I bought a J/105 recently (a 34' racing boat) that came with a large inventory of sails. This spinnaker was made by Doyle Sails and is in excellent condition. It does not appear to have every been used. It is not the 'class' spinnaker, meaning it does not have a patch sewn onto it indicating that it can be used for 'one design' J/105 racing, it is labeled as a PHRF spinnaker. Its measurements are:
Luff 47' 2"
Leach 38'4"
Foot 24' 8"
The spinnaker is rigged with a sock, or snuffer, made by 'Black Box'. The snuffer is 35' long and appears to be unused. This is a great setup for a 30-40' boat who wants to sail an asymmetric spinnaker short-handed. New, this would be a $6000 sail with a $500 sock. Buy them both for $2000. I'm willing to separate them if you want just the spinnaker or just the snuffer.
