Took the boat to the water for the first time. Everything went OK --
Well, not quite. I didn't lock the hitch coupler correctly, and the hitch fell off when I was doing 60mph on the freeway! Anyway, I was able to slow down and stop on the side of the road.
The bottom of the trailer's tongue had a metal bracket that probably was designed to protect the tongue in this case -- well it worked. The bracket made a long scratch on the freeway, and part of it melted, but the tongue itself, and the tongue jack, was not damaged.
My friend and I were scared to death, but such a small incidence was not enough to stop our boat launch. So we hitched up the trailer, this time to make sure that it was locked in place. And we went to Redwood City to launch the boat.
The boat drive itself was uneventful. I had to limit the rev to under 3000rpm since the motor is still in break-in period.
When we recovered the boat we couldn't back down the trailer straight into the water. After a few times we gave up and winched the boat in while the trailer was jackknifed.
If you think this was fun enough, well it wasn't. We managed to lock ourselves out of the car, with the car's engine running, and a tide coming in. We called my insurance company and someone came to unlock the car, when the water rose to about 1 inch below my car's tail pipe.
So, I will call this a successful event!
