no, and no. You have to go out on the bow to get a spinnaker sleeve snuffer to work and even then, there is a rediculous amount of windage up there. The tacker thing depends on a headstay and again, you probably need to go up on the bow to set it up (not practical on a cat)...we all double slot with spinnakers leaving our jibs up so you have two slots; one between the main and the jib, and the other between the jib and the spinnaker. Mo power and mo efficiency.
