Devika is an Excalibur 26, hull number 301, made by Iona Yachts in 1975. She has two spinnakers, I sail single or short handed, so I mostly use the 150 genoas with a Harken roller furler.
If you are still looking for pictures regarding spinnaker set up, I can send you some.
Because I sail solo I was thinking of trying a spinnaker sock - but I also would like to look into a gennaker(spelling?).
You can check out Devika at my site David Kadison's GalacticDrifter 2012
