Hi Keith
Its amazing how slow boats look upwind when sailing on there own like this it makes it very difficult to work out how she is actually going. Hopefully over the summer you will get the boat out to a few events for people to judge on the water. Good luck with the boat. Gordon Phantom 1430 |

It seems to me that the thing that would most change your sailing life is nothing to do with the boat or rig but a waterproof, motorised trolley with fat wheels that do not sink into mud, sand or shingle. Add an 'auto' button to drive itself back up the beach after launching and you'd be sorted. Surely there is now some bike-tech you could adapt - did someone not get caught hiding a motor in a road-race bike recently? |

IGRF, the 'big fat head' is there for a purpose, not just to look sexy. Jim Hunt (HD Sails) has designed the sail to provide 'gust response' - so that the leech eases off in a gust, thus depowering the rig. The amount can be adjusted via kicker and Cunningham. With sail no 1, it seemed to work a treat.

I think you'd need a lot less cunningham than me Al |

Yes, I get that and they are useful for the sort of target venue with trees and stuff around for light airs and most normal weight folk will handle them I'm sure. But, personally I'm off the whole idea, once they depower all you have is acres of parasitic drag, when you need them to power up you need a kicker array that would power a yacht, and I guess I'm just 'over' the whole look, it's just a personal viewpoint not being critical per se, we've had' fatter' head sails since the dawn of time in my world and it's only now as my progress down the years in this lark is revealing new downsides to having so much area up there, that my viewpoint has altered. And anyway, what's to stop you chucking up a smaller rag and calling it H3, or H Fire, H Bomb even, it's all the rage these days, then give it a slow handicap and go round the country robbing us mortals of our chocolates.. ![]() |

What would change my life would be a boat lackey, they're normally called crew, but when they go and crock their backs as well, you're in trouble. Yes somebody did recently get caught with an electric assist crank, battery hidden in the down tube, engine in the crank, roadie of course, where else do you get cheats?

Aero sailor jumping in .....
![]() lightness around the boat park blah blah... The fathead sails have made me think as to whether they can be efficient with drag. I totally understand the gust response, but as wind speed goes up and you rely on the head bending off, this must translate into constant drag. Does that mean that a sail without fathead can operate in more wind range with less drag as at is a smoother bleed off? Purely on my own experience in the aero, which has a slight fathead to the sail, there is a definite step between sail sizes. i.e at the top end of a sail size its noticeably quicker than the next size down, but add three knots and its noticeably slower when the head is allowed to fall off. Choosing your largest sail size for a series over several weeks is therefore complex. On the Hadron it appears to have an adjustable forestay, allowing the rig to depower like a supernova. In which case it would carry its sail size across a wider range than on a static rig without having to let the head bend off continuously.
I may be just talking b****cks of course ![]() |
