Whoo hoo I sailed the Cherub Daemon today

Looking at the rig, I'm asking myself if the boat might be a little more stable if the mast foot was a little further aft, or perhaps the mast more raked - in the style of the original Bieker Int 14 imports of about 10yrs ago?

Thus more lift from the kite = more stable ride.  That added to the t-foil, would probably stabilise the whole thing pretty well downwind.

As with most designs of this kind, one imagines that the problem isn't generating the power, it appears to be controlling it when it gets hairy.

The bow popping up and down might be just due to the length of the boat and being susceptible to slight pitching movement in very moderate sea states. I'm not making any judgements based on videos, as videos can be very misleading, watch a Tornado in moderate wind conditions on YouTube, it doesn't look too quick but it is pretty quick if you focus on the background. I'm quite impressed by the Daemon and what I've seen build-wise of the GT60 so far and reckon that the selections in April are going to be very interesting.

Nothing to do with being outnumbered. You're just wrong.
