For myself, docking in windy situations can be nerve racking. The old adage is to only dock as fast as your willing to hit the pier, and for me this means slow as hell.&lt;p&gt;I always let guests know exactly what I want them to do, and to your point, it&amp;#x27;s mainly to sit tight and let me focus.</text></comment>
