Re: Brushless winch

I am very happy to see a viable alternative to the RMG winch on the market and I wish them all success. I am fortunate to work where I do and do have considderable electronic expertise in the other room and so I have adapted an old dead RMG to use a brushless motor and a PIC controller. Mine is no w...

Re: Data transmission from the boat

Gentlemen, I will confess that I had now come across the term ‘Luddites ‘ for a very long time. I assume you mean the group of Lancashire workers that went around breaking machines in the 18th century. Or do you refer to the modern usage - those who are Computer Averse. But back to the discussion at...

Re: Data transmission from the boat

Gentlemen, With respect, simply because this technology is available is no valid reason for utilising it or changing the class rules to accommodate it. Before purchasing such equipment the test firstly the user / skipper should apply is:- Q1/ How will it benefit / improve my sailing? The clear answe...

Hi Brian, I understand that the Stealth can be a particularly tricky boat to set up and one would urge caution when approaching this task.

No No stop - you are about to make an almighty mess. So it did not hold. Regrettably it never will and it was very luck you spotted it. You added micro-balloons, it makes the epoxy brittle and cracks when the boat flexes and flex it will. You probably also did not play too much attention to the epox...

Re: New Nylet Spirit is here! Progress at last!

A few tips • Use a lighter section- there is a 0.5mm wall mast available. Needs very careful hound and spreader positioning but will save 40g just to start with. • Backstay crane should only be long enough to clear, 2mm, the back stay from the roach of the sail- cut off any excess. This will reduce ...

I have been watching this build for what seems an eternity, October 2010, but I guess you are not in a hurry.

Re: Moulded sails -- future rule change?

There is certainly no evidence to suggest that Moulded Sails will make any substantial difference to the IOM Class. The process being trialled by a number of people is fundamentally the same as Vacuum Forming. Given the extremely stable nature of Polyester Film, Melinex or Mylar, the shape of a sail...

Re: Single Panel Molded Sails

• The second part of your question:-

A vote can only be made upon the adoption of a rule change. A rule change can only be proposed by a National Class Association. So if you want to Vote - first motivate a change of rule at your NCA who will bring it to the CA.
