Howdy,I've got a 1970 25' Venture/Macgregor with a missing keel and jib.I'm really hoping someone will have the dimensions for a keel since I can build one fairly easily. I'd also appreciate a source for used jibs. I'm not real fussy about the apprearance as I just want to take it out for a spin under full sail.Thanks,Jehmiah of Sonoma County CA USA
