Ron,

thanks! I did check the slop without the jib hoisted. I'll also check if there's as much movement when the jib is up and the rig is tight.

On the other hand, I started thinking about stiffening the boat when I noticed the slop while out on the water

You're probably right that it doesn't have a huge impact on performance - it does bug me, though. And it feels kind of squishy when hopping those waves.

Regards,
