Thanks again for the info and as I suspected it would foul a bit.
At this stage I think I will go with fitting up for Genoa running on forestay halyard and see what I think? I will fit about a 750mm track on deck with car centred as best I can for optimum sheet angle with the track fitted I can then allow for moving car with fairlead eye forward if I decide to give a masthead Genoa fly a try as well as being able to perhaps fit a fairlead at very back of track for/if kite ever fitted up and be able to run sheets back to cabin top and winches when/if possibly fitted.
Bob, from what I could see in one of the pics of your boat, it appears you do not have doubled sheets for jib? Is this correct and if so does that work fine with enough purchase to set easy enough?
I really would like to do away with putting blocks on Jib clew, first because I have to buy them(don't have much small stuff hanging around - plenty bigger stuff for keelers but bit too big) and second I still don't like that setup personally

Next query?
I am putting a topping lift on this boat as it does not have one. Be a pain if need to reef, it does have a clip on backstay that can be used at rest to centre boom etc, but not really great for reefing and I don't like the idea of the boom ending up in cockpit when easing off halyard before reefing.
I'm thinking of using 3 or 4 mm spectra so it nice and thin, don't see the point in using anything thicker and this size spectra rated around 400Kg don't think that be a problem either.
I can get spectra down to 2mm - rated to 250KG,r but that is getting a bit to small to handle I think?
I would use double braid but not sure I can get it that small?
Anyone got good reasons not to use??
