Double Sheet Bend https://www.youtube.com/embed/g2Z7aKwWa6Q The double sheet bend knot shares all the features of a Sheet Bend except that it is a more secure knot. Accordingly, it is the preferred knot of the two.

Sheet Bend https://www.youtube.com/embed/aK-1LJNYTIs The sheet bend knot is used to tie two lines of equal or unequal thickness together. The sheet bend knot can be tied anywhere into another line and therefore it can be used to lengthen or shorten the overall length of a line. Always make your bend (U shaped loop) in the thicker of the two lines.

Clove Hitch The clove hitch is a fast temporary knot for tying a line off to a spar (post). The clove hitch requires constant tension on the line in order to secure the knot. The rocking motion on a bow line secured to a dock post soon causes a clove hitch to untie. Use the clove hitch in limited circumstances. A technique is to add a half hitch after the clove hitch has been tied for additional security. https://www.youtube.com/embed/W_Q0pXg4EmI

Round Turn & Two Half Hitches The round turn & two half hitches is another very useful and often used knot. The round turn two half hitches is a great knot to secure a boat to a dock ring, post or tying fenders onto stanchions. When tying a round turn two half hitches knot, make sure you wrap your half hitches in the same direction. https://www.youtube.com/embed/YxzfbeCT3f0
