Re: What "..shall pass through a 20mm, ring gauge." BOOM F.

Good morning David,

I am aware of your point re Fa(x) and tiny modification will resolve this. I disagree with the rest of your argument. I am not going to continue the debate here until my appeal has been seen and considered by the powers that be.

My best regards,
James

Re: What "..shall pass through a 20mm, ring gauge." BOOM F.

Thank you very much for your input Barry. The intent of the structure is to put screw adjustment on as many controls as possible as I want the precise, fine and repeatable adjustment this gives. The kicker lever gives 7.5:1 ratio doubled with a 2:1 control line giving 15:1. I have no desire to exten...

Re: What "..shall pass through a 20mm, ring gauge." BOOM F.

Hi Barry, Many thanks for your continued interest. It definitely helps focus my mind. It is an integral part of the kicker and is a convenient place to lead its adjustment/control line. It has always been that way and I have called it a control line panel to differentiate it from the kicker lever or...

Re: What "..shall pass through a 20mm, ring gauge." BOOM F.

P.P.S. The compression element of this kicker arrangement is entirely contained within the fitting. The only link to the mast is via the gooseneck fitting and that operates - upper in compression, lower in tension. This is true of all kicking strap arrangements that are combined with the gooseneck f...

Re: What "..shall pass through a 20mm, ring gauge." BOOM F.

Further to my opening post. I believe that the kicker and its fittings do not constitute part of the boom and are therefore not required to pass through the 20mm ring gauge.

Re: Interpretation of IOM CR - wind indicators & telltales

It would be very helpful if salient pro ‘aft of leech’ points on this could be outlined so a fully informed vote can go ahead.

With all due respect to all involved in this discussion, it seems to me that the simplest way to get round this lawyers delight is to specifically include tell tails as an optional fitting.
