as kiting grows as a sport i find myself getting in close calls with more people.. Sick of getting tangled up with other kiters i've started riding with a referee whistle on my hand.. if i'm riding behind a fellow kiter i let out a whistle so they know i'm there.. or if i'm going to do a transition i let out a whistle so others know that i will be changing directions... i feel every kiter should carry a whistle at all times.. would even come in handy if u got into trouble and were drifting out to sea.. Good winds
I can't whistle loud, but know how to watch for people and know the correct passing rules, and keeping distance. The sentiment is good, but more people need to learn the rules, and show respect, this will solve most problems.
I thought you were joking when I read this but maybe you're not. To be honest - don't ride so close behind someone that it's necessary to use a whistle.
I find that if I've got a tailgater up close and personal and I want to change direction I bear away a bit, make a circle motion with my arm, look back and change direction only when it's safe to do so.
A down loop of the kite (useful technique to learn) is a good idea as you change direction if you're afraid of bumping kites when you take it over the top. This keeps your kite nice and low and adds power to the transition.
I think alerting a down wind kiter (has right of way) that you are close and not going to give way to him is a great idea and would be in the safety interest of all people that kite with you.
boots and whistles go hand in hand u better be rockin one out at core biatch so you can whistle that gay slider breaker swede off the water before he screws it all up again
I might also invest in a "hey ladies check me out" megaphone, a "my beach so @#$% off " foghorn and a couple of "we're from the hills" banjos for the canberra boys.
and would be in the safety interest of all people that kite with you.
