We have a Manta that lost its rudder in a move and are trying to find some information as well. So far we have found out that they were manifactured in Cal. and the company is no longer in existance. Half Moon Bay Yatch Club in CA has a web site with a picture of them and another site we have found is Guppy Sailboat Info Page http://www.shortypen.com/boats/pocket/guppy/ If you have any further info we would love to hear about it. Thanks Laura : : '79 14 foot MANTA. Does anyone know anything about this little sail boat? I just bought one and can't find out anything about it. Thanks. Eric :
