I think that the jibs on Cherubs have become too big and tend to take control in a bad way.
Going upwind, if you bear off slightly the jib pulls you off further, luff up and it loses lift and the boat ties to luff further.
You end up fighting it with the rudder.
The main does not do this as it is not cleated.
We have got to this situation as we have been pushing the rigs further back to try and make it comfortable to trapeze above the T foil.
Most of the Skiff classes have the same issue.
On the foiling rig for A+E we moved the mast step forward 18” and raked the rig to keep the hounds in the same place. The jib is a lot smaller.
This worked really well from a sailing perspective, and I would have repeated it on a non-foiling boat.
It meant that the compromises of a tracked jib were diminished.
However, I did not foresee the structural implications.
Shortening the distance from the mast foot to the jib tack and increasing the distance from the mast foot to the crew massively increased the leverage on the forestay amplifying the forestay loads and the mast compression.
It did not help that by this stage Alex was double the weight of when we started.
The mast centre section became unstable despite doubling the laminate.
If I had the chance for another iteration, I would have dropped the hounds to regain stability of the centre span, moved the mast foot back about 6” keeping the jib at the same reduced area.
I would have also gone for a round trackless mast and simply attached the main with straps.
Much simpler to build and rig.
We could have added a zip up luff sleeve, but I doubt that it would have gained much.
