The point on the DC compare is if you take care of an old boat, there really should be no issues. DC boats capsize and sink in short order too. Singling out the age of boat as a major problem is short sighted imo.
The only fishing boat company (that I’m aware of) that advertises upright flotation is Ranger. If there are others, let me know.
I’ll just say that if you are sitting here reading this post thinking “That can/will never happen to me”, you are sorely wrong. Keep a healthy fear of big water in small boats!
