Own a 19 foot semi V Alumacraft T195 for my big boat down here. It is riveted. This is the 9th year I owned it and hull is as dry as a bone.
I wouldn't hesitate to own another riveted boat. Not everything needs to be a welded super duty to last 15-20 years.
Thought you use to have a Wooldridge and a Seasport?
I did when we lived in Alaska
24 foot Sea Sport XL with a 496 inboard and duoprop
23 foot Alaskan with a 200 hp Optimax prop for the Koyukuk
Also owned a 25 foot Thunderjet inboard jet with a 496. Man that thing sucked up the gas. 1 mpg when loaded.
