I recently trailered Lone Star #367. The trailer had a built-in support for the mast near the front of the trailer. I rested the top of the mast on the stern rail and padded it well. Not an ideal setup but it worked, I'd have preferred a better support at the stern. I pulled it with a Ford F-250 diesel pickup. I wouldn't use anything lighter or with less torque. A friend hauled his J105 to the Chicago NAs with a Ford Excursion. Keep in mind you're hauling a 7000lb boat on a 1500lb trailer so you need torque. Good luck!
