My project boat is a 197? Wellcraft 165 Airslot. the floor is rotten and need replacing. What I was wondering is that since the floor is out would it be worth it to install permenante fuel tank under the floor. This would reduce the amount of foam needed, would provide bouancy, create more space topside, and would increase range.<br /><br />Should I do this or stay with the 2 portable 6gal. tanks?
