When you check Catarafts be sure to seriously look at the urethane tubes, that and glide like no other boats. They are by far the most durable too.Look at different frame designs I bought a mig welder to do my own frames , the skys the limit, anchor systems, heaters , I even mounted a fishing buddie II fish finder it works awsome. If you need any info on tubes or frame design e- mail me glad to help.. Tight Lines...
