my Windrush was a similar boat with no dagger, a jib etc.
It had a boom sheeted arrangement I just loved for that sort of boat.
It had a six to one that ended in a single ratchet slightly forward of the other block on the boom leaving the sheet hanging right where you could grab it.

In heavy wind I would go into the tack.
as soon as the jib back winded I would go over and as I was passing the tiller around the sheet I would let go the sheet and bring the rudders around for the reverse (By bringing the rudders right across it locks them and they act as break stopping too much reverse) I would let go the tiller arm and flick the jib through.
The boat would start to move forward imediatley losing almost no way.
I would let go the jib and grab the mainsheet with both hands. It would have released about 18 inches.
The rudders would have come back to the centre position and the boat would be sailing a little off the wind and accelerating.
I would hand over hand the main in, keeping the acceleration up and grab the tiller and away.
Very quick, very reliable.

It only became reliable because I went out in wind and practiced it time and time again for a half hour getting the sequence just right.
