Colin, commiserations.
This probably won't help, but I do still have the self-tacking jib from my Storm Petrel 'Cadenza' from before I re-rigged her. You would be welcome to it, but a bit of a pocket hanky for your boat, I guess. A storm (self-tacking) jib perhaps? (The pun was unintentional and has just dawned on me.)
I'll dig it out and measure it up if it's of any interest, but it obviously won't meet your 'fair winds and prosperous voyage' needs. Might start a trend?!
