Quick Answer
The ideal method for tying a bowline underwater involves using your teeth to hold the standing part of the rope, creating a loop with the working end, and then passing it through the loop from the underside.
Creating a Secure Loop
To tie a bowline underwater, start by creating a loop with the working end of the rope. Hold the loop in place with your non-dominant hand, or ask a partner to hold it for you. Keep the standing part of the rope taut with your teeth, as this will prevent the loop from slipping out of place.
Passing Through the Loop
With the loop held in place, pass the working end of the rope through it from the underside. This is the critical step in creating a bowline. To make it easier, use your free hand to guide the working end through the loop. Aim to pass the working end through the loop in the center, rather than at an angle.
Securing the Bowline
Once the working end has passed through the loop, pull it gently to create tension. This will secure the bowline and create a reliable loop. To check if the bowline is properly tied, try to pull the working end out of the loop. If it’s properly tied, the bowline should hold fast.
