Consider an ATN "tacker"

Good for beam reaching and down almost to a broad reach

You can also make something similar by yourself made from 2-1/2"-3"
wooden balls, light steel cable, etc.

Also, a smaller than full size spinnaker usually works best for
'poleless' spinnaker sailing as you can either gybe it through between
the mast and the headstay OR gybe it 'out and around' the headstay.
Out and around, for best results, should have a spinnaker crane
attached to the top of themast .... but for 'easy sailing' you dont
really need one.

Also consider a 'chute scoop' or spinnaker sock to make launching and
take-downs much easier

The above websites are just 'one' manufacturer ... and many others
have 'equivalents'.
