I shudder to think what would have happened to the boat at 65 mph with a single axle. Check your bearings regularly!
I use a twin axle 8' x 16' foot flat deck trailer to haul my SIB around. The weight of the trailer is probably triple that of the boat and motor. Overkill? - perhaps, but the flat deck works really nicely with the tunnel hull, and I got the trailer dirt cheap. I find that backing this trailer into tight spots is easier with the twin axles and smallish (16") tires becuse the trailer turns more predictably (gradually) than a single axle trailer does.
I had a similar experience to the one Pat described above with having a trailer tire go flat on a highway and it having a minor effect on the handling of the rig. For me it gives some extra peace of mind given the condition of some of the lake access 'roads' in these parts. Also, the handling of a twin axled trailer is much less squirrelly when the roads are icy.
