Would a center board help the MKII kayak sailrig point higher into the wind? That is, putting the centerboard, or daggerboard as it were thru the keel line of the kayak as opposed to the aka mounted swiveling one.

I think it might be a little more efficient for windward work. We have a kayak here in the rafters that has a daggerboard trunk for this reason. I know that one sails well, but so do the ones with the rigid leeboard arrangement. I haven't sailed the daggerboard-equipped boat alongside the standard rig so I don't have any comparative data. Once you put in a trunk you've compromised the kayak's kayak-ness. Extra weight, drag from the trunk opening, etc.
