Spinnaker size for Drascum Longboat Cruiser

[BCSailer]

Hello,
I have a 1973 Drascum Longboat Cruiser (approx. 21 ft long). I want to get a symmetrical spinnaker for it but I can't figure out what size is best. Does anyone know where I can find this information? Thanks!

I have seen spinnakers cut for boats with exact (original) spinnaker sail size unknown. The sailmaker made the sail as long on the center as the distance from the mast top fitting to the bow, minus about 10 inches.


Pls mind spinnakers are not oh so very nice to fly and douse - perhaps twin jibs poled out are a better choice for your boat. (?)
