With sail no 1, it seemed to work a treat.

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..

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

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?

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.

It used to be possible to embed a you tube video, but I can't remember exactly the code.. Any way here's that video of the launch, big fat head sail puts me off it has to be said but other than that, it looks a super boat.



So that big gap is where the video should be, try cllcking the blue link

Edit, got it sorted..

Dear me iGRF, My dinghy park seems like yours, wet ,grassy and muddy, the Hadron and H2 are both light boats and I can move mine around in the said boat park with ease. That was also one of my criteria, ease of onshore handling. Single handers by my definition shouldn't need a team to move them around off water. The sail on mine is near 10sq. m. the H2 is slightly smaller, but by  use of sail controls can be de powered and the carbon mast deflects nicely to allow the same. The video shot by Keith on You tube showing H2's first sail shows its handling ease. The H2 could be sailed competitively in a biting nasty cold squally race, particularly with the helm wearing adequate kit. I can honestly say H2 is not a monster boat or has a monster rig. That again was another of Keiths aims to keep weight down to make the boat usable by as many as possible. Looks can be and are deceiving. Smile

The pertinent question that needs asking, is what size is the sail, boats themselves by and large don't determine the size of the helm, it's the rig and more importantly wether the damn thing can be sufficiently depowered.

My logic was always, it didn't really matter, because most of the dinghy things I had observed was that if it's that windy they don't race anyway. Now of late that has proven not to be true, even found myself breaking every rule I set 20 years ago now about not going out in sub 10 degrees in wind exceeding 10 knots for fear of getting those infernal hot hurts that agonise those of us that have to hold the sail up by the boom when racing. But I'm now lucky enough to have a boat with a rig that does depower sufficient that I can get round in fair order in a biting cold nasty squally race, and that's what I now look for in a boat.

That and of course it truly being capable of my hauling it into and out of the water and if it's anything like yesterday with almost the entire boat park underwater in slippy slimy mud, just getting enough traction to haul it around. These are the real world problems, it's one thing handling the bloody things on the water, but hauling their nasty arses around boat parks and up slipways and that was what ruled that H2 out for me when i first set eyes on it, nice enough that it might be in other departments, it looked like a big old monster rig and it was most certainly a monster of a boat for one person to haul about.

Having said all that there are plenty of bigger younger and stronger blokes about, I'd say it will make a good chariot for the disaffected Phantomeer, until such times as the b**tards on the PYAG take a dislike to it.

Gentlemen gentlemen, I have no commercial interest in the Hadron H2, however I do own Hadron 21 as displayed at 2014 RYA Dinghy Show and on Keith's website. I have sailed and owned any number of single and doublehanders in my 60+ years and I can honestly say if Keith hadn't designed the Hadron in the first instance and Simon hadn't built it for me, I was going to give up sailing. My boat is of epoxied wood construction with carbon spars and is quite one of the nicest most comfortable dinghies I have sailed. I can whole heartedly recommend this dinghy to all as given a little thought with the rig controls it can be powered up and down to suit a wide range of weights and sizes. I am looking forward to seeing H2 at the Dinghy Show though. Clap
