It all comes down to what you buy and how you look after it. My 25 year old now Seasport has never had the floor or transom redone and is still solid. It sits outside year round and being a charter boat its entire life has had way more than normal use. Look after it and stay on top of maintenance and a glass boat will last a lifetime. I'm also still running 1997 Yami 2 strokes..others have re-powered 3 times in 15 years with expensive 4 strokes which are way more complicated to work on. . Most of my money has stayed in my pocket.
