You can use the transmitter settings as you suggest but that requires knowledge of the transmitter settings that vary from e
  10. You have my phone number on the SmartWinch banner on this site . Give me a ring and I’ll talk you through it. It’s easy, in set up you are doing two things, first you are calibrating your winch to the transmitter so the winch knows what the full extent of the stick movement is and secondly you are setting the travel distance you want. You can also do this through transmitter settings but it’s quicker, easier and repeatable by doing it through the winch. Bill
  11. In view of the rapidly evolving and fluid situation concerning Covid19 Bournville RS&MBC has decided to postpone the event until later in the year. At the moment the club is considering the weekends of the Autumn half term. We will keep you posted..
  12. I may have a vested interest being a supplier of RMG products but I’d be a bit wary of using a servo based winch in an A Class. PJ have an adapted servo based winch that can be used and have been well tried and tested Maybe ok with an IOM and similar but worth second thoughts for anything that has a decent amount of sail. As ever you can always ring me if you want to have an unbiased talk about winch things. My advert regularly pops up on these pages (Smartwinch)
  13. You could try the Component Shop who are very helpful and will fit XT connectors fir you
  14. Dave, the answer to your question is simple, there ain’t any. It’s a piece of kit that has got to do a job and there are many and various types. They come in all shapes and sizes dependent on what you are using it in. Little ones for 36’s, big ones for A’s and anything in between. Roger Stollery published his design and you can ask him for a copy. The Clem Edwards ones are very accurate and easy to use but are like rocking horse p*** to find. Ken Jones made an effective one out of wire and again examples are hard to find. The there are the Fred Shepherd ones, moving carriages, and the Corby’s
  15. Just a quick note to say the RMG switch is IP65 rated, that means it will work in a wet environment but not designed to operate fully submerged. When returned to us it was working but it could not be guaranteed for how long hence replacement was the safe option.
