spinnaker will have bigger 'shoulders', ie more rounded luff / leach than a cruising spinnaker.
Those bigger shoulders makes the sail deeper in the middle, meaning a racing
version should generate more power on deeper sailing angles.
But those bigger shoulders also makes it harded to trim to keep flying at its most effective. The windward one will collapse when not exactly right - so they make more work. The deeper cut also somewhat restricts the shallower angles you can sail it at.
A cruising spinnaker being flatter needs less trimming to keep it flying wihout a hassle - and that same flatness also allows you to fly it usually shyer than you can fly a full racing version.
Trust this is clear.
