I've been able to test paddle my almost completed Guillemot S&G a couple of times and am curious about the gear I will be able to carry since I decreased the volume of the design and built it heavier than what was probably justified. I'm an experienced canoe tripper, and we canoeists have the concept of freeboard that should be maintained (<6" at the center of a canoe indicates overloading). Is there a similar rule of thumb in kayaking?
