Actually they did . My 79 has coring in the hull . It was in the form of 2" by 16" plywood strips in a V pattern but it was still a form of coring . This is how a lot of early manufactures started and then at some point scored balsa was developed for marine use . The scoring allowed the resin to impregnate threw and threw allowing a proper bond between wood and glass . This allowed larger surfaces to be cored .
And yes you are correct it is always posable for water to penatrate and cause rot . Water can penetrate raw glass and if you look at a lot of early boats you see that the insides were never finished . Now days all glass is either gel coated or covered with something to prevent water penatration .
I've been working at building a couple different size boats here at our shop and they are 100% wood free but it can be expensive . There are some very well known builders that still use balsa and have no plans of changing material at this point and Pantera is one of them .
Modern day coring would shave 500 ponds off of a 28' but would add $3000 to the build cost .
