No way is really easy, just a pain in the a$$... Takevyour boat to the public launch then have a friend drive to your local scale for a weight. In the mean time test drive your boat to get familiar. When your friend gets back, liad upvthe boat and go back to the scale. Subtract the smaller weight from the larger and you have the boat weight. Now, if you live in a state where your trailer weight is needed, then have your friend unhook the trailer while at the scale, get the trailer weight then hook it back up and come get you at the launch ramp!! Now you will have all the weights you need....boat, trailer, boat with trailer to figure the tongue weight !!!
