What rig?

Yes, I mean three feet, not three inches !

English Dave, you are correct about putting rudders on outriggers and using a connecting bar as a handlebar but not about your thoughts with the centre mainsheet.  I want one so I can jamcleat it to something and yet be able to release it quickly if necessary.  I'm not familliar with the Laser2, but will do my homework.  I wondered if a mirror rig would be a bit small?
The stayed vs. unstayed mast arguments are valid, but the canoe is only built from 4mm marine ply (I know coz I built it) and i don't think it would take the stresses involved with an unstayed mast.  The outrigger bracing could be postitioned to take shrouds etconce I had decided on a rig.
When you say a Laser2 rig might be overpowered downwind, are you woried about pitchpoleing?  Me too, but I'm willing to take the risk!

You think I'm mad and you don't even know me!  You should hear my friends' opinions!

Cheers,

Moose

Hi Moose welcome to the forum.

It depends what sort of sailing you are going to do. If you are cruising the broads then an easy handling sail would be best. I guess you want the centre main because you are seated facing forward?

Something like the sail from a Laser2 would do you. You might be a little overpowered downwind depending on where you site the mast. Perhaps a Mirror gaff rig might also be worth considering.

Cats need two rudders because they sail on only one hull at a time. Perhaps I'm wrong but I don't see this happening with your project. Oh, do you mean put them on the outriggers and use  the connecting bar as a sort of handlebar?

An unstayed mast would load up the canoe hull but it would save you from having to over-engineer the bracing that will hold the outriggers. Good luck but I think you're mad!
