Great video John !

Actually the gybe looks pretty good to me. You are keeping the spi drawing, hardly any flapping and certainly no collaps.

But it doen looks to me that you could have sheeted out while rounding the bouy and then have sheeted back in after the bear away and before hoisting the spi. The conditions seem stable enough for that and you will have won 3 seconds of the spi fully drawing. In the video you have the spi flapping and collapsing during this time (when sheeting in the main). In my experience those 3-4 seconds could have costed you a significant amount of covered distance.

But you did a nice hoist and you got some good speed there.
