No offense Malc but I strongly disagree with your recommendation for those dog ties. Dog ties don't work it big wind. For mud or grass I use a 3ft trailer tie down available at any trailer supply store. I just tie it to the dolphin striker but creep is possible with this system. In sand an old tire or a large cinder block buried is recommended.
In hurracane type winds take the mast down and put the boat back in the dunes so that it is somewhat protected from the direct blast of wind.
Always tie your boat down. If not for yourself for the guy next to you that you will fall on!!!
