And then you drove it down the highway?
OvO, if your question was directed at this photo, then yes, I drove it down the highway!
I had to work without power, so I chainsawed the the wood to fit the boat on site. The boat was on jackstands and I had to get it on the trailer myself, so I built a front support, backed under the boat, added rollers, and kept backing till I needed the rear supports. Balance point was a guess. A bit hairy at times, but all went well.
It handled very nicely, up and down New England hills and around sharp bends. The trailer brakes work. Nothing shifted. Of course, I levered up the supports and removed the rollers before setting out. I have a nice truck capable of towing a much larger load.
The photo is at my home, after I delivered it. It's now further back away from trees and tarped in with a clear tarp that makes it bright as day inside. I set the mast (supporting the tarp) up high enough to stand up in the cockpit.
