    I am going to be building a new trailer for my 80 260 DA. Sea Ray specs say the boat is 5500 lbs empty so I will have to either go with 3 axles or 2 heavier axles. Right now I am leaning towards triple axle, mainly because I am planning a move to florida and I know that 3 axles will make it ride much better going that far. What do you all think that have experiece with both?

    I'm a fan of tri-axles, even on a smaller, lighter boat. I had a Eagle tri-axle built for my 270 Sundeck. The original reason I did that was that I wanted to keep the boat as low as possible to get it in my shop. With the 3 axles I used 14" tires plus the difference in spring height got me a couple inches lower.

    My boat weighed a couple hundred more than yours. The boat pulled so smoothly and with brakes on all axles stopped well. It's a noticeable difference. Whatever you do, don't design your trailer to the limit on tire capacity. I think that's the main cause of a lot of the nightmare stories we hear with tires.

    I have a tandem 10,500lb aluminum w/ 15" tires. I like it due to 2 less tires, wheels, bearings, etc.

    If can go triple do it. I towed this 7,700 lb beast from Austin Texas t San Diego with triple Sea Hawk Aluminum trailer. 14 inch tires, Kodiak brakes on front two axles. A lot of greasing of bearings and crossing fingers. The 270 is 10 foot beam so don't even want to go into the various states oversized load rules!
