Peter Lynn Arc.
Something like the Charger v3 18m.
It's a Twinskin/Arc. And because of that there are a number of features that might suit you.
There are no inflatable bladders.. So nothing to pop if you crash on ice.
It's got good depower capabilities.
They handle gusts very well.
They water relaunch.
You can self land and launch them safely.
The biggest feature is the auto zenith. Let go of the bar and it'll fly up to the top of the wind window fully depowered, And it'll just stay there until you grab the bar again.
The biggest drawback to the arcs is they arn't competitive, Your not going to win any speed records, or jump the highest or the furthest. But the fact the kite is tame, and super easy to fly launch and land mean it's got other qualities that a more competitive kite might not have.
All of the Arc range from the Guerilla model and onwards would work for you. You will need the larger size for that wind range. Arcs are not like a regular kite they have a much smaller projected area than a standard foil. Peter Lynn have sold them since the early 2000's so there are quite a few older ones kicking about that generally sell for very good prices.
There are no bridles, And the only thing that can happen to them is either tears in the material, or the spars snap. You can replace the spars for home made ones, And often people will use aluminium tube rather than the carbon fibre ones that they came with. Either way a very robust design with a decent following.
