One of the first things taught to new cruise participants is line handling – lines are attached to the CTD-rosette to stabilize it during deployment and recovery.  Rough weather & a rolling ship can cause the 800lbs (empty; 363kg) -1500lbs (full; 680kg) CTD-rosette to swing dangerously when the winch lifts it. Taglines allow the CTD-rosette to be deployed safely during these conditions. Tagline training is introduced under calm conditions so participants are prepared if rough weather occurs. 

Important things to remember:
1. Wrap the line around the cleat, careful not to bind on itself when the CTD moves up or down, in or outboard.
  
2. Keep your hands at least 12 inches (30cm) from the cleat as the line slips out.
   
   
3. Be sure to watch for line tangles and do not stand inside a loop. If you see ANY line or wire becoming entangled, be sure to shout out "STOP" to bring attention to the problem.
   
4. Always keep your line tight by pulling out the slack but do not inhibit the CTD’s movement on or off the ship.  A good indicator is the angle of the winch wire – if it is angled towards your cleat then it may be too tight.  When the ship rolls, quickly take up the slack to prevent the CTD from swinging but let line out as the tension increases.
Angling the CTD slightly inboard is acceptable when bringing the CTD-rosette back aboard. Never put yourself between the CTD and an immovable object such as a wall or rail. Watch your toes when the CTD lands – 1500lbs will crush them. Wearing steel-toed boots or shoes is recommended.
 
   
5. The CTD must be secured to the deck or cleat by line or tagline when onboard. The CTD should not be untied from the deck-eyes unless cleated by the taglines. Loop the line around the cleat then under itself when waiting to deploy or while securing the CTD to the deck eyes.
