It can be a bit of a problem launching from the standard Nordica 16 trailer. Even the modest 22inch draft is greater than the depth that most launch ramps are designed for and shallow ramps are even more of a problem. I have always been a little leery of actually putting the rear wheels of my vehicle in the water. A tongue extension was obviously in order. There are dozens of designs but I opted for one of the simpler ones with a simple tube extension with its own ball. It doesn't slide, it doesn't fold. You just disconnect it and it stores on the bed of the trailer. I am pleased to say that it works a treat.
