Docking or mooring your vessel can be the most challenging of boating operations. Keep the following in mind for effective docking:
If the wind is in your face, you will need to approach the dock at a steep angle (30°-45°) and swing the boat quickly. Secure the bow first, and then reverse until the stern swings in.
If the wind is at your back, you should approach the dock at a shallow angle (10°-20°), then stop the boat and allow the wind to drift the boat into the dock.
Though anchors are not required by federal law, it is advisable to carry an anchor for both recreational and emergency use.
As a general rule of thumb, your rode should be 7 to 10 times the depth of the water in which you will anchor. You will need more rode in bad weather or rough water.
Always secure the anchor line to a bow cleata metal fitting located on the bow on which a rope can be fastened.. Never tie the line to the stern as the additional weight could bring on water.
