We have launched our Shark24 off the trailer a couple of times, and it hasn't always gone well. We dropped the wheels off the concrete ramp into the mud, and got really stuck. Luckily our sailing guru was able to get a line around the axle and tie a bowline. This took several dives. Siamese has really hit the nail on the head here. You're going to need a long tongue extension and a steep ramp with lots of concrete. Don't forget to check for leaks before you release the boat from the trailer. Best of luck.
