Which knot is best for joining two ropes of different diameters?

• A. Reef knot
• B. Bowline
• C. Sheet bend
• D. Clove hitch

Answer: (C)

When you need to join two lines that aren’t the same thickness, you want a knot that distributes the load between both ropes and resists slipping. The sheet bend does exactly that: you form a bend with the larger rope and thread the end of the smaller rope up through the bend, around the back, and under the wrap, then pull tight. This arrangement grips both lines well even if one is much thicker, and it’s relatively easy to untie after loading. For extra security with slick or very different-sized ropes, you can use a doubled sheet bend. Other knots aren’t as well suited for joining different diameters. A reef knot is prone to capsizing or slipping when the rope diameters differ, so it’s unreliable for this purpose. A bowline creates a fixed loop, not a splice to another rope. A clove hitch is good for attaching a rope to a post or spar, but it can slip if the load shifts and isn’t meant for joining two lines.
