original 60,70s seacraft cunstruction?

[hugo]

what type of wood and resine were used in the original boats back in the 60,s and 70,s? i am wondering why huge diffrences in transom building methods. didnt the original ones last better than 30 years or so? i know i am in need of one done and have been reading as much as could about the subject with no prior experiance on the matter, and its enough to make you scatter brained with all the diffrent types of materials available. i am a very handy guy and im not worried about trying to possibly take this project on, im just trying to understand which method is best and not going to keep my kids from attending a good school one day. i cant beleive the diffrences in prices for this stuff. how long is a wood and poly resin transom good for?

sorry if i am ranting a little but i just bought this boat and was told the transom was done a few years ago, i used it 7-8 times and have a crack and a flexing transom, could strangle that guy!
anyway....
thanks everyone.
