Spinnaker crane......
usually most P30s will have a suitable 'spinnaker crane' attached to the mast head. This is a sturdy structure (arm) at the top of the mast that keeps the head of the spinnaker 'out and away' from the top swivel of roller furling gear (for the jib/genoa). Without a suitable spinnaker crane you will be limited to sailing 'bareheaded' (no jib/genoa) while you totally douse or furl, etc. the genoa ... and once done and cleared, then you raise the spinnaker, etc. Without a crane you risk entangling the light weight head material of the spinnaker INTO the top swivel .. which can totally jamb the spinnaker UP and prevent it from coming down. What happens is the swivel 'rotates back and forth' and 'may' entangle the spinnaker within the swivel. A crane keeps the spinn away from the furling gear. As stated 'most' P30s had a mast crane applied to the mast head... if yours doesnt, consider to mount one.Will save a LOT of 'hassle' (and may prevent the need of going up the mast with a knife in your teeth!). Also, consider an ATN 'tacker' or set of 'parrel beads' to attach the tack of the spinnaker to the forestay ... if you are using furling gear for your genoa --- keeps the tack of the spinn on the centerline and prevents it from 'blowing off to leeward'. As others have posted consider a chute-scoop or sock to help getting over the 'angst' of raising/dousing the spinn. You can also partly reduce the SA with the sock when you are gybing. Lot of 'air-time' with an Aspinn will accelerate the learning curve. Once well up on that curve, forget the sock and simply launch the spinnaker diredtly from the front hatch .... faster, easier and less 'control lines' to get tangled and to trip over. P30s are GREAT boats, an A-Spinn will make her 'fly' even better. ;-)
