Hi chrispy
Hard to know what to say other than express sympathy with what your family must have gone through and say that tragedies like this are avoidable. I know nothing about what happened in this situation so won't comment, other than address the following points about safety.
Two points...(1) Can the kite be taken off first to avoid this?
Generally not - the safest way to land a kite is standing on the edge of the water with someone to catch it for you after you have explained to them the only way to hold it (in the middle at the front). Other points to note:
- Only go kiting when the wind is across the beach so you just get dragged down the beach if you lose control, rather than out to sea or onto land.
- Make sure the coast is clear downwind of you at all times - no people, fishermen, rocks, obstacles etc of any kind. If you don't have a clear beach don't go kiting!
- Fully depower the kite before stopping. And unhook your harness before approaching the shore.
- Always wear an effective safety system so in the event of over power you can just let go and the kite will fully depower while still staying attached to you. This requires unhooking first to be effective as in the point above. This is the biggest problem as many kiters get lazy and stay hooked in on the shore with the idea that they can pull their backup safety system if they get dragged - the reality is that even remembering to let go can be difficult when things get out of control. "Chicken loops" are a false sense of security on-shore IMO for those who know what they are although I'm bound to be bailed up for that statement by a lot of kiters - it's not a simple question.
These are the types of things (there are plenty of others) that an experienced instructor should drill into you as "non-negotiable" when kiting. Unfortunately there are lots of youtube videos of experienced kiters flouting these types of rules regularly in the interest of making an "exciting" video so learners quickly forget their importance.
Agreed - the most common injury I've seen is people getting hit in the head by their own boards when they have a leash. Not a pretty sight when a heavy board has a lot of momentum...
