Have you any pictures of your sheeting arrangement which side of the plank do you put it?

The seat in pictures is a prototype, it is fixed, their is no slide, it is longer than plank, I think it is same width as a Merlin, so quite a lot of righting for a single sail.
The bar mainsheet block's attached to, is no good, it is a foot trap, it will be changed for a bar attached to centre of seat, this will also allow you to hook foot under to hike
My original plan was to fix block to a hoop, similar to Bahia, and attach either side of centreboard slot.

Interesting looking boat.

Is the mainsheet attached to the same place on the boom as the kicker? Is this attachment on the underside of the boom? The mainsheet looks quite far forward. Does it provide enough leverage being that far forward?

Oh, I'm loving this, finally I can get to tinker about without too much 'class' grief, you've done exactly what I thought it needed just as I fell out of the bloody thing, with that seat, and the centre sheeting. So does the mainsheet block thing slide with the seat or don't you slide it, I'd like some arrangement where you can kick the whole lot out and it self centres when you need to shift back in quickly, considered doing it to the EPS but that sail is so big, there is no where far enough out I could get to compensate for that sail size in the sort of breeze we got today.

Loving what you've done there 423... Inspiring I'm on it, just wish my garage wasn't full of junk so I could start now.

This seat "could slide", approx' 200mm either side of centre, 
you could do a slight modification to your design which would allow same movement that you are getting with plank.
The seat on mine is tortured to increase curve of original plank, (which is underneath).
The Mainsheet block and Kicker is fixed to same bracket, under boom.
I have no difficulty pulling boom with 4to1 sheeting.
The attachment is further forward than is normal, but I could not find another way to keep it out of the way.
The latest mod I am doing is to angle clamcleats, they are a pain to use at the moment, slightest fumble adjustments gone.

I always think an interesting modification if one only wanted a small increase in righting moment would be the little folding winglets they use on some continental Canoe classes like the German Taifun. They're often hinged or pivoted and fold into the boat, and don't create too much disturbance when heeled.

The nice thing about a pukka sliding seat, of course, is that there's nothing on the leeward side.

I can see me ending up with one of those IC things I've always been fascinated by them, but always get put off by the anoraks at the dinghy show, they're so weird you get the feeling you'll get sucked in, they'll whisk you off to some alien planet and conduct experiments on you, that is if their autism ever lets them engage with the unwashed.

So for now I shall have to make do with what has been christened an 'IC for hobbits' by one of the Miracle wags, whose arse I am going to beat in it if I die in the attempt.

Good idea those swivel seat things, has anyone ever managed to make a working self centering thing you kick out with you and it returns if you bend your knees?

Sorry, I'll get my coat and go have a look.
