I'm trying to help a friend with selling their boat, but I don't know the production date on it.
Someone who said he was a former Hobie dealer said the serial # is on the back end of the hulls and I can find out the date from them. But this boat has no #'s on the back of the hulls, just a sticker with a triangle inside a circular field on the port hull to the left of the rudder mount. See photos:


Crawling around the boat, I did see "Jan 1979" stamp-embossed into the edge of the trampoline vinyl near the center of the tramp crossbar. See photo:

The weathering of the boat and the tramp seem to synch up, which makes it look like the tramp is original to the boat, but am not completely sure if I can depend on that as the date of production for the boat also.
One other question, are the rudders shown below on this boat EPO rudders? The shape looks like the EPOs I've seen on Google images I've seen, but the finish and label(s) are gone to know for sure.


Any input on the production date and/or the rudder questions on this boat would be great. Thanks a bunch
