I understand that E 23s were built in fixed keel and centerboard models, but sources list E 23-1 and E 23-2 models. Can anyone tell me the difference? I am specifically wondering if there was a tall rig variation offered, as I have some sails for an E 23 that don't fit my spars - the main is about 1.5' too short on the luff and 1.5' too long on the foot, and the jibs are also too short on the luff. Thanks for any light you can shed on this topic.
